being used to make scarlet dye in Spain, France, Italy, and Holland, and almost all the fine scarlet garments of Europe were made with cochineal. Scarlet was the traditional color of the British nobility in the 17th and 18th century. The members of the House of Lords wore red ceremonial gowns for the opening of Parliament, and today sit on red benches. The red military uniform was adopted by the British Army in 1645, and was still worn as a dress uniform until the outbreak of the First World War in August 1914.
