However, by early 1793, having guillotined Louis XVI of France on 21 January, France found itself at war with a coalition including Great Britain, the German States, the Kingdom of Piedmont-Sardinia, and Spain in addition to Austria and Prussia.
The Army included three main types of infantry, all with different uniforms, organizations, equipment, and rates of pay: The variations between units created logistical problems, and animosity (due to different rates of pay) among units.
The purpose of the Demi-brigade was to blend all three formations into a single unit, with identical equipment, organization, pay, and uniforms.
The levée en masse had swelled the ranks of the French army, so by August 1794 over a million men (1,075,000) were under arms.
As the French Revolutionary Wars progressed, demi-brigades were issued with specific coloured uniform jackets.
Peace was restored under the Treaty of Amiens in 1802, and Napoleon ordered the reinstatement of the historic term "régiment" in 1803.
