Juan Nepomuceno Seguín (1806–1890) was the leading Mexican-Texan military figure of the Texas Revolution (1835–1836) to participate on the Texas side of the struggle. He was the only Mexican Texan to serve in the Senate of the Republic of Texas and was the last Mexican Texan to serve as mayor of San Antonio until the 1980s. Having fled to Mexico to avoid violence at the hands of enemies he made during his tenure as mayor, he commanded an auxiliary cavalry company of fellow Mexican-Texan exiles in the Mexican army until the end of the US-Mexico War. During his effort to reestablish himself in Texas in the 1850s he wrote his memoirs of the Texas Revolution. He was one of only three Mexican Texans to do so, and the only one to have them published during his lifetime. Seguín returned to Mexico on the eve of the US Civil War to participate in Mexico’s civil conflicts. In about 1870 he permanently settled in Nuevo Laredo, where he died in 1890.
