What was feudalism?

At the top: Emperor (highest position, but no political power)

Second in line: Shogun (actual ruler, had political power)

Third in line: Daimyo (large landowners)

Fourth in line: Samurai/Ninja (warriors loyal to Daimyo)

The rest: Peasants (3/4 of population), Merchants (lowest status but gradually gained influence), Artisans (made sWords and armor for the Samurai class)

Compare it to medieval feudalism, very similar.
