Editing Costilla County, Colorado (section)

==History==

On July 8, 1694, Spanish Conquistador [[Don Diego de Vargas]] and his army, two weeks before the Battle of [[Astialakwa]], reached Costilla County. Diego Vargas is not the first Spaniard in Colorado. Juan de Archuleta led an expedition into Colorado in 1664 - but his expedition is the first traceable Spanish expedition into Colorado.<ref name="Espinosa">Espinosa, J. Manuel.

While Rosa came near Colorado, it has not been verified he actually did.

Costilla County was the first area of Colorado to have been colonized. The county made up the major part of the [[Sangre de Cristo Land Grant]] awarded by the government of New Mexico to the [[Carlos Beaubien]] family in 1843.

[[San Miguel, New Mexico Territory|San Miguel]] was originally designated the county seat, but the county government was moved to San Luis in 1863. (In 1869, surveys placed San Miguel in the [[New Mexico Territory]].)

The county's original boundaries extended over much of south-central Colorado. Much of the northern portion became part of [[Saguache County]] in 1866, and the western portions were folded into [[Hinsdale County, Colorado|Hinsdale]] and [[Rio Grande County, Colorado|Rio Grande]] counties in 1874. Costilla County arrived at its modern boundaries in 1913 when [[Alamosa County, Colorado|Alamosa County]] was created from its northwest portions.<ref>Pages 242-247, Bauer, William H.; Ozment, James L.; and Willard, John H., ''Colorado Post Offices, 1859-1989: A Comprehensive Listing of Post Offices, Stations, and Branches'', Colorado Railroad Museum (May 1990), hardcover, 280 pages, {{ISBN|978-0-918654-42-7}}</ref>
