The Sheriffs' Association of Texas is one of the oldest law enforcement associations in the nation. The Sheriffs' Association of Texas met for the first time on August 14, 1874, in the courthouse in Corsicana, Navarro County, Texas. The meeting was called to order by Sul Ross, Sheriff of McLennan County, who later became a notable part of Texas history.
The Sheriffs began annual training conferences in 1878. These training conferences today are the largest composite gathering of law enforcement officers in Texas. Sheriffs and other county and local law enforcement officers, federal and state officers, and major industry security personnel attend.
