BIOGRAPHY Jan I, Heer van Egmond, was born about 1310, the son of Wouter II, Heer van Egmond, and Beatrijs van de Doortoge. He was lord of Egmond and IJsselstein, bailiff of Kennemerland (1353-1354) and governor of Holland. Jan was first mentioned in 1328 taking part in the Battle of Cassel, and he supported Willem III 'the Good', Graaf van Holland and Hainault, against the rebels of Brugge. About March 1331 he married Guyotte van Amstel, heiress of IJsselstein, only child of Arnoud van Amstel, Heer van IJsselstein, Oudshoorn en Aarlanderveen, and Maria d'Avesnes, the illegitimate daughter of Guy d'Avesnes, bishop of Utrecht, a son of Jan I d'Avesnes, count of Hainault and Aleida of Holland. Jan and Guyotte had at least ten children of whom Arend and Gerrit and four daughters would have progeny. Through his wife he inherited IJsselstein when his father-in-law died in 1362. In 1343 he was appointed among the nobles ruling the land during the absence of the count. In 1344 the castle of Nieuwendoorn (Enigenburch) was added to his estate. He took part in the third campaign of Willem IV, Graaf van Holland and Hainault, to Prussia, and was also involved in the Siege of Utrecht in 1345, but he was not present at Willem's defeat by the Friesians at the Battle of Warns (Stavoren) in that year, in which Willem was killed. In the following years Jan played an important role in the politics of Holland. In January 1350 he was one of the main signatories to the covenant which formed the Kabeljauwse (Cod) League, supporting Willem V, Graaf van Holland and Hainault, against his mother Margaretha, Gravin van Holland, Zeeland en Henegouwen (the successor to her brother Willem IV), for control of Holland and Hainaut, which triggered the wars between the Cods and the Hook (Hoeken) party supporting Margaretha. He was present at the Battle of Naarden in 1350, and fought in the Battle of Zwartewaal (also called the Battle of the Meuse). Jan was then sent to England to negotiate for Willem in his dispute with his mother, but it remained unresolved. On his return to Holland he launched a campaign against the citizens of Bunschoten. When the war against the Hooks was resumed at the end of the winter of 1356, on the orders of Willem V he besieged the castle of Nyevelt, capturing it after seven weeks, which brought the war to an end. In that year Willem VI appointed Jan governor (stadhouder) of Holland north of the river Maas, which he exercised in conjunction with his brother Gerrit. After Willem V was declared insane in 1357, Jan took part in the ministry of Willem's younger brother Albrecht von Bayern, who acted as regent for the rest of Willem's life, and succeeded him as Graaf van Holland, Zeeland and Henegouwen after his death. Jan is mentioned as one of Albrecht's counsellors in 1358. As one of the leaders of the Cod party Jan signed the Treaty of Delft in 1359. For the rest of his life he was among those close to Albrecht. Jan died on 28 December 1369, and was buried in the church of IJsselstein.
