San Antonio is the third-largest city in Texas. It is located in the south-central part of the state, on the bank of San Antonio River.
San Antonio first visited the city in 1691 on the feast day of St. Anthony.Therefore the city was named San Antonio de Padua in his honor. San Antonio remained under Spanish rule until 1812, when Mexico won its independence from Spain.
During the outbreak of the Texas revolution (1835) against the tyranny of Mexican dictator General Santa Anna, San Antonio was captured by a small band of rebels who occupied the fortified mission of the Alamo in Dec. 1835. The historic battle of the Alamo was fought there (Feb. 24 to March 6, 1836), and its 183 besieged defenders were massacred by Santa Anna's troops. Their heroism aroused the anger and fighting spirit of Texans and led them to shout their famous battle cry “Remember the Alamo!” and defeat the Mexicans six weeks later (April 21, 1836) at the battle of San Jacinto. Texas became an independent republic in 1836, and San Antonio was incorporated as a city on Jan. 5, 1837.
