The Mahabharata is the history of the Great War of India between the Pandavas and the Kauravas. The two brothers Dhritarashtra and Pandu were born through sage Vyasa after the death of Vichitravirya. Dhritarashtra being blind, Pandu succeeded to the throne but he entrusted the kingdom to his elder brother and himself proceeded to forest where his five sons Yudhishthira, etc., were born and were called the "Pandavas." Dhritarashtra also had one hundred children in Duryodhana and others, who were called the "Kauravas." Pandu died during the infancy of his sons and Dhritarashtra continued to rule the kingdom with the help of their granduncle Bhishma, who had pledged himself to lifelong celibacy. The Pandava and Kaurava princes were brought up together and also educated and trained alike through Dronacharya. Both sets of princes considered themselves entitled to the kingdom and looked upon the other with hostility and their feelings and relations grew strained from day to day. On account of persecution by the Kauravas, the Pandavas left their home and suffered much hardship and pain, but on their marriage with the daughter of Drupada, king Dhritarashtra sent for the Pandavas and made over half the kingdom to them. The Pandavas improved their country and established their capital at Indraprastha and then performed the horse-sacrifice with great pomp. The Kauravas were also invited there but on seeing the good fortune of the Pandavas and being offended by jokes made at them, they were overcome with jealousy and resentment and returned home with feelings of enmity and revenge. They then conspired against the Pandavas and invited them to gamble and thereby they won all their wealth, kingdom and their person and also insulted and ill-treated their wife, Draupadi, in the presence of all. In the end, it was settled that the Pandavas should go out in exile to the forest for twelve years and pass another year in secrecy and on return from the exile be entitled to get back their lost kingdom. The Pandavas did all this but on their return the Kauravas refused to return the kingdom. This gave rise to the great family war in which all the Kauravas and the two armies were annihilated and the Pandavas alone survived and got the victory. The Pandavas were assisted by Sri Krishna and other relations, Drupada, Virata, etc., and their forces numbered seven battalions (Akshauhinis). The Kauravas were also assisted by their relations and friends and their forces numbered eleven battalions. The Pandavas were successful on account of their righteous cause and divine grace.
