Early years

John was the eldest son of the Duke George the Bearded (1471-1539), from his marriage to Barbara Jagiellon (1478-1534), daughter of King Casimir IV of Poland. Because of the good relationship between his father to the Habsburg family, he was raised in Brussels, together with the future Charles V. John was introduced at an early age to the business of government by his father, but he soon developed a penchant for idleness, and was more interested in good food, alcohol and parties.

Marriage and death

On 8 March 1505, George agreed with Landgrave William II of Hesse to the future marriage of George's then 7-year-old son John with William's 3-year-old daughter Elisabeth of Hesse (1502-1557). She was the sister of Philip the Magnanimous. William received 25,000 guilders marriage money. The marriage took place on 20 May 1516 in Kassel. Elisabeth leaned towards the Lutheran teachings and soon fell in conflict with her husband and his strict Catholic parents. John is said to have invited Martin Luther, arguing that, if his father was adamantly against Luther, he would for Luther when he inherited the throne. After meeting Luther, and realizing that Luther would not outlive George, John became melancholic and fell ill and finally died.^[1]

Even at John's death bed, his wife and his father disputed religious issues. Elizabeth left Dresden for her wittum in Rochlitz, where she introduced Lutheranism.

John and Elisabeth's marriage was childless. He was buried in Meissen Cathedral and succeeded as hereditary prince of Saxony by his younger brother Frederick.
