On December 18, 1865 in the United States.
"The war ended on June 22, 1865, and after that surrender, the Proclamation of Emancipation was applied in all the remaining regions of the South that had not yet freed the slaves." Slavery officially continued for a couple of months in others. Federal troops arrived in Galveston, Texas, on June 19, 1865, to enforce emancipation.That day of gaining freedom in Texas is now celebrated as Juneteenth in many states of the United States.
The Thirteenth Amendment, which abolished slavery, except as punishment for a crime, had been approved by the Senate in April 1864 and by the House of Representatives in January 1865. The amendment did not come into force until it was ratified by three quarters of the states. that happened on December 6, 1865, when Georgia ratified it. On that date, all remaining slaves became officially free.
Legally, the last 40,000-45,000 slaves were released in the last two slave states of Kentucky and Delaware through the final ratification of the Thirteenth Amendment to the Constitution on December 18, 1865. The slaves are still in Tennessee, Kentucky, Kansas, New Jersey, Delaware, West Virginia, Maryland, Missouri, Washington, DC and twelve Louisiana parishes also became legally free on this date. "

But slavery persisted in the "Indian territories" for another six months.
"The problem is that the Indian territory was not within the" jurisdiction "of the United States as that term was understood in the 1860s. Since the United States government used the international treaty law device to treat With all the Indian tribes, even the civilized Tribes, the Lincoln Administration continued the practice of treating the Indian tribes as if they were separate sovereigns, outside the jurisdiction of the United States.
The Fourteenth Amendment, promulgated in Congress the following year, had a similar disclaimer: "All persons born or naturalized in the United States, and subject to their jurisdiction, are citizens of the United States …" , which provided a continuing foundation for treating Native tribal Indians born as noncitizens.
In fact, in 1866, the United States addressed the issue of slavery in Indian territory by entering into new treaties with each of the civilized tribes (although the treaty with Choctaw and Chickasaw was a joint treaty). Until these treaties, signed between March and July and proclaimed in July and August, only the Cherokees had taken measures to abolish slavery. However, in each treaty of 1866, the tribal signatory recognized that slavery would no longer be recognized as a legal institution by the tribe.
If we limit ourselves to the dates on which the tribes ratified these treaties, slavery in the continental United States came to an end as a legal institution on June 14, 1866, when the Creek tribe agreed to abandon African-American slavery. It was, somewhat ironically, the day after Congress passed the Fourteenth Amendment. "
