The Louisiana tartan was officially recognized in 2001. Tartan refers to fabric woven into plaid patterns representing clans (families) or regions in Scotland.
In old Scotland, the tartan was used for clothing and as a banner or flag. Because a family or community worked the cloth together, their clothing was made of the same patterns, and so a person could be recognized by the Tartan plaid that he wore. Tartans can also be designed as a symbol commemorating a special event or person.
