The complex political environment that emerged in Canada with the Haudenosaunee was born from the Anglo-American era of European colonization. At the end of the War of 1812, Britain transferred Indian affairs from military control to civilian control. With the creation of the Canadian Confederation in 1867, civil authorities and thus Indian affairs were transferred to Canadian officials, with Britain expected to retain control over military and security matters. At the turn of the century, the Canadian government began to pass a series of laws hotly contested by the Iroquois Confederation. During the First World War, an act attempted to enlist six-nation men into the army. A law on the redistribution of Urland was introduced as a result of the law on the regulation of reissue. Finally, in 1920, legislation was proposed to impose citizenship on “Indians,” with or without their consent, who would automatically remove their share of tribal areas from tribal trust and subject the country and the person to Canadian law.  The Iroquois were also concerned about the settlers. The British asked for the support of the Iroquais during the war. In 1775, the Continental Congress sent a delegation to the Iroquais in Albany to demand their neutrality in the war against the British.
 In previous years, it was clear that the settlers had not complied with the land agreements of 1763 and 1768. The Iroquois Confederacy was particularly concerned about the possibility of the settlers winning the war, for if there were to be a revolutionary victory, the Iroquois saw them as forerunners of their countries, abducted by the victorious settlers who would no longer have the British crown to hold them back.  Continental Army officers such as George Washington had attempted to destroy the Iroquois.  The five nations of the Confederacy Haudenosaunee – also known as the Iroquois League or League of Five Nations – occupied an area from the Genesee River in the west to the Hudson River in the east in the eastern Woodland cultural area. In 1722, the linguistically related Tuscarora moved north from North Carolina and Virginia to join the Confederacy. Although technically the sixth nation of the Confederacy, the Tuscarora – along with other represented nations such as Delaware, Wyandot and Tutelo – present their problems to the Confederacy through the Cayuga Nation. Inevitably the slavery of the Haudenosaunee changed after the European contact. With the arrival of European diseases came the increase of hedosaune populations, which received prisoners, as their population continued to decrease.   In the 17th century, the Haudenosaunee peoples united to oppose the settlers.
 At the end of the century, the population of Haudenosaunee was composed mainly of prisoners from other nations.  Among the indigenous groups targeted by the Haudenosaune were the Wyandot, captured in such large numbers that they lost their independence for a long time.   Funeral wars became indispensable to the reconstruction of numbers, but also haudenosaunee warriors began to target French and later English colonizers.   Like native slaves, European slaves were tortured by the haudenosaunee with finger mutilation and sometimes cannibalism.  European prisoners did not make good slaves because they were even more opposed as indigenous prisoners and did not understand rituals such as the change of fame and forgetting their past.  This is why most European prisoners were either used as ransom or murdered upon arrival in Haudenosaunee.  However, many Europeans were not captured, but became trading partners of the Haudenosaunee.  Native slaves were traded among European settlers and some slaves even ended up in Quebec households.  Finally, European contact led the adoptive parents to overtake the Haudenosaunee in their own communities, these slaves were too difficult to control, and so came the definitive end of Haudenosaunee`s slavery practices.  1.
