The GLO’s copy of the Adams-Onís Treaty
“The Texas Society DAR is proud to financially support the translation, transcription, conservation, and preservation of these important documents. These projects align perfectly with our mission areas of historic preservation, education, and patriotism,” said Susan Johnston, Texas State Regent, Texas Society Daughters of the American Revolution. “The Adams-Onís Treaty established the United States as a transcontinental power, while the Expediente No. 59 will illuminate the lives of Tejano ranchers and also provide a rich source of genealogical information.”

A close up of the GLO’s copy of the Adams-Onís Treaty
The Adams–Onís Treaty, a landmark 1819 agreement between the United States and Spain, helped define Texas’s boundaries and shaped the geopolitical landscape of the American Southwest. Under the terms of the treaty, Spain ceded Florida to the United States, while the United States recognized the Sabine River as the eastern boundary of New Spain, thereby relinquishing its claims to Spanish Texas. Unlike most documents in the Spanish Collection, the GLO’s copy of the treaty has never received conservation treatment, contributing to its current deteriorated condition. Conservation of the treaty is therefore essential to ensure its long-term preservation and continued access for researchers and the public.

Additionally, the Spanish Collection document, Expediente No. 59, offers a rare window into the experiences and voices of ordinary Tejano ranchers in 1770s San Antonio. It captures their stories through both collective petitions and individual affidavits
