The origins of Sikhism are traced back to 1469 in the Punjab region, marking the birth of Guru Nanak. As the founder of this distinct religious tradition, Guru Nanak introduced a spiritual path that emphasised devotion to a single, formless God and the importance of leading an ethical life. His teachings challenged the prevailing social and religious structures of the time, advocating for equality and compassion across all communities.

Central to the development of the faith were the core principles established by Guru Nanak, which continue to define the Sikh way of life. These tenets focus on the integration of spiritual devotion with active service to humanity, rejecting asceticism in favour of living as a householder who remains mindful of the divine. The following pillars reflect the foundational values introduced during this period:

• Devotion to the one creator, known as Ik Onkar.
• The pursuit of honest labour and truthful living.
• The practice of selfless service, or Seva, to the community.
• The rejection of caste-based discrimination and social hierarchy.
• The promotion of equality between all individuals regardless of gender or background.

By establishing these doctrines, Guru Nanak laid the groundwork for a movement that would grow into a major world religion. His message encouraged followers to seek direct communion with the divine through meditation and the remembrance of God's name, rather than through complex rituals or priestly mediation. This emphasis on simplicity and sincerity helped Sikhism gain a firm footing in the cultural and religious landscape of northern India, eventually evolving into the organised faith recognised today.
