Viceroyalty of New Spain. Later, France also
claimed the area but never established much settlement.
In 1819, the
Adams-Onís Treaty between the United States and Spain defined the
Red River as the northern boundary of
New Spain, officially placing the future location of Dallas well within Spanish territory.
 The area remained under Spanish rule until 1821, when Mexico declared independence from Spain, and the area was considered part of the Mexican state of

The gunman, later identified as Micah Xavier Johnson, began firing at police officers at 8:58 p.m., killing five officers and injuring nine. Two bystanders were also injured.
