The history of the kilt stretches back to at least late 16th century Scotland. However, the nationalism of that tradition is relatively recent. It was only with the Romantic Revival of the early 19th century that the highland kilt was adopted by Lowlanders and the Scottish Diaspora as a symbol of national identity. People from other countries with Celtic connections, some Irish, Cornish, Welsh and Manx, have also adopted tartan kilts in recent times, although to a lesser degree.
The kilt first appeared as the great kilt, a full length garment whose upper half could be worn as a cloak draped over the shoulder, or brought up over head as a cloak. The small kilt or walking kilt (similar to the 'modern' kilt) did not develop until the late 17th or early 18th century, and is essentially the bottom half of the great kilt.
