What is the leader of Sikhism called?

Answer 1

Sikhs don't have any religious leader nor do they have any priestly class for performing religious functions.At their place of worship which is Gurudwara, there is usually a person who act as more of a care taker than being a religious leader. That person is usually called Granthi or Bhaji. Sikhs do have what they call Akal Takhat where they do make religious decision. The head of Akal Takhat is called Jethadar. But its more of an organisation where people make decision after discussion and sometimes even arguments. But as such there is no religious leader.
