“Erasmo Seguin”
by Robert Stafford

Erasmo Seguin held many political positions while Texas was under Mexican control, and continued his government involvement when Texas gained independence. Juan Jose Maria Erasmo de Jesus Seguin was born on May 26, 1782 to Santiago Seguin and Maria Guadalupe Fuentes. Seguin married Josefa Augustina Becarra and the couple had four children, the most famous of which was Juan N. Seguin, who became famous in the struggle for Texas independence. Erasmo Seguin became postmaster of San Antonio in 1807 and would hold this position, with few interruptions, until 1835. He was briefly removed as postmaster in 1813 because he was suspected of supporting revolutionaries in the Gutierrez-Magee expedition. He was exonerated in 1818 and regained his position as postmaster in 1822. Seguin also helped found the first public school in San Antonio in 1812. He was elected as the first Alcalde (mayor) of Bexar in 1820.

One of the most important actions Seguin performed was notifying Moses Austin that his petition for a colony in Texas had been accepted in 1821. Seguin formed a personal friendship with Stephen F. Austin during this period, which would continue on for the rest of his life. He also served as the deputy for Texas in the National Congress of Mexico from 1823 to 1824. Seguin also served as a Texas representative to the Mexican Congress that wrote the Constitution of 1824, creating a constitutional government in Texas. He worked for Texas' recognition as a state, but reluctantly accepted the union of Coahuila and Texas.

After General Santa Anna came to power, Seguin and others sent the “San Antonio Remonstrances” in 1832 to protest his becoming a dictator. Seguin also organized an opposition convention to Santa Anna in 1834. For his revolutionary actions, General Martin Perfecto de Cos removed Seguin from his role as postmaster and forced him to leave San Antonio on foot. Seguin used this opportunity to recruit men to his house to help win the siege of Bexar in December 1835. Seguin also sent provisions to the Alamo before the final siege and housed David Crockett in his home for awhile.

Since he was a key member of the revolution and development of Texas, Erasmo Seguin was named a Chief Justice of Bexar County on December 18, 1837. He would hold this position until January 9, 1840. After leaving this position, he mostly secluded himself to his Casa Blanca Ranch, where he died in 1857.
