Kadsreius Sentanese Republic was a partially-recognized territory of the Sentanese Empire established in 1940 by exiled Sentanese general Hiroshi Kayos with newly-built Eirabourne as its capital. KSR was never recognized and claimed to be the part of the Sentanese Empire. KSR later invaded most of the Sentanese Empire's land and some of Vicnoran Kingdom's land in 1950 during the Eight-Day War, which will later become the Republic of El Kadsre.
