A cardigan was originally a long-sleeved military jacket of knitted worsted, trimmed with fur or braid and buttoned down the front. They were worn by British Army officers during the Crimean War, and were named after James Brudenell, the 7th Earl of Cardigan, who led the Charge of The Light Brigade. During the 20th century the style was adapted for sportswear, losing the collar, and became a popular item for home knitters. Research Cardigan
