The earliest known identification of the area known today as Sarasota, Florida, was identified on a sheepskin Spanish map from 1763 with the word "Zarazote" written over the location of present-day Sarasota and Bradenton. The municipal government of Sarasota was established when it was incorporated as a town in 1902. Incorporation under the city form of government followed in the next decade. In 1921, Sarasota County was formed out of Manatee County, with Sarasota city serving as the county seat.
