<human>:  What was the cause of the war in the Kurukshetra War?
<bot>: The war was fought between the Pandavas and the Kauravas, who were cousins. The war was fought because the Pandavas had been exiled by their uncle, the king of Hastinapur, for killing his brother in a dispute over a kingdom. The Kauravas wanted to get revenge for the murder of their father. The Kauravas won the war, but were then exiled themselves by the Pandavas.
