Several times I got to hear that Mahabharata battle fought in Kurukshetra is also famously known as Dharma-Yuddha.
This battle was fought between Pandavas and Kauravas who were cousins then why it is still called as Dharma-yuddha?
Mythology is followed by most of the people irrespective of science facts. All it teaches is to be a better human. In the same aspect Mahabharata was explained in such a way that Dharma will be apex of any other aspect in the universe. When a man stands for Dharma, all his relations fall under it and no matter what consequences he may face, all you need is to fight for Dharma.
Mahabharatha was explained to Arjuna by Lord Krishna in the battle field, which include many slokas that helped Arjuna in the later stages of war.
Many assumptions are made to get the facts about the existence of epics like Mahabharatha, Ramayana as well.
It is a story of every man who was tightly coupled with lot of emotions and in the end still stands for Dharma. Thus Mahabharatha became sacred epic for every human who observe the intense of morals stuffed in it.
Any reviews to my answer are happily accepted, and corrections appreciated. Thank You.
It is called Dharma-yuddha because the Mahābhārata, in its opening chapter, divides the major characters into two different groups, one based on dharma and the other on adharma. The rest of the story, including events that lead up to the Kurukṣetra war, follows this theme.

Duryodhana is a great tree created out of passion, Karna is its trunk, Shakuni is its branches, Duhshashana is the plentiful fruit and flowers and the mindless Dhritarashtra is its root.

Yudhishthira is a great tree created out of righteousness, Arjuna is its trunk, Bhima is its branches, the two sons of Madri are its plentiful fruit and flowers, and Krishna, Brahma and the Brahmanas are the root
