Early life
Born as a member of the House of Hohenzollern, John George was the eldest son of Joachim II Hector, Elector of Brandenburg, and Princess Magdalena of Saxony.
Biography
Faced with large debts of 2.5 million guilder accumulated during the reign of his father, John George instituted a grain tax which drove part of the peasantry into dependence on a nobility that was exempt from taxation. He had Jews expelled from Brandenburg in 1573, stripped of their assets and prohibited from returning. Though a staunch Lutheran opposed to the rise of Calvinism, he permitted the admission of Calvinist refugees from the wars in the Spanish Netherlands and France. On 13 July 1574, he founded the Berlinisches Gymnasium zum Grauen Kloster, the first humanistic educational institution in Berlin. He was succeeded by his son Joachim Frederick.
Upon the death of his kinsman Albert I, Duke of Prussia, in 1568, the Duchy of Prussia was inherited by the latter's underage son Albert Frederick. John George's father was a co-inheritor of the Duchy of Prussia. In 1577 the Brandenburg electors became co-regent with Duke Albert Frederick of Prussia.
