The Arab invasion of North Africa followed immediately after the

conquest of Egypt, but the internal disputes of the Muslim community

prevented this invasion from resulting in a regular conquest, much less

in settlement. It was not until the second invasion took place in A.H.

45 (= A.D. 665) that we can regard the Arabs as really beginning the

conquest of the country and its settlement. For centuries afterwards the

Arab hold was precarious in the extreme, and many Berber states were

founded from time to time, some of which had an existence of several

centuries. As a rule there was a pronounced racial antipathy between Arab

and Berber, but this was mild compared with the tribal feuds between

different Berber groups, and Arab rule was only possible by temporary

alliance with one or other of the quarrelling factions. Strangely enough

the religion of Islam spread rapidly amongst the Berbers, but it took

a peculiar development which shows the survival of many pre-Islamic

religious ideas and observances. The worship of saints and the reverence

paid to their tombs is a corruption of Islam which appears in most lands,

but in the West it takes an extreme form, although there are tribes

which reject it altogether. Similar worship, often in a revolting form,

is paid to living saints or _murabits_ (marabouts), who are allowed to

indulge every passion, and to disregard the ordinary rules of morality:

very often these reputed saints are no more than insane persons, for the

Berbers, like many other primitive people, regard insanity as a form of

divine inspiration. Such saints, even those living to-day, are credited

with miraculous powers, and especially with the power of surpassing the

limitations of time and place, and so to pass from one place to another

in an instant of time, and to be in two places at once.

These ideas, of course, are no legitimate development of Islam, to

which they are plainly repugnant, but represent the survival of older

pagan beliefs which Islam has not been able to eradicate. At the same

time, as we have noted, there are tribes which are completely free from

these ideas, and there is, especially in the towns, an element which is

strictly orthodox in its rejection of alien superstitions, and there

have been many learned theologians and jurists of the Berber race, for

the most part of a reactionary and conservative school of thought.

The conquest of Spain was carried out by Muslims, amongst whom the

Berbers were in the numerical majority, and the Berber element always

predominated in Spain, where some of the most brilliant philosophy,

literature, and art of the Islamic world was produced.

North Africa was always the home of the lost causes of Islam. Whenever

the Khalifs of Baghdad tried to exterminate some obnoxious sect or

dynasty, the last survivors took refuge in the remoter parts of the

West, and there managed to hold their own, so that even now those parts

show the strangest survivals of otherwise forgotten movements. But North

Africa always gave its readiest welcome to those sects which show a

strongly puritan character: though anyone in revolt against the Khalif or

other recognized authority could count on a welcome in North Africa for

that very fact.

In race, language, and religious ideas the Berbers of the North are one

with the Berber tribes of the great desert which spreads to the watershed

of the Benwe and connects, by regular trade routes following the ridges

which traverse North Africa from north-west to south-east, with the Horn

of Africa. But these desert dwellers of the south do not enter into the

subject of our present enquiry.

The Arab conquerors settled along North Africa and down to the desert

edge in sporadic groups, their tribes as a rule occupying the lower

ground, whilst the older population maintained itself in the mountainous

districts. But this does not mean that the Berbers were held at bay

as a subject people: the Katama, for instance, possessed some of the

best territory in North Africa, and were practically independent of the

Khalif. During the invasion of 45 the city of Kairawan was founded some

distance south of Tunis. The site was badly chosen, and it is now little

more than a decayed village, but for some centuries it served as the

political capital of _Ifrikiya_, the province which lay next to Egypt

and embraced the modern states of Tripoli, Tunis, and the eastern part

of Algeria to the meridian of Bougie. West of this lay _Maghrab_ or “the

western land” which was divided into two districts, Central Maghrab,

extending from the borders of Ifrikiya across the greater part of Algeria

and the eastern third of Morocco, and _Farther Maghrab_, which was the

land beyond to the Atlantic coast.

The Berber tribes were spread over all these provinces. In the eastern

part of Ifrikiya the chief were the tribes of _Hwara_, _Luata_,

_Nefusa_, and _Zuagha_: in Central Ifrikiya the _Warghu_ and _Nefzawa_:

in western Ifrikiya the _Nefzawa_, _Katama_, _Awraba_, and a number of

smaller tribes to the south: the chief tribes of Central Maghrab were the

_Zuawa_ (or Zouaves), _Magbrawa_, and _B. Mzab_: and in Farther Maghrab

the _B. Wanudin_, _Ghomara_ (in the Rif of Morocco), the _Miknasa_,

etc. No satisfactory result has ever been attained by those who have

tried to identify the ancient Numidians, Mauritanians, and Gaetuli with

existing tribes; evidently, as in Arabia, there have been new groupings

and new formations, which forbid the tracing back of the mediaeval

tribal divisions to ancient times; perhaps it was Islam which finally

rendered permanent the divisions as they existed in the first century of

the Hijra. Amongst these Berber tribes were spread the tribes of Arab

invaders and settlers which, even in the 10th century A.D. extended in

scattered groups from the borders of Egypt to the Atlantic. For the

most part each race preserved its own language, the Arabic dialects

being distinguished by archaic forms, and a phonology somewhat modified

by Berber influences; but there are several instances of Berber tribes

which have adopted Arabic, and some of Arabs and mixed groups which have

adopted the Berber language. For the most part the Arabs have had no

reluctance to mingle with the Berbers, but the attitude of the Berbers

varies, and some groups rigidly exclude intermarriage between themselves

and the Arabs or any others.

The Kharijites, the oldest and most turbulent dissenting sect of Islam,

the reactionaries who opposed the modification of Muslim customs under

Hellenistic influence, had appeared in Maghrab early in the 2nd century

of the Hijra after their suppression in Asia, and were still a living

force there in the fourth century, when their very name was almost

forgotten elsewhere. A small group of the less extreme branch of that

sect, the Ibadites, still survives in strict isolation in South Algeria.

The Idrisids, a dynasty descended from the house of Hasan the son of

ʿAli, founded by Idris who escaped from the attempted extermination of

his kinsmen at Madina in 169, ruled an independent state in Farther

Maghrab in the fourth century. The Umayyads dethroned by the ʿAbbasids

in 132, had a representative who escaped to North Africa, and then

crossed to Spain where they founded a Khalifate at Cordova which, in

the fourth century, had become a great and flourishing power. Indeed

the Maghrab was too remote from the Khalifs of Baghdad ever to be under

effective control: one after another punitive expeditions marched across

North Africa, the disaffected were defeated, the remnant took refuge in

the hills, and in the course of a few years or even months the former

condition returned again. Obviously those western lands offered a

promising field to the agitator, whether political rebel or sectarian

leader, and Ibn Hawshab’s missionaries had evidently struck a promising

vein in the Berber tribe of Katama.

Amongst those who attached themselves to Ibn Hawshab in Yemen was a

certain Abu ʿAbdullah Hasan (or Husayn) b. Ahmad b. Muhammad b. Zakariya,

afterwards surnamed ash-Shiʿi, a native of Sana and a zealous Shiʿite

who had been inspector of weights and measures in one of the districts

attached to Baghdad. He was a man not only of superior education and

intelligence, but astute and with as good knowledge of how to deal with

men. Before long he became one of Ibn Hawshab’s most trusty companions

and, when the news came of the death of the two missionaries who had

been sent to Africa, Ibn Hawshab determined to send him as _daʿi_,

and provided him with the funds necessary for his enterprise. Later

on we find him in Africa assisted by his brother, but we are without

information as to whether this brother was sent to join him later or set

out with him (Maqrizi ii. 11, Ibn Khallikan i. 465).

Abu ʿAbdullah’s first step was to go to Mecca and to find out where the

Katama pilgrims were lodged. As soon as he discovered this he engaged a

lodging near by and sat as close to them as he could, listening to their

conversation. Before long they began to talk about the prerogatives

of the house of ʿAli, a subject on which they had been instructed by

the two missionaries who had already visited their country, and Abu

ʿAbdullah joined in their conversation. When he stood up to go away

they begged to be allowed to visit him, and to this he assented. They

were delighted with his learning and began to frequent his society,

and one day they asked him where he intended to go when he had finished

his pilgrimage to Mecca. He replied that it was his intention to go

to Egypt, so they begged him to join them as they would have to pass

through Egypt on their homeward journey. They set out together, and

the good opinion they had formed of him was greatly increased as they

observed his piety, his regularity in the exercises of religion, and

his ascetic character. During all this time he mentioned no word of his

real intentions, but constantly directed the conversation to the subject

of the land of Katama, and asked many questions about the neighbouring

tribes and their relation with the governor of Ifrikiya. On this last

subject the Katamites explained that they did not regard the governor

as having any authority over them, his residence was ten days’ journey

from their country, and his control was nil. He further enquired if they

were accustomed to bear arms, and they replied that this was their usual

occupation.

When they reached Egypt Abu ʿAbdullah said farewell to the Katama

tribesmen but, as they expressed deep regret at the idea of leaving him,

they asked what business he had to attend to in Egypt. He replied that he

had no business there but simply intended to become a teacher. “If that

is all,” they said, “our country will offer you a better field, and you

will find more who are disposed to become your pupils, for we know your

worth.” So as they pressed him warmly, he consented to continue in their

company, and went on until they met some of their fellow tribesmen who

came out to meet them. All these had come under the influence of the two

former missionaries and were devoted Shiʿites and, when they heard the

account given by the returning pilgrims, they welcomed Abu ʿAbdullah with

every demonstration of respect.

At length, about the middle of Rabiʿ I. 288 (Feb., 900 A.D.) they reached

home, and every one of his companions pressed the missionary to be his

guest. He declined all these offers of hospitality and asked them to

inform him where was the valley of _al-Khiyar_ (the righteous men). This

enquiry greatly astonished them as no one could remember that such a name

had ever been mentioned in his presence: they admitted, however, that

there was such a place and described its situation, and he then told them

that he would take up his abode there and visit each of them from time to

time. He then set out with some guides to Mount Inkijan where the valley

is situated, and when they arrived there he told his companions, “Here

is the ‘Valley of the righteous men’ and it is on your account that it

is thus named, for one reads in the traditions that ‘the Mahdi will be

obliged to make his migration, and will be helped in his flight by the

Righteous Men who will be on earth at that time, and by a nation whose

name is derived from _kitman_’; it is because you will rise up in this

valley which has been named ‘The valley of the Righteous Men’” (Maq. ii.

11). The derivation of the Berber name _Katama_ from the Arabic _kitman_

“secret” was, of course, no more than a play upon words.

Very soon the dwellers in the vicinity began to spread Abu ʿAbdullah’s

reputation, men came from all parts to visit him, and he completely

swayed a large body of Berber tribesmen amongst whom the Katama tribe

was most prominent. He made, however, no further mention of the Mahdi,

and did not seem to interest himself in the subject. But he connected

his work with that of the two former missionaries and said: “I am the

man entrusted with the sowing of whom Abu Safyan and Hulwani spoke to

you,” and this increased their attachment towards him and his importance

in their eyes (Maq. id. 37). Some, however, regarded him with disfavour,

for evidently there were Berber tribes which had not adopted Shiʿite

doctrines: but the Katama tribe under its chieftain Hasan b. Harun

supported him, and took up arms against those who tried to interfere with

his work. This inter-tribal dispute was the beginning of a long conflict,

which ultimately made the Shiʿites dominant in North Africa. Supported by

the Katama and a number of Kabyle tribes Hasan attacked and captured the

town of Tarrut, and then advanced against Meila.

Already reports of the religious teacher of Mount Ankijan had spread

through the province of Ifrikiya, and had reached Ibrahim b. Ahmad the

Aghlabi Emir. These Aghlabids were hereditary governors of Ifrikiya

established at Kairawan about 184 by the ʿAbbasid Khalifs, to whom

they paid tribute and were subject. Desirous of obtaining more accurate

information Ibrahim had sent to the governor of Meila to make enquiry

about Abu ʿAbdullah and his doings, but the governor had sent back

to Kairawan a somewhat contemptuous account of him, in which he was

described as a religious fanatic, a devotee revered as a saint by the

ignorant people, and so the political possibilities of his activity were

overlooked.

The taking of Tarrut and the advance on Meila, which city, after a brief

resistance, was betrayed by some of its inhabitants, made a change in

this attitude. Ibrahim sent an army under his brother Ahwal against

Abu ʿAbdullah and his followers, and defeated them, after which Ahwal

returned home fully convinced that the rising had been finally disposed

of. From this defeat Abu ʿAbdullah retired to Mount Ankijan where he

established a “house of flight,” and there he gathered his partisans

around him. As soon as he heard of Ahwal’s retirement he began a series

of forays, pillaging the surrounding districts and annoying those who did

not join the Shiʿite sect. At this Ahwal made a new expedition, but this

time he suffered a repulse, not severe enough to force him to retreat,

but compelling him to be satisfied with a defensive police duty in the

neighbourhood which was, however, effectual in checking the Shiʿite

raids. But this did not last long. In 291 (= A.D. 903) Ibrahim the

Aghlabi died, and the governorship passed to his son Ziadat Allah, a man

indolent and entirely devoted to pleasure, who recalled his brother Ahwal

from his military duties.

This, of course, opened new opportunities for Abu ʿAbdullah, and very

soon his followers were ranging at will through the whole province of

Ifrikiya, and he boldly declared that the Mahdi was now near at hand

and would soon appear in Africa, and would prove his sacred mission by

working miracles (Maq. ii. 11). Common report affirmed that Abu ʿAbdullah

himself had done many wonders, even making the sun rise in the west,

restoring the dead to life, and other marvels. Not only had he now a very

large following amongst the Berber tribesmen, but many of the officers

serving under Ziadat Allah were well disposed towards the Shiʿite

claims, and were secretly in correspondence with Abu ʿAbdullah.

At this juncture, in 291, the Shiʿites were practically supreme in all

the country west of the suburbs of Kairawan, and now Abu ʿAbdullah sent

messengers over to the Mahdi inviting him to cross into Africa. Ismaʿil

had just died at Salamiya, and shortly before his death advised his son

Saʿid to migrate to a distant land. As soon as his father died Saʿid and

his son Abu l-Kasam Nizar set out from Salamiya intending to go to Yemen,

but hearing of the success in North Africa changed their course in that

direction, probably meeting the messengers from Abu ʿAbdullah on the way

(cf. Ibn Khaldun ii. 515-516). The journey was beset with great perils,

especially in the passing through Egypt. At that time the governor of

Egypt was Abu Musa Isa b. Muhammad Nushari, who had been appointed after

the death of Ibn Tulun in 292, and held office until the government was

usurped by Khalanj in 293-4, after which the Khalif al-Muqtadi restored

him to office which he held until his death in 297. Saʿid, or ʿUbayd

Allah as he now preferred to call himself, arrived during this latter

period of office, and the governor had grounds of suspicion about him

without very clear information. The refugees left Misr, the old capital

lying to the south of the present Cairo, but the governor followed

and overtook them. He attempted no violence, but joined their company

and induced them to rest with him in a garden, his guard meanwhile

surrounding the place. He tried every means to win their confidence, and

so to find out who they were and what was the object of their journey: he

tried to coax ʿUbayd Allah to join him in taking refreshment, but ʿUbayd

Allah declined on the pretext that he was then observing a fast: then he

tried to get information by judicious questions, but in vain. At length

he allowed ʿUbayd Allah to go on his way. He offered the travellers an

escort, but this was politely declined. Then the governor assembled

his men to return home, but many of them showed their discontent that

the travellers had been allowed to escape, and on second thoughts the

governor himself regretted that he had not detained them for further

enquiry, and sent a body of men after them, but they had made good use

of their start, and it proved impossible to overtake them. Some said that

the governor had been bribed by ʿUbayd Allah, and this seems to be likely

enough.

After this escape ʿUbayd Allah, his son, and Abu l-ʿAbbas, the brother

of Abu ʿAbdullah, went on to Tripoli. The next town on their way would

be Kairawan, and ʿUbayd Allah was distinctly anxious about venturing

there, so he sent forward Abu l-ʿAbbas to obtain information. Now it

appears that Ziadat Allah had much clearer grounds of suspicion than the

Egyptian governor, and Abu l-ʿAbbas was not able to escape suspicion,

and was taken prisoner. Ziadat Allah does not seem to have been so much

interested in the prisoner himself, but made every endeavour to find

out some details about the companions with whom he was travelling. Abu

l-ʿAbbas denied that he had travelled with any companions, or that he

had any knowledge of a fugitive from Syria: he asserted that he was

simply a merchant passing through Ifrikiya on his own business. But

Ziadat Allah’s suspicions were not allayed: Abu l-ʿAbbas was detained in

custody, and a messenger was sent to Tripoli to secure the arrest of the

other travellers. The messenger, however, returned with the reply that

ʿUbayd Allah had already left the city before the order for his arrest

had arrived. Again the suggestion is made that the governor of Tripoli

had been won over by bribes. It is supposed that ʿUbayd Allah had been

able to take with him a great part of his considerable wealth, and that

it was easy for him to corrupt the provincial governors. Certainly he had

information of what had befallen Abu l-ʿAbbas in Kairawan. At first he

retired to Kastilia, but when he made sure that there was no possibility

of Abu l-ʿAbbas getting free and joining him there, he went on to

Sijilmassa (Maq. ii. 11).

At the time of his arrival in this town the ruling prince, al-Yasa b.

Midrar, had no grounds of suspicion, and received the travellers very

kindly. ʿUbayd Allah made him valuable presents, and they soon became

intimate. One day, however, as they were sitting together, a letter from

Ziadat Allah was put into al-Yasa’s hand, and in it the Aghlabi related

the suspicions he had formed about ʿUbayd Allah. The governor immediately

ordered the arrest of ʿUbayd Allah and his son, questioned them closely

about their relations with Abu l-ʿAbbas, and the suggestion that they

were in some way associated with Abu ʿAbdullah, but ʿUbayd Allah denied

any knowledge of either of these. The father and son were then separated

and confined in separate quarters, and the son, Abu l-Kasam, was examined

apart, but no information of any sort could be obtained from him.

Meanwhile, since the departure of the messengers from Abu ʿAbdullah to

ʿUbayd Allah, the former had continued his career of conquest. Meila,

Satif, and other towns immediately near the Katama territory were taken,

and the governor at Kairawan was no longer able to disguise from himself

that the Shiʿite revolt was threatening the very basis of Arab authority

in Ifrikiya. Under these circumstances Ziadat Allah assembled a council

of canonists to advise him about the Shiʿite claims. The meeting took

place in the house of the prince’s chief adviser, Abdullah b. Essaig,

and, after considering the religious character of Abu ʿAbdullah’s

movement, and especially the report that “he cursed the Companions,”

_i.e._, that he was a Shiʿite who cursed the first three Khalifs as

usurpers who had excluded ʿAli from his rights, regardless of the fact

that they had been the companions of the Prophet, they decided that Abu

ʿAbdullah and his followers must be publicly denounced as heretics.

Fortified with this decision which was necessary to stop the tendency of

his own people to favour the Shiʿites, the Aghlabid assembled an army

of 40,000 men whom he placed under a kinsman named Ibrahim b. Habashi

b. ʿUmar at-Tamimi, and sent them against the Katama. Ibrahim took up

his quarters at Konstantina l-Hawa, on the western edge of the Katama

country, and there he stayed six months without actually attacking

the Shiʿites, but serving as a check upon their movements. As soon as

he appeared Abu ʿAbdullah retired to his usual retreat, “the house of

flight,” and no further advance was made on either side. As Ahwal had

already proved, this kind of patrol work was the most effective. But

Ibrahim desired a decisive punishment of the revolted tribes, and rashly

resolved to move out and attack Kerma, one of the cities occupied by the

Shiʿites. On the way Abu ʿAbdullah met and defeated him, and he had to

flee with the remnants of his army to Kairawan.

Matters were now becoming extremely serious, and Ziadat assembled a new

force which he entrusted to Harun b. Tabni. Harun marched upon Daralmoluk

and took it, but immediately afterwards Abu ʿAbdullah arrived with his

main band, and a general engagement ensued, in which Harun was killed and

his forces completely routed. After this victory Abu ʿAbdullah marched

upon Banjas, which capitulated, and then was in a position to threaten

Kairawan itself. We have now reached the year 295, and at this point

Ziadat Allah raised a third army and took command himself. He advanced

to Elaris, but there his courtiers began to remonstrate with him: if any

disaster took place and he were involved it would mean the downfall of

the Aghlabid dynasty, a result which would not necessarily proceed from

the defeat of a subordinate general. Persuaded by his entourage Ziadat

Allah appointed his kinsman Ibrahim as commander-in-chief, and himself

retired to Raqada to the south-west of Kairawan, and gave himself over

entirely to a life of pleasure.

Meanwhile Abu ʿAbdullah was extending his authority over the whole

country. He was invited to Bagaya which he occupied, then took by force

the small towns of Majana, Sash, and Maskanaya. His politic clemency at

Bagaya produced a good impression, and did much to assist him in gaining

over other towns. His success caused great alarm to Ziadat Allah, and

he consulted ʿAbdullah b. Essaig, who advised him to retire to Egypt

and leave a general in charge of the army, but Ibrahim persuaded him to

abandon this idea. Soon afterwards Abu ʿAbdullah advanced to Merida,

where were many refugees from the towns already taken. The inhabitants

asked for terms, and Abu ʿAbdullah’s lieutenants agreed, the leader

himself being absent. When the envoys from the citizens returned and the

gates were opened to admit them, the attacking army made a sudden rush,

forced their way in, and pillaged the city.
