Constables are among the earliest recorded peace officers in world history. From a very humble beginning in the 5th century, by the turn of the 6th century they were chief household officers. In France, Constables commanded the armies in the Kings absence. Becoming noted peacekeepers under King William 'The Conqueror' in 1066 Constable's responsibilities were expanded with the adoption of the Magna Carta, which not only became the pattern for most of the world's Constitutions, but also mentioned Constables in written law. Constables have served the Justice Court system since 1362.
In 1836, the Constitution of THE REPUBLIC OF TEXAS established Constables as the primary Law Enforcement Administrators, whose stature is still upheld under article 2.12 of the Code of Criminal Procedure. They are elected to four-year terms of office and are commissioned by the Governor of Texas as Law Enforcement Agencies just as the Sheriff's Department or Texas Department of Public Safety. In fact, a Constable is an associate member of the D.P.S. under section 411.009(a) of the Government Code. His/her "original" jurisdiction is anywhere in the county of election and is statewide in all criminal and most civil matters. To meet the challenges and demands of this responsibility Texas Constables MUST be licensed by Texas Commission On Law Enforcement.
