Hallandale Beach, like most of Broward County, had no permanent European-descended population until the end of the 19th century.
Native Americans (Seminole Indians), in settlements that lay inland of the Atlantic shore, hunted in the area and gathered coontie roots to produce arrowroot starch.
Railroad magnate Henry Flagler, owner of the Florida East Coast Railway, recruited Luther Halland, a brother-in-law of Flagler's agents, to found a settlement south of the community of Dania. Halland and Swedish immigrant Olaf Zetterlund touted the frost-free climate and cheap land of the settlement (then named Halland, later changed to Hallandale). Halland constructed a small trading post and became the first postmaster of the small community.
By 1900, the community had slowly grown to a dozen families—seven of Swedish, three of English, and two of African descent. In 1904 the first school was built, and the first church followed two years later. Hallandale was primarily a farming community; the beach was undeveloped and used by the residents only for recreational purposes.
Hallandale was incorporated on 14 May 1927. By that time, a thriving community of 1,500 residents, with electricity and street lights, was in place. In 1947, Hallandale was reincorporated as a city, allowing it to expand its borders through annexation of nearby unincorporated land lying adjacent to the Atlantic shore. In August 1999, the city officially changed its name to Hallandale Beach.
