The Sikh gurus are the spiritual masters of Sikhism, who established the religion over the course of about two and a half centuries, beginning in 1469. The year 1469 marks the birth of Guru Nanak, the founder of Sikhism. He was succeeded by nine other human gurus until, in 1708, the Guruship was finally passed on by the tenth guru to the holy Sikh scripture, Guru Granth Sahib, which is now considered the living Guru by the followers of the Sikh faith.
