The term is used in the Mahabharata with two meanings;
1. the wider meaning, to represent all the descendants of Kuru. This meaning, which includes the Pandava brothers, is also sometimes used in the Mahabharata, especially in some of the earlier parts.
2. the commoner and narrower meaning, to represent the elder line of the descendants of King Kuru. This restricts it to the children of King Dhritarashtra, as his line is the elder line of descent from Kuru. It excludes the children of the younger brother Pandu, who founds his own line, the Pandava. The rest of this article deals with the children of Dhritarashtra, by Queen Gandhari.

She became pregnant, but did not deliver for two years, after which she gave birth to a lump of flesh. Vyasa cut this lump into a hunderd and pieces, and these eventually developed into a hundred boys and one girl.

Although all hundred sons have been named, only the first few are normally mentioned in the Mahabharata. The first five are;
All the male Kauravas were killed in the great battle at Kurukshetra.
