During the 17th Century bands of hatamoto, samurai vassals of the Tokugawa shogunate, were causing havoc in the new capital city of Edo. Opposing them was Banzui-in Chobei,whose sole aim was to save Edo from the hatamoto as their violent behavior threatened to pull apart the very fabric of society.
A Conspiracy Theory explains an event as being the result of an alleged plot by a covert group or organization or, more broadly, the idea that important political, social or economic events are the products of secret plots that are largely unknown to the general public. The term "conspiracy theory" is used to indicate a narrative genre that includes a broad selection of (not necessarily related) arguments for the existence of grand conspiracies. The term is frequently used by scholars and in popular culture to identify secret military, banking, or political actions. Conspiracy theories are based on the notion that complex plots are put into motion by powerful hidden forces.
