High Quality Content by WIKIPEDIA articles! Aboriginal title in New York has been the source of many disputes regarding the status of aboriginal title in the United States. The European purchase of lands from indigenous populations dates back to the legendary Dutch purchase of Manhattan in 1626, "the most famous land transaction of all." More than any other state, New York disregarded the Confederation Congress Proclamation of 1783 and the Nonintercourse Acts of 1790, 1793, 1796, 1799, 1802, and 1834, purchasing the majority of the state directly from the Iroquois nations without federal involvement or ratification.
