Treaties of Velasco in the context of "Texian Militia"

The Mexican–American War, also known in the United States as the Mexican War and in Mexico as the United States intervention in Mexico, (April 25, 1846 – February 2, 1848) was an invasion of Mexico by the United States. It followed the 1845 American annexation of Texas, which Mexico still considered its territory because it refused to recognize the Treaties of Velasco, signed by President Antonio López de Santa Anna after he was captured by the Texian Army during the 1836 Texas Revolution. The Republic of Texas was de facto an independent country, but most of its Anglo-American citizens who had moved from the United States to Texas after 1822 wanted to be annexed by the United States.

Sectional politics over slavery in the United States had previously prevented annexation because Texas would have been admitted as a slave state, upsetting the balance of power between Northern free states and Southern slave states. In the 1844 United States presidential election, Democrat James K. Polk was elected on a platform of expanding U.S. territory to Oregon, California (also a Mexican territory), and Texas by any means, with the 1845 annexation of Texas furthering that goal. However, the boundary between Texas and Mexico was disputed, with the Republic of Texas and the U.S. asserting it to be the Rio Grande and Mexico claiming it to be the more-northern Nueces River. Polk sent a diplomatic mission to Mexico in an attempt to buy the disputed territory, together with California and everything in between for $25 million (equivalent to $798 million in 2024), an offer the Mexican government refused. Polk then sent a group of 80 soldiers across the disputed territory to the Rio Grande, ignoring Mexican demands to withdraw. Mexican forces interpreted this as an attack and repelled the U.S. forces on April 25, 1846, a move which Polk used to convince the Congress of the United States to declare war.

The Texian Army, also known as the Revolutionary Army and Army of the People, was the land warfare branch of the Texian armed forces during the Texas Revolution. It spontaneously formed from the Texian Militia in October 1835 following the Battle of Gonzales. Along with the Texian Navy, it helped the Republic of Texas win independence from the Centralist Republic of Mexico on May 14, 1836 at the Treaties of Velasco. Although the Texas Army was officially established by the Consultation of the Republic of Texas on November 13, 1835, it did not replace the Texian Army until after the Battle of San Jacinto.

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.

Surfside Beach, also known locally as Surfside, is a city in Brazoria County, Texas, United States, that is situated on Follet's Island by the Gulf of Mexico near the city of Freeport. The population was 640 at the 2020 census. The city has claimed the "Cradle of Texas Liberty" title due to the fact that the Treaty of Velasco which ended hostilities between Texas and Mexico was signed at Fort Velasco, which was located near the city's current City Hall.

Former Congressman Ron Paul maintained a home near Surfside Beach before selling it on Facebook in 2011.

The Texian Navy, also known as the Revolutionary Navy and First Texas Navy, was the naval warfare branch of the Texian armed forces during the Texas Revolution. It was established by the Consultation of the Republic of Texas on November 25, 1835. Along with the Texian Army, it helped the Republic of Texas win independence from the Centralist Republic of Mexico on May 14, 1836 at the Treaties of Velasco. It was replaced by the Texas Navy on March 23, 1839.
