Bradenton ( ) is a city in and the county seat of Manatee County, Florida, United States. As of the 2020 census, the city's population is 55,698. History Late 18th and early 19th centuries A settlement established by Maroons or escaped slaves named Angola existed in Bradenton's present area starting in the late 1700s and ending in 1821. It is believed to been spread out between the Manatee River (then known as Oyster River) all the way to Sarasota Bay. The community is estimated to have had 600–750 residents in it. Angola was a rather large maroon settlement as the Manatee River at that time was too shallow for US Navy vessels to navigate. The settlement was abandoned after the Creeks who were aligned with Andrew Jackson attacked Angola. When the United States annexed Florida in 1821, there were two known claimants of land in the vicinity of Bradenton but neither of them was confirmed by the US federal government. Mid and late 19th century Josiah Gates along with his family and eight slaves moved to the area where present-day Bradenton exists in January 1842 after being attracted to the area for its natural beauty. Gates thought the area would be a popular place for new settlers to arrive at because it was near Fort Brooke, and he also figured that while they were building their homes they would need a place to stay at temporarily. He built his home near present-day 15th Street East and his inn at another location naming it Gates House. Gates is also credited as being the first known American settler in present-day Manatee County. Bradenton is named after Dr. Joseph Braden, whose nearby fort-like house was a refuge for early settlers during the Seminole Wars. Braden owned a sugar plantation in the area, covering and being worked by slave labor. Dr. Joseph Braden was originally from Virginia and relocated to Leon County in Florida shortly after its annexation by the United States in 1821 where he established a cotton plantation bringing his preexisting Virginia slaves along with him. After having financial difficulties from the Panic of 1837, he tried to reestablish himself financially in Manatee County in 1843 moving to the area along with his slaves. To help with the shipment of sugar grown at the plantation, he constructed a pier in present-day Downtown Bradenton where ships could dock at and pick up sugar.
