Tejanos in the context of "Californio"

The Republic of Texas (Spanish: República de Tejas), or simply Texas, was a sovereign country in North America from March 2, 1836, to February 19, 1846. Texas was bordered by Mexico to the west and southwest, the Gulf of Mexico to the southeast, the two U.S. states of Louisiana and Arkansas to the east and northeast, and U.S. unorganized territory encompassing parts of the current U.S. states of Oklahoma, Kansas, Colorado, and Wyoming to the north. The Texas Revolution began when hostilities broke out on October 2, 1835, shortly before the regime of Mexican President and General Antonio López de Santa Anna adopted a new Mexican constitution known as the Siete Leyes that abolished the authority of the states under the federal republic and established a centralized government. The revolution lasted for over six months. On March 2, 1836, delegates in convention proclaimed the Texas Declaration of Independence. Major fighting ended on April 21, 1836, with the Treaties of Velasco that ended the fighting and secured Texas' independence.

The Mexican Congress refused to recognize the independence of the Republic of Texas, as the Treaties of Velasco were signed by Santa Anna under duress as prisoner. The majority of the Mexican Congress did not approve the agreement. Much of its territory was controlled and disputed by Mexico or the Comancheria; Mexico considered it a rebellious province during its entire existence. The Anglo-American residents of the area and of the republic were referred to as Texians, while Texans of Mexican descent were referred to as Tejanos.

Texians were white American immigrants to Mexican Texas and, later, citizens of the Republic of Texas. Today, the term is used to identify early Anglo settlers of Texas, especially those who supported the Texas Revolution. Mexican settlers of that era are referred to as Tejanos, and American citizens of the modern State of Texas regardless of race and ethnicity are referred to as Texans.

The Battle of the Alamo (February 23 – March 6, 1836) was a pivotal event and military engagement in the Texas Revolution. Following a 13-day siege, Mexican troops under President General Antonio López de Santa Anna reclaimed the Alamo Mission near San Antonio de Béxar (modern-day San Antonio, Texas, United States). About one hundred Texians, wanting to defy Mexican law and maintain the institution of chattel slavery in their portion of Coahuila y Tejas by seeking secession from Mexico, were garrisoned at the mission at the time, with around a hundred subsequent reinforcements led by eventual Alamo co-commanders James Bowie and William B. Travis. On February 23, approximately 1,500 Mexicans marched into San Antonio de Béxar as the first step in a campaign to retake Texas. In the early morning hours of March 6, the Mexican Army advanced on the Alamo. After repelling two attacks, the Texians were unable to fend off a third attack. As Mexican soldiers scaled the walls, most of the Texian fighters withdrew into interior buildings. Those who were unable to reach these points were slain by the Mexican cavalry as they attempted to escape. Almost all of the Texian inhabitants were killed.

Several noncombatants were sent to Gonzales to spread word of the Texian defeat. The news sparked both a strong rush to join the Texian army and a panic, known as "The Runaway Scrape", in which the Texian army, most settlers, and the government of the new, self-proclaimed but officially unrecognized Republic of Texas fled eastward toward the U.S. ahead of the advancing Mexican Army. Santa Anna's execution of surrendering soldiers during the battle inspired many Texians and Tejanos to join the Texian Army. The Texians defeated the Mexican Army at the Battle of San Jacinto, on April 21, 1836, ending the conquering of the Mexican state of Coahuila y Tejas by the newly formed Republic of Texas.

Tex-Mex cuisine (derived from the words Texas and Mexico) is a regional American cuisine that originates from the culinary creations of Tejano people inspired in Mexican culinary traditions. It has spread from border states such as Texas and others in the Southwestern United States to the rest of the country. It is a subtype of Southwestern cuisine found in the American Southwest.

The Hispanos of New Mexico (New Mexican Spanish: Neomexicanos or Nuevomexicanos), or commonly New Mexican Hispanics, are a Hispanic ethnic group originating in the historical region of Santa Fe de Nuevo México, today the US state of New Mexico (Nuevo México), southern Colorado, and other parts of the Southwestern United States including Arizona, Nevada, Texas, and Utah. They are descended from Oasisamerica groups and the settlers of the Viceroyalty of New Spain, the First Mexican Empire and Republic, the Centralist Republic of Mexico, and the New Mexico Territory.

The descendants of these New Mexican settlers make up an ethnic community of approximately 340,000 in New Mexico, with others throughout the historical Spanish territorial claim of Nuevo México. Alongside Californios and Tejanos, they are part of the larger Hispanic community of the United States, who have lived in the American Southwest since the 16th century. These groups are differentiated by time period from the population of Mexican Americans that arrived after the Mexican–American War and later Mexican Revolution. They also differ genetically in their Indigenous heritage, as Mexican Americans tend to be more related to Mesoamerican groups, whereas New Mexicans are more often related to Oasisamerican Indigenous peoples of the North American Southwest.
