What is the significance of the Texas Declaration of Independence?

The Texas Declaration of Independence is significant because it formally declared Texas' independence from Mexico. This declaration, adopted on March 2, 1836, was a pivotal moment in Texas history as it asserted the right of Texans to govern themselves away from Mexican rule. The declaration laid the groundwork for the establishment of the Republic of Texas, allowing it to function independently until it later joined the United States. This event marked a critical turning point in the struggle for autonomy and reflected broader themes of self-determination that were prevalent in many independence movements of the time.

The other options, while related to Texas history, do not reflect the primary significance of the declaration itself. It does not establish Texas as a U.S. territory or create the first state constitution; those occurred later. Additionally, while Texas did later form alliances, particularly during its fight for independence, the declaration itself was primarily focused on asserting independence rather than forming military alliances.
