Answer:
Seminole originally belonged to Georgia and Alabama as the same as creeks but later on Seminoles shifted to Florida to enjoy a better life and a peaceful life because of the conflicts with European and other tribes.
Seminole did not want to join creek again because they had settled well in Florida and had cordial relation with the adjoining nations and were considered to be civilized and some of the treaties also promised lands to the Seminoles and this tribe did not want to leave this lifestyle.
