U.S. labour union. Founded in 1890, the UMWA grew rapidly under the leadership of John Mitchell (president 1898-1908) despite determined opposition from coal-mine operators. By 1920, when John L. Lewis took over, the union had half a million members. Lewis capitalized on the pro-labour climate of the New Deal and led numerous strikes to win fair pay, safe working conditions, and benefits.
