_Osnaburg Bishopric_ (Vol. ii. p. 358.).--By the treaty of Osnaburg, in
1624, it was stipulated "that the alternate nomination to the Bishopric of
Osnaburg should be in the catholic bishops, and in the protestant branches
of the house of Luneburg." Thus, the Princes Ernest Augustus, the father of
George I., Ernest Augustus, brother of the same monarch, and the late Duke
of York, became sovereign-bishops of Osnaburg. But by the treaty of Vienna,
in 1815, the bishopric became an integral part of the kingdom of Hanover.
