John of Beaumont
He was born as John of Hainault, lord of Noordwijk, Beaumont, Gouda and Schoonhoven. He was born most likely in 1288 as son of count John II, Count of Holland and Philippa of Luxembourg. He was the brother of Alice of Hainault.
When his uncle John I, Count of Holland died in 1299, he left behind no descendants. As a result, his father inherited the county of Holland and Zeeland as John II, Count of Holland through his mother Adelaide of Holland. From then on Hainault and Holland were in a personal union. John of Hainault bought the heerlijkheid (comparably to the English Barony) of Beaumont, located in the southern Netherlands, for his son.
Count John II of Holland died in 1304 and was succeeded by his eldest son William III of Holland. On 21 June 1308, John received from his brother all the possessions of Gerard van Velsen, Willem van Zanden and Gerard Craaitenhout. This included the heerlijkheid Noordwijk and Beverwijk. On 23 July 1313 Noordwijk and Beverwijk were raised to hoge heerlijkheid (literally: high barony), which placed them amongst the most important fiefs in Holland. In 1316 John became lord of Tholen. Goes also came into his possession after it was taken from the Borssele family. His most important residences were Beaumont and the castle of Schoonhoven in the southern Netherlands. In 1340 he founded a Carmelite monastery in Schoonhoven.
John married Margaret of Soissons, which gave him the title of Count of Soissons. John and Margaret had five children:
- Jeanne of Hainault, married first to Louis II, Count of Blois, (three sons), and second to William I, Marquis of Namur, no issue
- John, Canon of Cambrai
- William, Canon of Cambrai, Beauvais and Le Mans
- Amalrik, Canon of Cambrai, Dole and Tours
- Reinout, Canon of Cambrai.
John often replaced his absent brother as governor of Holland. In 1326 he led an expedition to England, through which king Edward II of England was driven out and replaced by king Edward III. In 1340 he was regent of Holland and Zeeland for his nephew, count William IV of Holland for a short time. In 1345 he led an expedition to Friesland together with William IV. At the battle of Warns William IV was killed by the frisians while John of Beaumont barely managed to escape. He claimed the right of succession to the three counties, but eventually the succession was awarded to the sister of count William IV. As a result, John left the Netherlands and travelled to France, and he was present at the Battle of Crecy. Here his son-in-law Louis II, Count of Blois was killed. This made his grandson John II, Count of Blois heir to the expensive possessions in Holland and Zeeland. Afterwards John resided at the court of Margaret of Burgundy
He died on 11 March 1356.
