King's Infantry Regiment (France)

Régiment du Roi (King's Regiment) was a name given to several of the most prestigious regiments of the French Army under the ancien Régime and Bourbon Restoration, with most of the Army's branches having a régiment du Roi.

It is not to be confused with the term régiment royal (meaning a regiment belonging to the king as opposed to régiments de gentilhomme belonging to nobles) In 1663, the régiment Royal Infanterie was renamed the King's Infantry Regiment.

This regiment was one of three garrisoning Nancy in August 1790 and as such played a leading role in the mutiny known as the Nancy affair.

In 1814 the 1st Infantry Regiment was renamed régiment du Roi; it lost that name in 1816 when a new system of "Departmental Legions" replaced the former regiments of the French line infantry.

Five cavalry regiments were also redesignated as King's regiments in 1814 as part of a general effort under the First Restoration to dilute Napoleonic links within the French Army.
