Serene Republic of Côrsiggé

The Serene Republic of Côrsiggé was a Western Oenotrien parliamentary republic with elective monarchistic features that replaced the Grand Duchy of Côrsiggé in 1679. The mixed government model that combined a monarchy in the Dojé and a legislative republic in the Great Council was established by Eutàlié Sannse, a Côrsiggéan military and political leader, following the Civil War. The Republic's distinctive features were heavily influenced by the writings of Côrsiggéan philosopher Igène Martìne, who considered the republic a success:"“If it is my work Sannse intends to adhere to in ‘is Dojéship, he must have a copy ready at hand. To my Eye, Sannse not only reads my Volumes nightly, as one’d read letters from a Dear Lover, but he Remembers my Words as if they were the Words of Édiôniesù Himself.”"Despite the Republic’s adherence to Martìne’s political treatises, Central Côrsiggéans still sympathized with the former monarchs of House of Pèllicerre. Eventually, the Republic lost its territories there. Chaumentaine trading outposts located in the Gál Thálasse favoured the Republic for its laissez-faire economic policies, which allowed it to sustain itself. Eutàlié Sannse, promising low shipment fees and offering Côrsiggéan interest in their goods, convinced the trading outposts to become dependencies of the Republic.

Chaumentaine Minister-Regent Pôncellé Rèverredín declared war in 1680. Without the support of the Central Côrsiggéans, the Republic was unable to defend itself from Chaumentaine naval invasions. The brief war between Chaumentaine and the Republic resulted in the restoration of the Grand Duchy and the Pèllicerre monarchy under Ceperano Pèllicerre, a cousin of Sabiná Pèllicerre.
