What event is associated with the declaration of Independence for Texas?

The declaration of independence for Texas is most closely associated with the Capture of San Antonio in 1835. This event is significant because it marked a turning point in the Texas Revolution against Mexican rule. Following this capture, Texian forces gained control of San Antonio, which was a strategic victory that emboldened those advocating for independence. The success of the rebels there galvanized support for the independence movement, leading to the subsequent declaration of independence on March 2, 1836.

While other options represent important events in Texas history, they do not directly correlate with the declaration of independence. For example, the Battle of Medina was a conflict that occurred earlier in 1813 and did not pertain to Texian independence. The Treaty of Cordoba in 1821 ended Spanish rule in Mexico, a different historical context, and James Long's execution in 1822 relates to early attempts at Texan independence but does not represent a defining moment in the declaration itself. Understanding the significance of the Capture of San Antonio highlights its crucial role in shaping the movement for Texian independence.
