most of them were evacuated to Cuba when the Spanish ceded Florida to the British in 1763, under the terms of the Treaty of Paris (1763), which ended the Seven Years' War. Although control of the area changed between Spain, the United Kingdom, the United States, and the Confederate States of America, it remained largely undeveloped until the 20th century. The Fort Lauderdale area was known as the "New River Settlement" before the 20th century. In the 1830s, there were approximately 70 settlers living along the New River. William Cooley, the local Justice of the Peace, was a farmer and wrecker, who traded with the Seminole Indians. On January 6, 1836, while Cooley was leading an attempt to salvage a wrecked ship, a band of Seminoles attacked his farm, killing his wife and children, and the children's tutor. The other farms in the settlement were not attacked, but all the white residents in the area abandoned the settlement, fleeing first to the Cape Florida Lighthouse on Key Biscayne, and then to Key West. The first United States stockade named Fort Lauderdale was built in 1838, and subsequently was a site of fighting during the Second Seminole War. The fort was abandoned in 1842, after the end of the war, and the area remained virtually unpopulated until the 1890s. It was not until Frank Stranahan arrived in the area in 1893 to operate a ferry across the New River, and the Florida East Coast Railroad's completion of a route through the area in 1896, that any organized development began. The city was incorporated in 1911, and in 1915, was designated the county seat of newly formed Broward County. Fort Lauderdale's first major development began in the 1920s, during the Florida land boom. The 1926 Miami Hurricane and the Great Depression of the 1930s caused a great deal of economic dislocation. In July 1935, an African-American man named Rubin Stacy was accused of robbing a white woman at knifepoint. He was arrested and being transported to a Miami jail when police were run off the road by a mob. A group of 100 white men proceeded to hang Stacy from a tree near the scene of his alleged robbery. His body was riddled with some 20 bullets. The murder was subsequently used by the press in Nazi Germany to discredit U.S. critiques of its own persecution of Jews, Communists, and Catholics. When
