The correct answer is B) a Seminole Alliance with the Spanish.
The reason that most contributed to white settlers desire to have the Seminoles removed from Florida was a Seminole Alliance with the Spanish.
In 1817 white settlers wanted their land back from the Seminoles. This was the reason of the first war of three. Andrew Jackson attacked the Spanish Florida territories and force the Indians to go back to the south of the Florida Peninsula. On the second war, the United States troops capture Chief Osceola –the leader of the Seminoles- in October 1837, when they wanted a truce with the government. Finally, after the third war in May 1858, the United States declared the end of the conflict with the Seminoles.
