Westward Expansion was a period of colonization in the Americas where the United States began to explore more and more territories out west and eventually, take over all of the USA's modern territories, expanding from Atlantic to Pacific. They fought several native tribes along the way, eventually subjugating them all.


The American nation was an infant nation that was strong and ambitious. The American people believed in the "American Dream", hoping for freedom, so many people moved out west into Indian territory to make a better life for themselves. The American government under President Elias Boudinot began to expand their country to the Pacific coast, beginning the "Westward Expansion" period.

Iroquois War

The Americans began their period of warfare with the Indian tribes by declaring war on the Iroquois Confederacy, who were allied to Great Britain, which triggered the Anglo-American War. The Americans took over the Iroquois capital of Cayuga in the Iroquois Territory in 1784, before also seizing Niagara, the capital of the Algonquin Territory, which hammered the Iroquois nations. After a lengthy campaign against the Cherokee Nations, they resumed the war against the Iroquois, taking out Fort Ponchartrain du Detroit and Fort Sault Ste. Marie by 1795, taking over the regions and ending the Iroquois tribe.

Cherokee Campaign

In the meantime, the United States dispatched General John Sullivan to mount a campaign against the Cherokee, who were weak and possessed the Cherokee Territory and the Kaintuck Territory, two tobacco-producing regions that could boost the US economy. Sullivan took them over with relative ease, as the capitals of Chicasa and Tellico (respectively) were adjacent to one another and were easily seized due to the advanced technology that the US possessed, including rifles. The Americans took over the two cities, before expanding into Florida, ending the Cherokee by 1792 with the Siege of St. Augustine, which was the capital of Florida.

Plains Indians Wars

The war with the Cherokees brought their ally, the Plains Nations, into the fore. They were led by Waneta I, who was the chief since 1783. From 1785 to 1800, the Plains Nations raided US settlements across the border, until John Sullivan and the American militiamen seized Yankton, the capital of the Black Hills, which eradicated Waneta's empire.
