Melchor Ocampo (5 January 1814 – 3 June 1861) was a Mexican lawyer, scientist, and politician. A mestizo and a radical liberal, he was fiercely anticlerical, perhaps an atheist, and his early writings against the Catholic Church in Mexico gained him a reputation as a leading liberal thinker.[1] Ocampo has been considered the heir to José María Luis Mora, the premier liberal intellectual of the early republic.[2] He served in the administration of Benito Juárez and negotiated a controversial agreement with the United States, the McLane-Ocampo Treaty. The Mexican state where his hometown of Maravatío is located was later renamed Michoacán de Ocampo in his honor.
