A scarf (: scarves or scarfs) is a long piece of fabric that is worn on or around the neck, shoulders, or head. A scarf is used for warmth, sun protection, cleanliness, fashion, religious reasons, or to show support for a sports club or team. Scarves can be made from materials including wool, linen, silk, and cotton. It is a common type of neckwear and a perennial accessory. Scarves have been worn since ancient times. In 1350 BC, in Ancient Egypt, Queen Nefertiti is said to have worn a tightly woven headscarf, and a 9th-century BC statue of Ashurnasirpal II depicts the emperor wearing a shawl. In 500 BC in Athens, women wore scarves to enhance their seductive charm; in the same period, Indian women wore them flirtatiously as headgear. During the reign of the Chinese Emperor Cheng, from 259 to 210 BC, scarves were used as military markers to identify the rank of Chinese warriors or their status as officers; many of the Terracotta Warriors are depicted wearing them. In Ancient Rome, around AD 10, the garment was used for cleanliness rather than warmth. It was called a focale or sudarium () and was used to wipe sweat from the neck and face in hot weather. Scarves were originally worn by men around their necks or were tied to belts. In the 1200s, Egyptian belly dancers wore a scarf-like belt low on the hips to highlight their body movements. Around the 17th century in Croatia, soldiers of all ranks wore scarves; officers wore silk scarves while other ranks were issued with cotton scarves. Some Croatian soldiers served as mercenaries with the French forces; their scarves were sometimes referred to as "cravats" (from the French cravate, meaning "Croat"), and were the precursor to the necktie. The modern British "cravat" is called an "ascot" in American English. During the French Revolution, women and men wore differently coloured scarves to display their political affiliations to democratic principles of Liberté, Egalité, Fraternité; and Cravates. The French epitomised the elegant scarf style.
