The Mexican populations during these years are referred to as Tejano. The word Tejano is defined in the Handbook of Texas Online as: a Texan of Mexican descent, thus a Mexican Texan or a Texas Mexican. Two main elements defined Tejano life and culture during this period of time. First, all Tejanos shared a military background which developed into a strong sense of mission to defend Mexico's northern frontera (Tejano Origins in Mexican Texas) and, secondly, by the distinct racial mixture that set Tejano people apart from the Anglo American colonists who arrived in 1821. In 1821 there were three distinct and separate Tejano settlements: the Nacogdoches region, the Béxar-Goliad region and the Río Grande ranching frontier. Political unrest and the United States' desire to annex Texas led to the confrontations and battles that resulted in, first, Texas' independence from Mexico, and then the United States annexation of Texas. 1810 Miguel Hidalgo, a Mexican Priest, begins a movement that ultimately leads to Mexico's independence from Spain. 1821 Austin's 300 arrive in Texas 1821 Mexico wins its independence from Spain 1832 Battle of Nacogdoches 1833 Santa Anna establishes a dictatorship in Mexico 1835 Siege of Béxar, first major campaign of the Texas Revolution 1835 Goliad Declaration of Independence 1836 The Battle of the Alamo; Texas wins its independence from Mexico 1836 Treaties of Velasco 1842 Mexican Invasions of Texas 1845 United States annexes Texas 1846 Beginning of Mexican War 1848 Treaty of Guadalupe Hidalgo ends Mexican War The Portal to Texas History Tejano in The Handbook of Texas Mexican Government of Texas in The Handbook of Texas Nacogdoches, Texas in The Handbook of Texas Goliad, Texas in The Handbook of Texas Battle of Nacogdoches in The Handbook of Texas Siege of Béxar in The Handbook of Texas Goliad Declaration of Independence in The Handbook of Texas Miguel Hidalgo in The Handbook of Texas Moses Austin in The Handbook of Texas Antonio López De Santa Anna in The Handbook of Texas The Battle of the Alamo in The Handbook of Texas Republic of Texas in The Handbook of Texas Treaties of Velasco in The Handbook of Texas Mexican Invasions of 1842 in The Handbook of Texas Mexican War in The Handbook of Texas Treaty of Guadalupe Hidalgo in The Handbook of Texas Ranching in The Handbook of Texas Treaty of Velasco
