Clans

A Clan (一族, Ichizoku; Literally meaning "family"), is a group of different units joined together to form an alliance which make up their Clan. These Clans have some Unique Abilities and Shared Races of units in them. This unique abilities of units found in most of the Clans sometimes make up their main theme to represent themselves with their Unique traits. The Senju clan and Uchiha clan were the first known clans to have agreed to settle and form a shinobi village, facilitated by creating agreements with the daimyō of the land they inhabit.

Membership in a clan is usually determined by blood relations and genetics, which is vital in the usage of kekkei genkai and secret techniques. These attributes and abilities made many clans feared and renowned throughout many villages. While clans may be composed of many individuals and extended families, many clans mentioned and seen in the series were somewhat limited to a nuclear family.
