Majitha is situated 16 kilometre to the north east of Amritsar. The town is connected with Amritsar by train and road. The town was founded by one Madho, a Jat of the Gill clan. He was 'jetha' (the eldest son) of his father and hence the place was 'Madho-Jetha'. The 'Madho-Jetha' subsequently got contracted into Majitha. Madho was thus the ancestor of Majithia Sardars, some of whom held high positions during the Sikh rule. It is believed that the forefathers of legendary Maharaja Ranjit Singh were closely associated with the town.
