Kenedy County, among the last Texas counties formed, was not established until 1921, when Willacy, Cameron, and Hidalgo counties were reorganized. The stated reason for the county's formation was the considerable distance to the county seats of the other counties. But perhaps more important was the attempt of ranching interests to stave off the growing power of farmers who were beginning to develop the Rio Grande valley. The new county seat was established at Sarita, where John G. Kenedy, son of the founder of the King Ranch, had built his headquarters. -Handbook of Texas Online: Kenedy County
