1886 was an eventful year for the British. Decades of alliances, pacts and wars culminated in a grand coordinated rebellion against British colonialism. The British were only able to evacuate the most important governors and aristocrats, while the Army was overrun. Seeing it pointless to try and reestablish rule, Britain seceded rule of the island to the Cestlep-based headquarters of the rebellion: the Oceanykan Council. With this was born the Oceanykan Federation, commonly known as the "Old Republic". The parliament-like organisation, featuring representation by the major groups of the nation, had de jure rule over the country. Despite an extremely weak constitution the Federation managed to coordinate several of its members to participate in development projects. This early era of the Old Republic is commonly known as the Oceanykan Golden Era. The country adopted many modern technologies such as industrial production, railroads and machineguns. Wars were plentiful but not nearly as much as before. The Council even sent its army to fight in the Weltkrieg, with mixed results. But a particular era of strife directly following the end of hostilities corrupted and weakened the Council. By the time all radical rebellions of the second Weltkrieg were exterminated, the Council was not the group of idealistic statesmen and industrialists it was before.

The greatest crisis that Oceanyka's new republican government faced was the Oceanykan Civil War, in which it found itself victorious. However, the country remained in a state of political, social and economic decay, and thus the end of said civil conflict marks the beginning of the Late Republican Age.
