Adolf I von Nassau

[1] When his uncle, Archbishop of Mainz Gerlach von Nassau [de; fr] died in 1371, he was chosen by the Cathedral chapter as his successor against Kuno II von Falkenstein; however, he had to yield to Johann von Luxemburg-Ligny [de], the preferred candidate of Emperor Charles IV, who was appointed by Pope Gregory XI.

[3] When Johann died in 1373, the Mainz Cathedral chapter again supported Adolf, but on the request of Emperor Charles IV, Gregory XI appointed Louis of Meissen.

[2] After the death of Gregory XI, Adolf used the Western Schism and had himself confirmed by the Avignon pope Clement VII.

[2] During his reign, Adolf was in conflict with Rupert I, Elector Palatine, a supporter of the Roman papacy.

[4] On Adolf's initiative, the creation of the University of Erfurt was confirmed by Pope Urban VI in 1389.
