Beatrice d'Este

Beatrice d'Este (18 September 1332 – 1387) was a daughter of Obizzo III d'Este, lord of Ferrara and Modena, by his long-time mistress Lippa Ariosti; a papal bull legitimized their children in 1346, and the couple married the next year.

In 1365 she became the second wife of Waldemar I, the Ascani prince of Anhalt-Zerbst, whose residence was Dessau. The marriage was childless, and after Waldemar died in 1368 she lived as a widow until her own death in 1387.
