Final answer:
The Seminoles separated from the Creeks to maintain autonomy and developed a close relationship with Black Seminoles, leading to strong resistance against U.S. Government efforts to reunify the tribes for removal. They fought to preserve their distinct identity, culminating in the Seminole Wars where they vehemently resisted relocation to Indian Territory.
Step-by-step explanation:
The separation of the Seminoles from the Creeks originates from a process of migration and differentiation. The Seminoles, originally part of the Creek Nation, began to migrate into Florida in the early 18th century, partially to distance themselves from the European-American settlers and the encroachment on their traditional lands. Over time, the Seminoles developed a distinct identity through their interactions with Spanish colonists and African slaves who had escaped from English colonies, with many Seminoles forming alliances and intermarrying with these African communities, known collectively as the Black Seminoles.
The Seminoles rejected the U.S. government's idea of rejoining the two tribes for removal due to their strong desire for autonomy and to maintain their distinct social and cultural identity. They had established a unique relationship with the Black Seminoles, which was significantly different from the relationships between African slaves and the Creek Nation. The Seminole Wars, which demonstrated the Seminoles' fierce resistance to U.S. military efforts at removal, further cemented their resolve to stay separate from the Creeks and retain their independence in Florida.
