He was the youngest child of Duke
John I and his third wife Agnes of Lindow-Ruppin. Albrecht I was probably born in 1367. After his father's death, he ruled Mecklenburg-Stargard jointly with his elder brothers
John II and
Ulrich I. In 1395 he moved to
Livonia to become coadjutor to bishop Dietrich Damerau of Dorpat. He settles a dispute between his bishop and
Konrad von Jungingen, the
Grand Master of the
Teutonic Knights. Early in 1396, Konrad writes in his diary:
the bishop of Dorpat has invited one of the Lord of Mecklenburg and given him several castles and intends him to succeed to the bishopric. Albert died in
Dorpat between 11 February and 15 July and was buried there. == External links ==
