John II of Brandenburg-Stendal

John II (1237–1281) was the eldest son of Margrave John I and Sophie of Denmark, and from 1266 co-ruler of the Brandenburg-Stendal line alongside his brothers Otto IV and Conrad I, politically overshadowed by Otto IV. In 1269 he co-signed the Treaty of Arnswalde with Duke Mestwin II of Pomerelia.

His record centres on Chorin Abbey, the Cistercian house founded by his father: in 1273 the three brothers confirmed moving it from Mariensee to Chorin, where John was buried on his death in 1281.
