(nyt) Imari Obadele, a teacher and writer whose commitment to black empowerment fired a militant, sometimes violent effort to win reparations for descendants of slaves and to carve out, however quixotically, an African-American republic in the Deep South, died on Jan. 18 in Atlanta. He was 79. The cause was a stroke, said Johnita Scott, his former wife. Mr. Obadele (pronounced oh-ba-DEL-ee) was president of what he called the Republic of New Afrika, a country that existed as an idea. His provocative proposal was to have Alabama, Georgia, Louisiana, Mississippi and South Carolina — the heart of the old Confederacy — removed from the union and given over to black Americans. The demand drew the national news media’s attention. The New York Times called it “bizarre.” The proposal emerged in 1968, the year the Rev. Dr. Martin Luther King Jr. was assassinated. Black separatism was on the rise, with some advocates resurrecting 19th-century proposals for blacks to return to Africa. Mr. Obadele, who had despaired of integration into white society, demanded American land as payback for the centuries of abuse blacks had suffered. He also asked for billions of dollars and became a leader of the reparations movement.
