William McIntosh was a notable figure in the history of Georgia, particularly known for his involvement with the Treaty of Indian Springs in 1825. This treaty involved the cession of lands from the Creek Nation, which McIntosh, a Creek chief, negotiated. The lands ceded were primarily in the Coastal Plain region of Georgia.
The Treaty of Indian Springs was significant as it paved the way for the further displacement of Native American tribes from their ancestral lands in Georgia and other parts of the Southeastern United States. McIntosh's actions, especially his signing of the treaty without the consent of many Creek leaders, ultimately led to his assassination by members of the Creek Nation who opposed the treaty.
In summary, while the treaty had implications for various regions, the specific lands involved in the Treaty of Indian Springs were located in the Coastal Plain of Georgia.
