Gobind Singh was the only son of Guru Tegh Bahadur, the ninth Sikh guru, and Mata Gujri. He was born in Patna, Bihar on 22 December 1666 while his father was visiting Bengal and Assam. His birth name was Gobind Das/Rai, and a shrine named Takht Sri Patna Harimandar Sahib marks the site of the house where he was born and spent the first four years of his life. In 1670, his family returned to Punjab, and in March 1672 they moved to Chakk Nanaki in the Himalayan foothills of north India, called the Sivalik range, where he was schooled.
