Iga Sokoku Ikki (伊賀惣国一揆, lit. Iga [Rural] Country Revolt) is a twelve-member council that governs Iga Province. It is also called the Iga Republic; In Seishin series, it is also called the Iga Alliance, Iga War Council, and Iga Administration. Most of the information below are what's depicted in Seishin.


Real Life

An union to oppose goverment or a large force, an ikki is an alliance formed for the purpose of military security against invaders, mainly from the feudal lords.[1] Sources state that Iga's ikki is the independent organization that does exactly that, with the Three Grand Iga Jonin playing a keyrole in leadership[2][3][4]. The ikki was destroyed during the Iga Tenshō Revolt (天正伊賀の乱, Tenshō Iga no Ran). Before the Onin War, Iga Province was under the charge of the Mikawa-affliated Niki family.[5], and before the Kamakura period, it was under the control of Tōdai-ji temple, the head provincial temple.

Ninja activity have peaked during the Warring States Period and the known history of ninja is mostly maintained in Seishin. Prior to Sengoku, defeated samurai fled to Iga Province to seek refuge in its mist-concealed mountain villages and developed different ninjutsu styles. Accounts of this can be led back to 12th century.

Apparently, there is a system where villagers are mobilized in emergency situations when a bell is rung[6][7]

In Seishin Series

Despite the definition of Ikki, the Iga Sokoku was founded by Iga Province's local warriors to create a useful network and maintain public peace. They formed a unique self-governing republic (see autonomous republic) of twelve key figures. The name of the government is an honorable title. The Sokoku's primary bases are at the Heirakuji (平楽寺) and Tendōzan (天童山) temples in Ueno. Iga as young at 17 and as old as 50 take to the field.

During wartime, the Ikki play a familiar role in fighting against oppressive forces and its leaders coordinate the people of Iga Province to maintain land security and obedience. The Ikki also takes charge in other activities such as intelligence gathering and training. It is a doctrine that ninjutsu is a form of strategy to protect the people of Iga; aside from battle, martial arts is also traditionally taught to achieve better physical and spiritual conditioning. Furthermore, the Ikki upholds the cessation of Iga and Koka's rivalries by forbidding violence between the shinobi. As a result, whenever there is a threat, Iga and Koga are to join forces as a "league of equal villages" to combat it.
