Albert I, Prince of Anhalt-Zerbst

Albert I (c. 1258–1316) of the House of Ascania was the second Prince of Anhalt-Zerbst, ruling after his father Siegfried's abdication in 1290 and formally from 1298. In 1293 he abolished Polabian as a court language, and from 1295 he was the first Ascanian prince to reside at Köthen Castle.

Around 1307 he secured the Brandenburg-held part of Zerbst as a fief. After King Albert I's murder in 1308, Margrave Waldemar of Brandenburg proposed him as King of the Romans, in vain.
