What was the supreme court's decision in plessy v. ferguson? what effect did this decision have?

In Plessy v Ferguson (1896), the Supreme Court upheld the legality of segregated public facilities based upon race.

This led to the policy of "separate but equal" which meant that throughout the United States, public and private organizations were able disallow people of color from schools and bathrooms as long as they had separate facilities for people of color.

in which two ways were the northeast woodland indians and the southeast indians similar? both collaborated to form the iroquois confederacy. both cultivated the crops of corn, beans, and squash. both lived in rich environments of swamps and rivers. both lived in tree-bark dwellings called wigwams. both expected men to hunt, while women farmed.
