William I (died 16 April 963) is the first known member of the house of the Counts of 
Weimar.

Life[edit]

William was first mentioned in a 949 deed as a count (Graf) in Thuringia. Originating 
from the Saalfeld region, he held large estates around Weimar, Jena, and Apolda, 
possibly stemming from late Duke Burchard of Thringia, whose sons were expelled by 
King Henry the Fowler in 913.

He was probably married to a daughter of the Babenberg duke Poppo of Thuringia, 
margrave of the Sorbian March, who had been deposed by the East Frankish king 
Arnulf in 892. William too appeared in the rank of a Thuringian margrave. From 953 to 
955, he and several Wettin counts joined the revolt of Duke Liudolf of Swabia against 
King Otto the Great, wherefore he was temporarily deposed and exiled to the court of 
Otto's brother Duke Henry of Bavaria. By 956, however, William was re-installed into 
his offices.

He had at least three children:
William II (d. 1003), called the Great, succeeded his father as Count of Weimar, Duke 
of Thuringia from 1002
