AUSTIN, Texas -- The Bullock Texas State History Museum will display the original American copy of the Adams-Onís Treaty on loan from the United States National Archives.

• Treaty is from the 19th century
• Part of Becoming Texas: Our Story Begins Here exhibition
• Opens December 10

The treaty will be featured in the Bullock Museum's new exhibition, Becoming Texas: Our Story Begins Here, which opens December 10 and lasts until April 30, 2019.

The treaty was signed on February 22, 1819 by Secretary of State John Quincy Adams and Spanish minister Luis de Onís. The treaty gave Florida to the United States and established the Sabine River as the border between the U.S. and New Spain. This borderline formed the northern and eastern boundaries of Texas, establishing the state's famous shape as we know it today.
