The results of the Puritan and Glorious Revolutions in England were significant for Europe and the Americas because they demonstrated that Government power was limited by law.
The options to your Question are:
a) Saturday Night Massacre
b) Executive Privilege Firings
c) Nixon Cover-Up
d) Watergate Scandal
The correct answer is Option a. Saturday Night Massacre refers to President Nixon's order to fire several of his staff members who refused to follow his orders. The exact origin of this phrase could not be tracked but it first appeared in an Article of Washington Post two days following the event and the author of that article stated in the article that the event was already being termed as Saturday Night Massacre.
American Indians occupied Alcatraz Island in 1969 as a show of protest against the United States's constant choice to overlook or misrecognize rights and responsibilities set by treaties between tribes and the US government. Additionally (and more importantly) it was a retaliation against the theft of tribal land by the federal government. Protesters believed that if the federal government could illicitly occupy tribal lands, tribal members could just the same occupy federal lands.
The Occupation of Alcatraz was led by the Indians of All Tribes (IAT) as a form of inter-tribal solidarity. It preceded the more famous occupation of Wounded Knee in South Dakota during the early 1970s. That protest was organized primarily by the American Indian Movement (AIM).
