1806 – 1821
The Lawless Borderland: The Neutral Strip
Following the 1803 Louisiana Purchase, a fierce border dispute erupted between the United States and Spain. To avert war, General James Wilkinson and Lt. Col. Simón de Herrera created the Neutral Ground in 1806, a demilitarized zone stretching between the Sabine River and the Arroyo Hondo. Lacking law enforcement or government control, this strip became a notorious "No Man's Land"—a haven for outlaws, pirates, runaways, and pioneers. The lawlessness persisted until the Adams-Onís Treaty of 1819 (ratified in 1821) firmly established the Sabine River as the U.S. border.
