What were the warlord rulers of 300 small states in Japan following the civil war known as?

The warlord rulers of the fragmented and tumultuous period in Japan following the civil wars are referred to as daimyos. During the Sengoku period, which translates to "Warring States," many regional lords, or daimyos, gained significant power and control over their territories. Each daimyo operated much like an independent ruler, often with their own samurai armies, and engaged in continuous conflict with one another to expand their influence.

The term "shogun" refers to a military leader or general of Japan, particularly the one who held ultimate authority in the feudal system, but it does not specifically characterize the small-state rulers of this particular era. "Sengoku" is the name of the period itself rather than the rulers, so it is not applicable in this context. "Kabuki," on the other hand, is a form of classical Japanese dance-drama and has no direct relation to military leadership or governance. Thus, the identification of these warlords as daimyos accurately reflects their role during this critical historical timeframe in Japan.
