"Albert II of Saxony (Wittenberg upon Elbe, ca. 1250 – 25 August 1298, near Aken) was a son of Duke Albert I of Saxony and his third wife Helen of Brunswick and Lunenburg, a daughter of Otto the Child. He supported Rudolph I of Germany at his election as Roman king and became his son-in-law. After the death of their father Albert I in 1260 Albert II jointly ruled the Duchy of Saxony with his elder brother John I, and thereafter with the latter´s sons." - (en.wikipedia.org 29.10.2019)
