II's line, the English Parliament passed the Act of Settlement 1701, which provided that if Anne died without surviving issue and William failed to have surviving issue by any subsequent marriage, the Crown would pass to a distant relative, Sophia, Electress of Hanover (a granddaughter of James I) and to her Protestant heirs. The Act debarred Roman Catholics from the throne, thereby excluding the candidacy of several dozen people more closely related to Mary and Anne than Sophia. The Act extended to England and Ireland, but not to Scotland, whose Estates had not been consulted before the selection of Sophia. Death In 1702, William died of pneumonia, a complication from a broken collarbone following a fall from his horse, Sorrel. It was rumoured that the horse had been confiscated from Sir John Fenwick, one of the Jacobites who had conspired against William. Because his horse had stumbled into a mole's burrow, many Jacobites toasted "the little gentleman in the black velvet waistcoat". Years later, Winston Churchill, in his A History of the English-Speaking Peoples, stated that the fall "opened the door to a troop of lurking foes". William was buried in Westminster Abbey alongside his wife. His sister-in-law and cousin, Anne, became queen regnant of England, Scotland and Ireland. William's death meant that he would remain the only member of the Dutch House of Orange to reign over England. Members of this House had served as stadtholder of Holland and the majority of the other provinces of the Dutch Republic since the time of William the Silent (William I). The five provinces of which William III was stadtholder—Holland, Zeeland, Utrecht, Gelderland, and Overijssel—all suspended the office after his death. Thus, he was the last patrilineal descendant of William I to be named stadtholder for the majority of the provinces. Under William III's will, John William Friso stood to inherit the Principality of Orange as well as several lordships in the Netherlands. He was William's closest agnatic relative, as well as grandson of William's aunt Henriette Catherine. However, Frederick I of Prussia also claimed the Principality as the senior cognatic heir, his mother Louise Henriette being Henriette Catherine's older sister. Under the Treaty of Utrecht (1713), Frederick I's successor, Frederick William I of Prussia, ceded his territorial claim to Louis XIV of France, keeping only a claim to the title. Friso's posthumous son, William IV, succeeded to the title at his
