Henry Moore, politician, was born a slave in Alabama around 1810. He may have purchased his freedom before he arrived in Texas about 1842. He was a farmer when he was elected to the Twelfth and Thirteenth legislatures in predominantly black Harrison County. During the Twelfth Legislature (1870) Moore served on the Militia Committee in the House of Representatives and displayed an interest in public school legislation. In the Thirteenth Legislature (1873) he sat on the Roads, Bridges, and Ferries Committee and supported legislation to establish the Hallsville Masonic Institute of Harrison County. Moore lost an election for the state Senate in 1880. He had a wife named Harriet and three daughters in 1870. The 1880 federal census reported Moore's occupation as gardener. He does not appear on census reports for Harrison County after 1880.
