Guru Angad dev ji was the second of the ten Sikh Gurus. He was born in the village of Sarae Naga in Mukatsar district in Punjab, on March 31, 1504 and given the name Lehna shortly after his birth as was the custom of his Hindu parents. He was the son of a small successful trader named Pheru. His mother's name was Mata Ramo (also known as Mata Sabhirai, Mansa Devi and Daya kaur). Baba Narayan Das Trehan was his grandfather, whose ancestral house was at Matte-di-Sarai near Mukatsar.
In 1538, Guru Nanak Ji chose Lehna, his disciple, as a successor to the Guruship rather than one of his sons.Bhai Lehna was given the name Angad and designated Guru Angad, becoming the second guru of the Sikhs. He continued the work started by the first Sikh Guru, Guru Nanak Ji.
He married Mata Khivi in January 1520 and had two sons (Dasu and Datu) and two daughters (Amro and Anokhi). The whole 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 shaib, a village by the River Beas, near what is now Tarn Taran a small town about 25 km from the city of Amritsar the Holiest site of the Sikhs.
Guru Angad dev ji invented the present form of the Gurmukhi script. It became the medium of writing the Punjabi language in which the hymns of the Gurus are expressed This step had a far-reaching purpose and impact. First, it gave the people who spoke this language an identity of their own, enabling them to express their thought directly and without any difficulty or transliteration. The measure had the effect of establishing the independence of the mission and the followers of the Guru. Secondly, it helped the community to dissociate itself from the Sanskrit religous tradition so that the growth and development of the Sikhs could take place unhampered and unprejudiced by the backlog of the earlier religious and social philosophies and practices. This measure, as shown by the subsequent growth of Sikhism, was essential in order to secure its unhindered development and progress as it required an entirely different approach to life.
