Why Did Japanese clans fight each other?

Japanese clans fought each other primarily due to power struggles, territorial disputes, and the pursuit of influence during periods of political instability, such as the Heian and Sengoku eras. These conflicts often stemmed from feudal loyalties and the desire to control resources, land, and trade routes. Clans sought to establish dominance over rival factions to secure their survival and elevate their status within the complex hierarchy of Japanese society. Additionally, cultural and personal rivalries played a significant role in fueling these clan confrontations.
