Sikhism ( /ˈsiːkɨzəm/ or /ˈsɪkɨzəm/; Punjabi: ਸਿੱਖੀ, sikkhī, IPA: [ˈsɪkːʰiː]) is a monotheistic religion founded during the 15th century in the Punjab region, by Guru Nanak Dev and continued to progress with ten successive Sikh gurus (the last teaching being the holy scripture Gurū Granth Sāhib Ji). It is the fifth-largest organized religion in the world, with over 30 million Sikhs and one of the most steadily growing. This system of religious philosophy and expression has been traditionally known as the Gurmat (literally 'of the gurus'). Punjab of India is the only region in the world with a majority Sikh population.

Sikhs are expected to embody the qualities of a "Sant-Sipahie"—a saint-soldier. One must have control over one's internal vices and be able to be constantly immersed in virtues clarified in the Guru Granth Sahib. A Sikh must also have the courage to defend the rights of all who are wrongfully oppressed or persecuted irrespective of religion, colour, caste or creed.

The principal beliefs of Sikhi are faith and justice, in Waheguru—represented by the phrase ik ōaṅkār, meaning one God. Sikhi advocates the pursuit of salvation through personal meditation on the name and message of God. The followers of Sikhi are ordained to follow the teachings of the ten Sikh gurus, or enlightened leaders, as well as the holy scripture entitled the Gurū Granth Sāhib Ji, which, along with the writings of six of the ten Sikh Gurus, includes selected works of many devotees from diverse socio-economic and religious backgrounds. The text was decreed by Guru Gobind Singh Ji, the tenth guru, as the final guru of the Sikh religion. Sikhi's traditions and teachings are associated with the history, society and culture of Punjab. Adherents of Sikhi are known as Sikhs (students or disciples) and number over 26 million across the world.
