American pioneer in the context of "Settler colonialism"

The Frontier Thesis, also known as Turner's Thesis or American frontierism, is the argument by historian Frederick Jackson Turner in 1893 that the settlement and colonization of the rugged American frontier was decisive in forming the culture of American democracy and distinguishing it from European nations. He stressed the process of "winning a wilderness" to extend the frontier line further for U.S. colonization, and the impact this had on pioneer culture and character. Turner's text takes the ideas behind Manifest Destiny and uses them to explain how American culture came to be. The features of this unique American culture included democracy, egalitarianism, uninterest in bourgeois or high culture, and an ever-present potential for violence. "American democracy was born of no theorist's dream; it was not carried in the Susan Constant to Virginia, nor in the Mayflower to Plymouth. It came out of the American forest, and it gained new strength each time it touched a new frontier," wrote Turner.

In this view, the frontier experience established the distinctively American style of liberty contrasted to deferential European mindsets still affected by the expectations of feudalism. It eroded old, dysfunctional customs. Turner's ideal of frontier had no need for standing armies, established churches, aristocrats, or nobles; there was no landed gentry who controlled the land or charged heavy rents and fees. Rather, pioneers went and claimed territory for themselves using only loose organizations, and the toughness of the experience gave them discipline and self-sufficiency that would be handed down over generations, even after the frontier advanced beyond the old boundaries. The Frontier Thesis was first published in a paper entitled "The Significance of the Frontier in American History", delivered to the American Historical Association in 1893 in Chicago. He won wide acclaim among historians and intellectuals. Turner elaborated on the theme in his advanced history lectures and in a series of essays published over the next 25 years, published along with his initial paper as The Frontier in American History.

The Seminole Wars (also known as the Florida Wars) were a series of three military conflicts between the United States and the Seminoles that took place in Florida between about 1816 and 1858. The Seminoles are a Native American nation which coalesced in northern Florida during the early 1700s, when the territory was still a Spanish colonial possession. Tensions grew between the Seminoles and American settlers in the newly independent United States in the early 1800s, mainly because enslaved people regularly fled from Georgia into Spanish Florida, prompting slaveowners to conduct slave raids across the border. What began as small cross-border skirmishes became the First Seminole War, as Andrew Jackson led U.S. forces into Florida—despite Spanish objections—to pursue the Seminoles. Jackson's forces destroyed several Seminole, Mikasuki and Black Seminole towns, as well as captured Fort San Marcos and briefly occupied Pensacola before withdrawing in 1818. In 1819 the U.S. and Spain agreed to transfer Florida in the Adams–Onís Treaty; in return, the United States renounced its claims to Texas and fixed the boundary at the Sabine River.

The United States gained possession of Florida in 1821 and coerced the Seminoles into leaving their lands in the Florida panhandle for a large Indian reservation in the center of the peninsula per the Treaty of Moultrie Creek. In 1832 by the Treaty of Payne's Landing, however, the federal government under United States President Andrew Jackson demanded that they leave Florida altogether and relocate to Indian Territory (modern day Oklahoma) as per the Indian Removal Act of 1830. Those who refused to move resisted violently, leading to the Second Seminole War (1835–1842), which was by far the longest and most wide-ranging of the three conflicts. Initially, less than 2,000 Seminole warriors employed hit-and-run guerilla warfare tactics and knowledge of the land to evade and frustrate a combined U.S. Army and Marine force that grew to over 30,000. Instead of continuing to pursue these small bands, American commanders eventually changed their strategy and focused on seeking out and destroying hidden Seminole villages and crops, putting increasing pressure on resisters to surrender or starve with their families.

The American Indian Wars, also known as the American Frontier Wars, and the Indian Wars, was a conflict initially fought by European colonial empires, the United States, and briefly the Confederate States of America and Republic of Texas against various American Indian tribes in North America. These conflicts occurred from the time of the earliest colonial settlements in the 17th century until the end of the 19th century. The various wars resulted from a wide variety of factors, the most common being the desire of settlers and governments for Indian tribes' lands. The European powers and their colonies enlisted allied Indian tribes to help them conduct warfare against each other's colonial settlements. After the American Revolution, many conflicts were local to specific states or regions and frequently involved disputes over land use; some entailed cycles of violent reprisal.

As American settlers spread and expanded westward across the United States after 1780, armed conflicts increased in size, duration, and intensity between settlers and various Indian tribes. The climax came in the War of 1812, when major Indian coalitions in the Midwestern United States and the Southern United States fought against the United States and lost. Conflict with settlers became less common and was usually resolved by treaties between the federal government and specific tribes, which often required the tribes to sell or surrender land to the United States. These treaties were frequently broken by the U.S. federal government.

Manifest destiny was the expansionist belief in the 19th-century United States that American settlers were destined to expand westward across North America, and that this belief was both obvious ("manifest") and certain ("destiny"). The belief is rooted in American exceptionalism and romantic nationalism, implying the inevitable spread of republicanism and the American way. It is one of the earliest expressions of American imperialism.

According to historian William Earl Weeks, there were three basic tenets behind the concept:

Oklahoma (/ˌoʊkləˈhoʊmə/ OH-klə-HOH-mə; Choctaw: Oklahumma, pronounced [oklahómma]) is a landlocked state in the South Central and Southwestern region of the United States. It borders Texas to the south and west, Kansas to the north, Missouri to the northeast, Arkansas to the southeast, New Mexico to the west, and Colorado to the northwest. Partially in the western extreme of the Upland South, it is the 20th-most extensive and the 28th-most populous of the 50 United States. Its residents are known as Oklahomans and its capital and largest city is Oklahoma City.

The state's name is derived from the Choctaw words okla, 'people' and humma, which translates as 'red'. Oklahoma is also known informally by its nickname, "The Sooner State", in reference to the Sooners, American settlers who staked their claims in formerly American Indian-owned lands until the Indian Appropriations Act of 1889 authorized the Land Rush of 1889 opening the land to settlement.

The California genocide was a series of genocidal massacres of the indigenous peoples of California by United States governments, soldiers and settlers during the 19th century. It began following the American conquest of California in the Mexican–American War and the subsequent influx of American settlers to the region as a result of the California gold rush. Between 1846 and 1873, it is estimated that settlers killed between 9,492 and 16,094 Californian Natives; up to several thousand were also starved or worked to death. Forced labor, kidnapping, rape, child separation, and forced displacement were widespread during the genocide, and were encouraged, tolerated, and even carried out by American government officials and military commanders.

The 1925 book Handbook of the Indians of California estimated that California's indigenous population decreased roughly from 150,000 in 1848 to 30,000 in 1870 and 16,000 by 1900 as a result of disease, low birth rates, starvation, and genocide. Between 10,000 and 27,000 were also subject to forced labor by U.S. settlers, with California officials repeatedly passing legislation which disenfranchised Californian Indians.
