When Texans talk about the Declaration of Independence, they usually mean the one signed at Washington-on-the-Brazos on March 2, 1836. Occasionally, we refer to the Goliad declaration of 1835. But there was one before all of them. In 1813, Texans in San Antonio de Bexar declared the province of Texas to be independent. The wording sounds familiar in places but the principals are timeless, and very familiar to Texans and Americans. Learn more about what motivated the Texans of 1813 to declare independence, which ultimately led to the Battle of Medina a few months later. (PHOTO BY BOB OWEN/SAN ANTONIO EXPRESS-NEWS/ZUMA PRESS)
