A capotain, capatain or copotain is a tall-crowned, narrow-brimmed, slightly conical "sugarloaf" hat, usually black, worn by men and women from the 1590s into the mid-seventeenth century in England and northwestern Europe. Earlier capotains had rounded crowns; later, the crown was flat at the top.
The capotain is especially associated with Puritan costume in England in the years leading up to the English Civil War and during the years of the Commonwealth. It is also commonly called a flat topped hat and a Pilgrim hat, the latter for its association with the Pilgrims who settled Plymouth Colony in the 1620s. Contrary to popular myth, capotains never included buckles on the front of them; this image was created in the 19th century.
It has been theorised that the capotain inspired the top hat.
