Pointy hats have been a distinctive item of headgear of a wide range of cultures throughout history, in particular suggesting an ancient Indo-European tradition, but they were also traditionally worn by women of Lapland, the Japanese, the Mi'kmaq people of Atlantic Canada, and the Huastecs of Veracruz and Aztec (illustrated e.g. in Codex Mendoza). The Kabiri of New Guinea have the diba, a pointy headgear glued together.
