<human>:  Why did the Indian emperor Ranjit Singh have a turban?
<bot>: The turban was a symbol of his status as a Sikh. The Sikhs were a religious community that was founded by Guru Nanak Dev in the 1500s. They were known for their belief in equality and their use of the turban. The Sikhs believe that a person should be judged by his character and not by his appearance.
