The Treaty of The Hague is a treaty signed on 12 April 1433, in which Jacqueline, Countess of Hainaut transferred the Dutch territories of her Bavaria-Straubing inheritance to Philip the Good, Duke of Burgundy. Jacqueline had fought over the counties of Holland, Zeeland, Hainaut and Friesland since the death of her father William VI of Holland in 1417 first against her uncle John and then against duke Philip. In 1428, defeated by Philip, she was forced to sign the Treaty of Delft, which named Philip as her heir if she died without offspring and forbade her to remarry without the consent of Philip. In 1432, after she married Frank van Borssele, Philip claimed that the Treaty of Delft had been broken and demanded that Jacqueline abandon all her rights to him; the treaty of The Hague of 1433 formalized this abandonment. Jacqueline died just three years later. Her Dutch lands were eventually merged into the Habsburg Empire.
