To celebrate Texas Independence Day, the UT Tower will shine with orange lights Friday, March 2.

The holiday commemorates the adoption of the Texas Declaration of Independence and formation of the Republic of Texas in 1836.

“For the proudest of Texans, it’s the most important day of the year,” says Jim Nicar, who studies the university’s history. “It’s a holiday that no other state can claim.”

The Tower’s entirely orange lighting configuration used to mark Texas Independence Day is reserved for special occasions like the university’s birthday on Sept. 15, when a Texas Athletics team wins a Big 12 Championship, commencement, Academic Convocation, and Honors Day, among others.

As Nicar noted, the Texas Exes adopted a resolution in 1900 to remind Longhorns to celebrate both the Lone Star State and the university. It reads:

Whenever two Texas Exes shall meet on March 2, they all shall sit and break bread and pay tribute to the institution that made their education possible.

Happy Texas Independence Day, Longhorns!
