From that time of contact, Florida has had many waves of immigration, including French and Spanish settlement during the 16th century, as well as entry of new Native American groups migrating from elsewhere in the South, and free blacks and fugitive slaves, who became known as Black Seminoles. Florida was under colonial rule by Spain and Great Britain during the 18th and 19th centuries before becoming a territory of the United States in 1822. Two decades later, in 1845, Florida was admitted to the union as the 27th US state. Since the 19th century, immigrants have arrived from Europe, Latin America, Africa and Asia.
Florida is nicknamed the "Sunshine State" due to its warm climate and days of sunshine, which have attracted northern migrants and vacationers since the 1920s. A diverse population and urbanized economy have developed. In 2011 Florida, with over 19 million people, passed New York and became the third largest state in population.
