The Kuroda clan was a prominent samurai family in Japan during the feudal era, particularly known for their influence in the Kyushu region. They played a significant role in the Sengoku period, a time of social upheaval and military conflict, and were known for their strategic alliances and military prowess. The clan's most notable figure was Kuroda Nagamasa, who served under the powerful warlord Toyotomi Hideyoshi. After the unification of Japan, the Kuroda clan was granted the Fukuoka Domain, where they continued to wield power and influence in the Edo period, contributing to the political landscape of Japan.
