Leopoldinen-stiftung im Kaisertume Österreich.

Austrian mission society founded in 1828 by John Frederick Résé, a German missionary who worked in the Diocese of Cincinnati from 1824 until 1833, when he became the first Bishop of Detroit. It imitated the French Society for the Propagation of the Faith: members prayed for and contributed alms to the American missions.

Locally collected funds went to the central office in Vienna and from there to American bishops and congregations of religious. The society published its annual Berichte der Leopoldinen Stiftung im Kaisertume Österreich, which contained letters from missionaries and financial reports. The society survived until 1921.
