The Miyoshi clan was a prominent samurai family in Japan during the late Muromachi period (1336-1573). They were known for their military prowess and played a significant role in the political landscape of the time, often serving as vassals to powerful daimyōs. The clan's influence extended across the Shikoku region, where they established their power and engaged in various conflicts. The clan's most notable figure was Miyoshi Nagayoshi, who became a key player in the struggle for power during the Sengoku period (1467-1603). The clan eventually declined in influence due to internal strife and the rise of other powerful families, leading to their eventual dissolution.
