Martin Luther King Jr.
The first march was on March 7, 1965.  Police officers, and people they had chosen to help them, attacked the marchers with clubs and tear gas.  They threatened to throw the marchers off the Edmund Pettus Bridge.  Seventeen marchers had to go to the hospital, and 50 others were also injured.  This day came to be called Bloody Sunday.  Pictures and film of the marchers being beaten were shown around the world, in newspapers and on television.  Seeing these things made more people support the civil rights activists.  People came from all over the United States to march with the activists.  One of them, James Reeb, was attacked by white people for supporting civil rights.  He died on March 11, 1965.
