José Antonio Navarro became a representative in the Republic of Texas Congress from Bexar County, Texas. Attempting to keep a balance of power, he worked closely with Senator Juan Seguin to promote legislation favorable to the Tejano citizenry, who were quickly becoming the political minority. Education was one such priority, working to bring academic institutions into the San Antonio area. He supported the annexation of Texas by the United States. In 1845, Navarro was instrumental in drafting the first state Constitution of Texas, ensuring future political rights for all people. He served two terms in the Texas Senate before temporarily retiring from politics in 1849.
