Duchy of Oneida

The Duchy of Oneida is an interstellar polity whose subject worlds are located in subsector F of Riphaeus sector. The Duchy was formed shortly after the formal establishment of the monarchy within the Empire of Nagoya, when the naval forces of Emperor Paulo II Yusha came to the aid of Admiral Cornelius Nevalton against privateers sponsored by the Domain of Tham to spinward. In recognition of this assistance, Admiral Nevalton swore fealty to Emperor Paulo and was granted the hereditary title of Koshaku (or Duke), which the Nevalton line has held ever since.

Though a close ally of the Empire of Nagoya, the Duchy of Oneida maintains a high degree of independence.
