HELP ASAP IM MAKING AN ESSAY To what extent did the relationship between Spain and Texas change
between 1519 and 1821?

Spanish Texas, situated on the border of Spain’s vast North American empire, encompassed only a small portion of what is now the Lone Star State. Slightly more than three centuries elapsed between the time the Texas shoreline was first viewed by a Spaniard on an unknown date in 1519 and July 21, 1821, when the flag of Castile and León was lowered for the last time at San Antonio. Those 300 years saw an early era of exploration in which there was a preliminary evaluation of the land, its people, and its resources. As rumored wealthy Indian civilizations to the north of Mexico proved illusory, attention turned more to the south. Spain nevertheless determined to maintain her claim to present-day Texas, a defensive borderland with strategic significance based on geographical location.
