[citation needed] In August 1797, French invasion troops under General Masséna occupied Trent.

But they returned in January 1801, and after the Treaty of Lunéville on 9 February 1801, the prince-bishopric of Trent was abolished and its government secularized (1803); its territory was handed over to Austria and made a part of the County of Tyrol.

[25] Cardinal Ludovico Madruzzo (1567–1600) held a diocesan synod in 1575, in which it was decreed that clerics should not grow mustaches, since it might interfere with drinking the blood of Christ from the communion cup.
