Upon removing Spanish control in Cuba, what did the United States place on the island that is still in existence today?

The AIM chose Wounded Knee, South Dakota, for their protest occupation in 1973 because of its emblematic character, since there had been a bloody battle almost a century before that supposed the definitive end of the indigenous resistance.

Explanation:

The reason for the protest was the accusation made against Richard Wilson, the tribal president, to whom they attributed corruption cases, as well as publicly making public his complaint about the continued delay by the government in the practical development of the treaties.

To all that was added the miserable economic situation of the reserve, where the Indians owned the land but its use depended in part on the executive and it was slow to pay agricultural leases to settlers, in addition to imposing the mining use of a important part, giving it to private companies.
