Sikhism

The Sikh Gurus (Prophet-Masters) established Sikhism over the centuries, beginning in the year 1469. Guru Nanak was the first Guru, and subsequently, each Guru, in succession, was referred to as "Nanak", and as "Light", making their revelations, in the holy scriptures, equivalent. All the Gurus themselves also used the name "Nanak" while penning down their spiritual revelations.
There are a total of Eleven Gurus:

Ten human gurus and the Eleventh, or Current and Everlasting Sikh Guru, is the integrated Sikh scripture known as the Guru Granth Sahib. The Tenth Nanak, Guru Gobind Singh, had bestowed the Guruship forevermore to the Guru Granth Sahib.
