Mount & Blade: Warband Mod - Gekokujo v2.1a

The name is a term often translated as "the low-ranked taking over from the high" and was chosen because it was a running theme during that era: from the illustrious Ouchi clan--a belligerent party in the Onin war--being displaced by the Mori (their vassals); to the rise of Toyotomi Hideyoshi (who began his career as a cook and sandal bearer); to the beginning of the Tokugawa shogunate itself (Ieyasu was an upstart who probably fabricated a claim of descent from the Minamoto clan--the only ones allowed to be granted the title of Shogun in the first place). As a player of Gekokujo, you will start from nothing and attempt to gain control of the entire country, making the title even more fitting.
Gekokujo is a mod for Mount and Blade Warband set in the Sengoku period of Japan.
