She was born the 20th child in a family that had lived in the Mississippi Delta for generations, first as enslaved people and then as sharecroppers. She left school at 12 to pick cotton, as those before her had done, in a world in which white supremacy was an unassailable citadel. She was subjected without her consent to an operation that deprived her of children. And she was denied the most basic of all rights in America<U+2015>the right to cast a ballot<U+2015>in a state in which Blacks constituted nearly half the population. And so Fannie Lou Hamer lifted up her voice. Starting in the early 1960s and until her death in 1977, she was an irresistible force, not merely joining the swelling wave of change brought by civil rights but keeping it in motion. Working with the Student Non-Violent Coordinating Committee (SNCC), which recruited her to help with voter-registration drives, Hamer became a community organizer, women's rights activist, and co-founder of the Mississippi Freedom Democratic Party. She summoned and used what she had against the citadel<U+2015>her anger, her courage, her faith in the Bible, and her conviction that hearts could be won over and injustice overcome. She used her brutal beating at the hands of Mississippi police, an ordeal from which she never fully recovered, as the basis of a televised speech at the 1964 Democratic Convention, a speech that the mainstream party<U+2015>including its standard-bearer, President Lyndon Johnson<U+2015>tried to contain. But Fannie Lou Hamer would not be held back. For those whose lives she touched and transformed, for those who heard and followed her voice, she was the embodiment of protest, perseverance, and, most of all, the potential for revolutionary change.
