The Duchy of Anhalt was a historical German duchy. The territory is now part of the federal state of Saxony-Anhalt.
Anhalt's origins lie in the Principality of Anhalt, a state of the Holy Roman Empire.
During the 9th century, most of Anhalt was part of the duchy of Saxony. In the 12th century, it came under the rule of Albert the Bear, margrave of Brandenburg. Albert was descended from Albert, count of Ballenstedt, whose son Esico (died 1059 or 1060) appears to have been the first to bear the title of count of Anhalt. Esico's grandson, Otto the Rich, count of Ballenstedt, was the father of Albert the Bear, who united Anhalt with the Margraviate of Brandenburg (March of Brandenburg). When Albert died in 1170, his son Bernard, who received the title of duke of Saxony in 1180, became count of Anhalt. Bernard died in 1212, and Anhalt, separated from Saxony, passed to his son Henry I, who in 1218 took the title of prince and was the real founder of the house of Anhalt.
