"The Iroquois Confederacy comprises six nations: the Mohawk,
Oneida, Onondaga, Cayuga, Tuscarora, and Seneca, whose historical territory is
Upstate New York. In 2005, the Onondaga filed a lawsuit against New York State,
the city of Syracuse, Onondaga County, and five corporations, claiming that the
state had illegally seized the tribe's land and that the corporations had been
destroying the environment in the area." "Part of the problem with the land
rights struggle is the Doctrine of Discovery, which states that European
explorers and settlers have superior rights to the land. This doctrine flows
from a decree by Pope Nicholas in 1452 to allow the subjugation of "heathen"
lands in Africa and the New World. It was adopted by American law in 1823 in the
Supreme Court case Johnson vs. McIntosh, and never overturned." (thanks Amir)
