<span>The Indian Removal Act had many long lasting effects. First, to enforce the Indian Removal Act, Andrew Jackson would have to diobey a direct order from the Supreme Court. Andrew Jackson went through with it anyway and forced the Native Americans to leave their home. I think that had a long lasting effect on the Supreme Court. When people saw that Jackson, the president, didn't care about what the Supreme Court issued then they wouldn't either. The Supreme Court must have been powerless for a long time because of Jackson. Also it was very unfair to the Native Americans. People forget that the land belonged to the natives long before the settlers showed up. To make the many native people move from their homeland isn't right. Still, they had to walk the trail of tears where thousands of natives died from starvation, diesease, and other factors. When people saw how the Native Americans were being forced away the might have decided that the Native Americans were savage. They became afraid of the Native Americans and pressured the federal government to bother the natives more. </span>
