Ludovico Madruzzo (1532-1600)[1] was an Italian Roman Catholic cardinal and statesman, the Imperial crown-cardinal and Prince-Bishop of the Bishopric of Trento (involving the secular rule as well as church duties).
In 1550 his uncle Cristoforo, named Governor of Milan, entrusted him the administration of the Bishopric of Trento, where the Council of Trent had been in intermittent progress since 1545; it was to continue until 1563.
After numerous important diplomatic and political experiences (including the mourning discourse at Charles V's funeral), he was created cardinal in 1561 by Pope Pius IV, given the titular church of San Callisto.
[1] Under agreements between Bernardo Clesio and Cristoforo Madruzzo, the bishopric had gained a substantial independence from the Habsburg-controlled county of Tyrol, and this caused strife between Ludovico and the Austrian archduke (and future emperor) Ferdinand II.
The latter invaded Trentine territory in 1567, and Ludovico moved to Rome, waiting for a diplomatic resolution of the conflict.
