The Great Sekowan War was a massive conflict between the Commonwealth of Nations Aliance and the ultra-nationlist government of Tenno Kumiko in the nation of Sekowo. This war was noted to be the first major military operation that has involved all Rothingren monarchs in the Commonwealth Alliance. Fighting lasted until the year 2980 when Empress Kumiko Yukio abdicated the throne of the Empire Magnificent and fled into hiding; the Second Sekowan Empire was disestablished and the Ishida Dyansty returned to power under Emperor Kenji.
