Jaichand was the name of the last ruler of Kannauj belonging to the Rathore dynasty.
Jaichand, ruled the north Indian kingdom of Kannauj during the reign of Prithvi Raj Chauhan. He had enmity with the ruler of Delhi and this grew further when his daughter Samyogita married Chauhan against his wish. Even after multiple defeats, when Muhammad Ghori successfully launched attack on the forces of Delhi, Prithvi Raj requested Jaichand to fight the invader together. To this Jaichand not only bluntly refused, he went to the Ghori camp to fight against Chauhan. After the defeat of Prithvi Raj Chauhan in the Second Battle of Tarain in 1192, Muhammad Ghori then turned his guns on Jaichand. Battle of Chandvar, 1194 ensued in which Jaichand was defeated. Jaichand died when he was trying to flee, while crossing the Ganges, and his descendents managed to escape to the region of Marusthali, where they established the Rathore kingdom of Marwar a few centuries late. Today, Jaichand is considered among the greatest traitors who made way smooth for the islamic invasion of India.
