Agnes of Habsburg

Agnes of Habsburg (1257–1322), born at Rheinfelden, was a daughter of King Rudolph I of Germany and Gertrude of Hohenberg. On 24 October 1273, her father's coronation day at Aachen, she married Duke Albert II of Saxony, who had cast his vote for Rudolph, sealing the Ascanian–Habsburg alliance.

When Saxony was partitioned in 1296 she became Duchess of Saxe-Wittenberg, and after Albert's death in 1298 she was regent for her minor son Rudolf I until 1302. She died at Wittenberg on 11 October 1322.
