When was the Republic of Texas formally established?

The Republic of Texas was formally established on May 14, 1836, following the victory at the Battle of San Jacinto, where Texian forces defeated the Mexican army. This date marks the culmination of a struggle for independence from Mexico that began with the Texas Revolution. The declaration of independence was actually made on March 2, 1836, but the official recognition of Texas as a republic was solidified when the terms of surrender were signed by General Santa Anna on May 14. This transition allowed Texas to function as an independent nation until it later joined the United States in 1845.
