His father was General and
Breisach fortress commander Franz Christoph von Rodt (1671–1743). Von Rodt was elected
Bishop of Constance in 1750, succeeding his maternal uncle,
Kasimir Anton von Sickingen. One of his successors was his brother
Maximilian Christof von Rodt.
Pope Benedict XIV created him a cardinal in the consistory of 5 April 1756. On 2 August 1758, he became Cardinal Priest of the Titular Church of
Santa Maria del Popolo. Von Rodt participated in the
conclave of 1758, in which Clement XIII was elected, but he did not participate in the
conclaves of 1769 (election of Clement XIV) and
1774-1775 (election of Pius VI). Franz Konrad von Rodt died in 1775 of a stroke in his Bishop's residence, the
Neues Schloss in Meersburg and was buried in the choir of its Catholic parish church. ==See also==
