The Southwest came under United States control as a result of the Mexican War. In 1847, Pueblo Indians rose up against settlers at Taos (later in New Mexico) and were defeated. But relations between settlers and the Pueblos, Pimas, and Papagos were usually peaceful. The Navajos and Apaches retaliated when settlers seized their lands and destroyed their animals and gardens.

On June 19^th, 1848, the Turner heirs won the one of the longest cases in the history of U.S. courts (the Heirs of Henry Turner and the United States.)  The case affirmed them as the lawful owners with good title, securing the land rights of the Emperial Nation forever.  The United States Supreme Court could derive no jurisdiction in the matters of foreign agreements.  Only the laws of Spain could hold jurisdiction over contracts originated and constructed by its sovereign government.  The U.S. desperately tried to coerce the Turner Heirs into relinquishing their claims, which they declined to do.

The U.S. government did not stop there.  After suffering staggering defeats in their own judicial system, the U.S. dispatched agents to exterminate the Turner Heirs.  The period following the court cases saw a campaign of terrorist activity and organized calamities that included wholesales murders, poisoning of the ground waters and sacking of the Washitaw properties.  New laws were hurriedly passed enticing Americans to slaughter the Ancient inhabitants and take their lands.  Eventually, once it was thought all the Washitaw-Turners had been killed, the Supreme Court tried to encourage the lower courts to reverse their rulings in favor of the Turner Heirs, but it was not possible.  The idea of sovereign lands owned by dark-skinned women infuriated the psychopathic racist and sexist Americans.  Fortunately, the Turner women and children were able to escape the genocidal campaigns by hiding in the bayous near the mounds.

When Black Indians in the United States were driven off their land by Europeans, some sought refuge in black communities, passing as 'colored. Africana.com article Indian in the Family explores the topic of black/Indian mixing in the US.

By l860 African Americans had so thoroughly mixed with Native Americans throughout the Atlantic seaboard that white legislators wanted to revoke their tax exemptions. In the Oklahoma Indian Territory 18% of the Cherokees, Choctaws, Chickasaws, Seminoles and Creeks were of African descent. To finally seal off Native American villages and make Indians partners, British merchants introduced Africans as slaves to the Five Nations so to put in the minds of White Indians that all Black Indians were of African descent and thereby divided the Indian people.

In 1860 Indian populations figures over a 30-year period showed a de-cline ranging from 20% to 40%, but the numbers of slaves had increased to 2,5ll for the Cherokees, 2,344 for the Choctaws 1,532 for the Creeks and 975 for the Chickasaws. Slavery had become a major economic factor in each nation.

Whatever unfairness African Americans felt living among Indians, they knew did not compare with what they could expect from southern whites. "The opportunities for our people in that [Indian] country far surpassed any of the kind possessed by our people in the U.S.," wrote Editor O.S. Fox of the Cherokee Afro-American Advocate. His people knew that they lived among Indian men and women who would never brutalize or lynch their sons and daughters.

Indian masters, rejected the worst features of southern white bondage. Travelers reported enslaved Africans "in as good circumstances as their masters." A white Indian Agent, Douglas Cooper, upset by the Native American failure to practice a brutal form of bondage, insisted that Indians invite white men to live in their villages and "control matters."

No less than in the North and South, the Civil War tore Indian nations apart. Surrounded by Confederate troops and influenced by Confederate Indian agents, most Native Americans in Oklahoma felt they had little choice but follow the Confederacy. However, in November 1861 hundreds of black and red Indians led by Creek Chief Opothle Yahola, fought three pitched battles against Confederate whites and Indians to reach Union lines in Kansas, and offer their services. With the defeat of the Confederacy and its Indian allies, northerners sought revenge and the U.S. scrapped existing treaties with Native American nations.

In the 19th century, a number of high ranking Seminoles married black wives - Chief Osceola was one of them. It was said that 52 of his 55 body guards were black. Seminole King Philip too had a black son John Philip, half brother to Chief Wild Cat. King Philip, Chief Osceola and Wild Cat were key figures in the 2nd Seminole war between the US and the Seminole Nation.¹⁰ The US General Sidney Jesup apparently saw the mixing of blacks and Indians in the Seminole Nation as a threat: "... the 2 races ... are identified in interests and feelings...Should the Indians remain in this territory, the negroes among them will form a rallying point for runaway negreos from adjacent states."¹¹  

There are large numbers of black Americans of Native American ancestry.  The first president of Mexico, (Vicente Guerrero and his Black Indian Family) who abolished slavery, was of African, native and Spanish ancestry.

After the Civil war on March 4, 1865 President Abraham Lincoln, in his second Inaugural address, decided emancipate all enslaved Black Indians and those of our brethren the Ebos brought from Africa.  Here he states that: "It may seem strange that any men should dare to ask a just God's assistance in wringing their bread from the sweat of other men's faces, but let us judge not, that we be not judged.  The prayers of both could not be answered.  That of neither has been answered fully.  The Almighty has His own purposes.  "Woe unto the world because of offenses; for it must needs be that offenses come, but woe to that man by whom the offense cometh."  If we shall suppose that American slavery is one of those offenses which, in the providence of God, must needs come, but which, having continued through His appointed time, He now wills to remove, and that He gives to both North and South this terrible war as the woe due to those by whom the offense came, shall we discern therein any departure from those divine attributes which the believers in a living God always ascribe to Him?  Fondly do we hope, fervently do we pray, that this mighty scourge of war may speedily pass away, Yet, if God wills that it continue until all the wealth piled by the bondman's two hundred and fifty years of unrequited toil shall be paid by another drawn with the sword, as was said three thousand years ago, so still it must be said "the judgments of the Lord are true and righteous altogether."

The Seminole nation made the most rapid adjustment to emancipation, electing six Black members to its first post-war governing Council. Black Seminoles began to build homes, churches, schools and businesses. Cherokees and Creeks moved to-ward equality somewhat slower and Choctaws and Chickasaws slower yet.

The Cherokee kept black slaves until 1866, when an emancipation treaty freed them from bondage and granted them full tribal citizenship. Known as the Freedmen, these men and women were embraced by the Cherokee as equals, and often married the offspring of their former masters. Like Stick, they identified with local cultures, spoke tribal languages, and took part in tribal religious rites.

In 1871 Congress decided that Indian tribes were no longer to be recognized as sovereign powers with whom treaties must be made. Although existing treaties were still to be considered valid, violations continued to occur.

In the early months of 1879, an accumulation of circumstances (including the Indian Removal Act and the Emancipation of slaves both Black Indian and Africans) caused approximately 50,000 blacks to migrate to the North, with most of them moving into Kansas, John Brown country.  Benjamin "Pap" Singleton, who called himself "The Moses of the Colored Exodus," reportedly started the migration and led some 300 blacks to Cherokee county, Kansas, to found "Singleton's Colony."

In 1885 Johannes King, an African who lived among the Matawai Indians in Guianas, recalled his peoples struggle to stay alive during decades of warfare: "Here is the story of our ancestors and of their difficulties while they were at war with the bakra [whites].  At that time they suffered severe shortages and were living under dreadful conditions, but the lack of food was their worst problem.  They didn't even have time to clear and plant gardens to produce food.  The whites were always pursuing and attacking…. They slashed the crops to bits, ruining everything they saw.  They set fire to everything they didn't want to carry with them.  Well, that enraged our early ancestors against the whites.

Edwin P. McCabe, who edited the newspaper, The Herald, led a movement to make Oklahoma a state to be governed entirely by blacks.  He devoted his newspaper to this cause, encouraged blacks to organize land purchasing societies, and 25 self-governing all black communities were established there.

Many whites, regarding ownership of land as the basis of success, feared that by owning their own farms the Indians would become independent. Other whites, hungry for land, thought that too much land had already been reserved to the Indians. 

Both groups of whites urged the passage of the Indian General Allotment Act of 1887. This act provided for dividing reservations, which had been held in common by the tribes, into parcels to be allotted to individual Indians. The "surplus" land, in at least one case a larger area than that divided among the Indians, was eventually sold to white homesteaders. Provisions of the act also granted citizenship to the Indians receiving parcels of land and to any other Indians who agreed to give up tribal life for "civilized" ways.   

In 1889 the federal government wanted the land from the Indians for white settlement.  The pressure to open the Indian Territory for white pioneers gradually increased. Finally Congress purchased a tract of 2 million acres (810,000 hectares) for farming in the central part of present Oklahoma. At noon on April 22, 1889, the area was opened to new settlement.  At the same time in 1889 scientist John W. Emmert began to investigate the old home lands of the Creek and Cherokee.  The Smithsonian Institution's Bureau of American Ethnology, in the course of its Mound Survey Project, discovered a small Paleo-Hebrew inscribed stone in an undisturbed burial mound on the Little Tennessee River.  Located at the mouth of Bat Creek, some 40 miles south of Knoxville, Tennessee, the mound was the smallest in a group of three; it measured 28 feet in diameter and 5 feet high.  Emmert also found nine skeletons lay in two parallel rows, with two in one row and seven in the other.  Eight of the skeletons lay with their heads to the north, but one skeleton, in the group of two, lay with its head to the south.  It was under the skull of this particular skeleton that Emmert found the inscribed stone.  This was some of the first archaeological evidence found at the time to prove the link of our people to that of the tribes of Israel. Afterward they sought to investigate the amount of Black Indians from these locations that were there, that they moved to Oklahoma. 

The 1890 census counted 18,636 people "of Negro descent in the Five Tribes." With no ability to speak any Native American language, the clerks often relied on the eyeball test. Those who fit the stereotype - ruddy skin, straight hair, high cheekbones - were placed on the "blood roll." The roll noted each person's "blood quantum," the fraction of their parentage that was ostensibly Native American. That number was sometimes based on documentation, but often, given the lack of accurate records and the language barrier, it was nothing more than crude guesswork.  At this time the Ghost Dance movement was crushed in 1890 with the arrest and murder of Sitting Bull and the massacre by the Army of several hundred Indians at Wounded Knee Creek in South Dakota. This event ended the conquest of the American Indian.
