The province of Batman has a population of around 600,000 people and is an important area for oil production.
It is pronounced "Baht-man" - named after an old Turkish measure of weight.
In 2008, the mayor of the city of Batman said he wanted to sue Warner Bros for using the name of the province in the film Batman Begins and The Dark Knight without paying royalties.
But a lawsuit never materialised as it appears that the character of Batman was created in the 1930s, 20 years before the creation of the province.
