Guru Angad Dev Ji (31 March 1504 – 29 March 1552) was the second of the ten Sikh Gurus. He was born in a Hindu family, with the birth name Lehna, in the village of Harike (now Sarae Naga, near Muktsar) in the northwest Indian subcontinent. Bhai Lehna grew up in a Khatri family (Kshatriya, traditionally warriors), his father was a small-scale trader, and he worked as a pujari (priest) and religious teacher centered around the goddess Durga. He met Guru Nanak, the founder of Sikhism, and became a Sikh. He served and worked with Guru Nanak for many years. Guru Nanak gave Bhai Lehna the name Angad, chose Angad as the second Sikh Guru instead of his own sons. After the death of Guru Nanak in 1539, Guru Angad led the Sikh tradition. He is remembered in Sikhism for adopting and formalizing the Gurmukhi alphabet from pre-existing Indo-European scripts such as the Tankre of the Himalayan region. He began the process of collecting the hymns of Nanak and contributed 62 or 63 hymns of his own. Instead of his son, he chose a Vaishnava Hindu Amar Das as his successor and the third Guru of Sikhism.

Guru Angad Dev Ji was born in a village, with the birth name of Lehna, to Hindu parents living in the northwestern part of the Indian subcontinent called the Punjab region. He was the son of a small but successful trader named Pheru Mal. His mother's name was Mata Ramo (also known as Mata Sabhirai, Mansa Devi, and Daya Kaur). Like all the Sikh Gurus, Lehna came from the Khatri caste. At age 16, Angad married a Khatri girl named Mata Khivi in January 1520. They had two sons (Dasu and Datu) and one or two daughters (Amro and Anokhi), depending on the primary sources. The entire family of his father had left their ancestral village in fear of the invasion of Babar's armies. After this, the family settled at Khadur Sahib, a village near the River Beas that is now Tarn Taran. Before becoming a Sikh and his renaming as Angad, Lehna was a religious teacher and priest who performed services focused on Durga (Devi Shaktism, the goddess tradition of Hinduism). Bhai Lehna in his late 20s sought out Guru Nanak, became his disciple, and displayed deep and loyal service to his Guru for about six to seven years in Kartarpur.
