Effect: Death of 2 continents. Deconstruction of thriving civilisations. 2 brand new continents for Europeans to put to use.
Cause: The Spaniards wondering if the Earth is actually round. During the journey the stumble upon the New World. Another cause is the greed and disrespect of the Spanish colonizers. The American natives were seen as primitive and savage, which the Spanish saw as a reason/excuse for killing their cities, people and culture.
Answer:
Even as the Supreme Court ruling prohibited it, Cherokees were still removed by the government.
Explanation:
The United States Supreme Court considered that Amerindian tribes were sovereign nations (Cherokee Nation v. Georgia, 1831), and that state laws could not apply to these tribes (Worcester v. Georgia, 1832). President Jackson was deemed, probably wrongfully, to have responded to these convictions: "Marshall made a decision, so let him enforce it." But it is clear that he did not defend the tribes against the decisions of the different states.
The government first negotiated, but only a small part of the people concerned were ready to go hundreds of kilometers to settle on a reserve. It was the American army that finally led a real deportation of the Amerindians, with preliminary gatherings in forts, concentration in large camps and convoys.
This deportation, particularly brutal, took place on forced marches. Thousands of Amerindians died throughout the course, especially among the Cherokee. This displacement became known as the Trail of Tears.
They are more commonly known as the bill of rights.
