How can one recognize french military uniform in 18th century?
Due to the turbulent events of the French Revolution, the uniforms of the French army changed numerous times during the 18th century. Before the revolution, French infantry usually wore white which was changed to blue after the Revolution. Cavalry units wore a large number of different colors, mainly green, red, and blue, which was usually dictated by their individual regiment. Foreign units, such as the Irish and Swiss regiments, often wore red uniforms, but these again could often change. In all, there is no one definitive uniform for 18th century France, but pre-revolutionary uniforms will mostly like be white and post-revolutionary ones will most likely be blue.
