September 27, 1275 the birth of John II, Duke of Brabant. He was known as the peaceful.
He was the son of John the Victorious, Duke of Brabant who was venerated as a folk hero, the perfect example of a chivalric prince. His mother was Margaret of Flanders, daughter of Guy of Dampierre, Count of Flanders. John was the second of four children. His elder brother Godfrey died though in 1283 at 9. His sister Margaret married Henry VII, Holy Roman Emperor with whom she had three children including Marie of France (wife of Charles IV). His sister Maria married Amadeus V, Count of Savoy as his second wife and bore him 4 daughters.
John succeeded his father as Duke in 1294. He worked to help support a fight against French expansion.
In 1309 the Crusade of the Poor came into the borders of Brabant. It was a group of poor men who had assembled a militia of sorts from France, England, Germany and Brabant. Along their way to join the Papal army they started looting, getting into conflict with local authorities and persecuting Jews. Over 100 Jews had been massacred by the 'brothers of the cross' when they had tried to seek refuge in the castle of Born in Guelders.
The Jews of Leuven and Tienan sought sanctuary after the massacre in Guelders. They sought refuge in the castle of Genappe. John sent his troops to Genappe to drive the crusaders away from the castle, to protect the Jews who he believed he owed protection to in his lands. The crusaders suffered heavy casualties at the hands of John's troops.
In 1312 John signed the Charter of Kortenberg in an attempt to secure a peaceful transition to his son. A charter of rights like the Magna Carta, it was far more democratic, giving rights not simply to the Barons like in England.
He died October 27 of that years in Tervuren. He had been suffering from kidney stones for some time. He was buried at St. Michael and Gudula Cathedral in Brussels.
