Gugu hat (罟罟冠 or 固姑冠 or 顧姑冠 or 故姑冠; pronounced as Guguguan in Chinese) is a tall headdress worn by Mongol noblewomen before and during the Yuan dynasty.[1][2] It is also known as boqta,boghta,botta, boghtagh or boqtaq.[1][3][4] The gugu hat was one of the hallmark headdress of Mongol women in the 13th and 14th century.[1] It was always worn with the formal robe of Mongol women.[1]
The boqta also appeared in the Ilkhanate (1256–1335 AD),[5] in Korea when Mongol princesses married in the Goryeo court,[6] and continued to be used in the Timurid court in the 15th century AD.[7]
