Excerpts from Books and Wikipedia
"In the 1960s, Malcolm X began to grow disillusioned with the Nation of Islam, and in particular, with its leader Elijah Muhammad. Expressing many regrets about his time with them, which he had come to regard as largely wasted, he instead embraced Sunni Islam. Malcolm X then began to advocate for racial integration and disavowed racism after completing Hajj, whereby he also became known as el-Hajj Malik el-Shabazz. After a brief period of travel across Africa, he notably repudiated the Nation of Islam, and founded Muslim Mosque, Inc. (MMI) and the Organization of Afro-American Unity (OAAU) to emphasize Pan-Africanism. . . . Throughout 1964, his conflict with the NOI [Nation of Islam] intensified, and on February 21, 1965, he was assassinated by three of its members. Malcolm X Day is celebrated in various cities and countries worldwide, and hundreds of streets and schools in the U.S. are named in his honor." [Wikipedia]
