Explanation:

The most infamous forced relocation is known as the Trail of Tears where Cherokee, Creek, Chickasaw, Choctaw, Seminole and other native American nations were forced out of their ancestral land because members of the US government believed that their land was needed for agriculture. The best way they figured out to get the land was to expel their rightful owners using force.

Even though native Americans had suffered so much in the previous decade (1830s), the Choctaw Nation donated $170 (equivalent to $5,000 today) to the Irish during the great Irish famine. Many Irish farmers lost their potato crops and many people in Ireland were starving to death. Irish descendants still remember the generosity of the Choctaw Nation even in times when they themselves were suffering a lot.
