Guru Amar Das becomes the Third Sikh guru.

Guru Amar Das, sometimes spelled as Guru Amardas, was the third of the Ten Gurus of Sikhism and became Sikh Guru on 26 March 1552 at age 73.

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. Nine other human gurus succeeded him 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. The guruship was also passed onto the Guru Panth, consisting of the Khalsa; however, this form of guruship went into decline following to rise of Ranjit Singh.
