At the center of this increased Islamic extremism was the Ayatollah Ruhollah Khomeini. "Ayatollah" is the title for a Shiite Muslim religious leader. The Shia branch of the Muslim faith is the dominant religious group in Iran. The Islamic Revolution, inspired by Khomeini, ousted the shah of Iran from power. The shah was a political leader who had been supported by the United States.</span>
I think it is because, during that time there was no place the Africans Americans could go without people treating them badly. I the Northern states slavery was not a thing, so the african americans were free but they were not given the same rights as white people. Many did not want them to have rights because they thought that the african americans would change the government and outcome of elections. White people would make rules like the literary test to insure that african americans would not be able to vote.
hope this helps you!
