Diether of Nassau

[3][4] It is believed that after his father died in 1276, Diether's mother and sister led a very devout life at Klarenthal Abbey in Wiesbaden.

His younger brother, Count Adolf of Nassau, was elected King of Germany in 1292 and died in 1298 in the Battle of Göllheim.

[1] The so-called Toll War led by King Albert I, against the alliance of the four electors from the Rhineland, in 1301, first required Count Palatine Rudolf I of the Rhine, and then the archbishops Gerhard II of Mainz and Wigbold I of Cologne to submit.

In November 1302, Albert also advanced to Trier and forced Diether, who was abandoned by his country, to a humble peace.

In the spring of 1303, after an uprising of the guilds, Diether had to allow the city of Trier complete freedom of the municipal administration.

As a result of the war with King Albert I, the financial situation of Diether was already very bad, now it became considerably worse.
