RSP (Standing for Royal Sectored Platon, other names include Platon, Royal Sectori, Sectored Federation) has been around since the year 1AS. It's nation has thrived ever since as it went through thick and thin, still keeping the nationalist spirit.
The Federational Monarch Age is the oldest time of RPS, it's the time when a family took control of the nation, first elected by it's people. The Father divided his states between his spouse and children, making himself the head of government, as a pose to state. They assumed total control and became Absolute Monarchests.
