Atascosa County. As early as 1722 El Camino Real (The King's Highway) from the Rio Grande to San Antonio was well established in this area. The Spanish word "Atascosa," denoting boggy ground that hindered travel, gave region its name. The county was created in 1856 from land formerly in Bexar County. Jose Antonio Navarro, whose 1831 claim was the first grant recorded in area, gave land in 1857 for first county seat, Navatasco. County seat moved to Pleasanton in 1858, to Jourdanton in 1911. Livestock, oil, gas and strawberries are well-known products of the county. #223
