According to the Indian epic poem Mahābhārata, a dynastic succession struggle between two groups of cousins of an Indo-Aryan kingdom called Kuru, the Kauravas and Pandavas, for the throne of Hastinapura resulted in the Kurukshetra War in which a number of ancient kingdoms participated as allies of the rival groups. The location of the battle was Kurukshetra in the modern state of Haryana in India. The conflict is believed to form an essential component of an ancient work called Jaya and hence the epic Mahābhārata.

Mahābhārata states that the war lasted only eighteen days during which vast armies from all over the Indian Subcontinent fought alongside the two rivals. Despite only referring to these eighteen days, the war narrative forms more than a quarter of the book, suggesting its relative importance within the epic, which overall spans decades of the warring families.

The narrative describes individual battles of various heroes of both sides, battle-field deaths of some of the prominent heroes, military formations employed on each day by both armies, war diplomacy, meetings and discussions among the heroes and commanders before commencement of war on each day and the weapons used. The chapters (parvas) dealing with the war (from chapter six to ten) are considered amongst the oldest in the entire Mahābhārata.^{[citation needed]}

Kurukshetra  pronunciation (help·info) (Hindi: कुरुक्षेत्र) is a land of historical and religious importance. Historically the land belonged to Punjab, but now it is a district in Haryana state of India. It is a holy place and is also known as Dharmakshetra ("Holy City"). According to the Puranas, Kurukshetra is named after King Kuru, the ancestor of Kauravas and Pandavas, as depicted in epic Mahabharata. The importance of the place is attributed to the fact that the Kurukshetra War of the Mahabharata was fought on this land and the Bhagavad Gita was preached on this land during the war when Lord Krishna found Arjuna in a terrible dilemma.

Rashtrakavi Ramdhari Singh 'Dinkar' has written an epic poem by the title of Kurukshetra. It is a narrative poem based on the Santi Parva of the Mahabharata. It was written at a time when the memories of the Second World War were fresh on the mind of the poet.

Thanesar or Sthaneswar is a historical town located adjacent to what is now the newly created Kurukshetra city. Thanesar derives its name from the word "Sthaneshwar", which means "Place of God". The Sthaneshwar Mahadev Temple, whose presiding deity is Lord Shiva, is believed to be the oldest temple in the vicinity. Local hearsay identifies the legendary "Kurukshetra" with a nearby place known as Thanesar. A few kilometers from Kurukshetra is the village known as Amin, where there are remnants of a fort which is believed to be Abhimanyu's fort.
