on a way to prepare to create the politics of the kingdoms and empires in my novel I want to begin. I want my novel to take place in a sort of 1700s-1800s timeline, what could I do to make these nations as accurate as possible. So for instance. One of the most powerful nations would be the Lionite Empire, something like the British Empire in our timeline, I plan to have it as a constitutional monarchy, like Britain with a Parliament with houses. I have taken the liberty to studying politics but I would like to ask how to make it the most accurate. I am still working on the names and some of the nations still haven't been given a name or political structure yet.
Name Of the Nations and their Politics
Lionite Empire Constitutional Monarchy
King with some power
Mislov Similar to Russia.
King with absolute power
Under the Tsar
Harpsburg Kingdom Similar to Hapsburg Austria
Lead by the Harpsburg Dynasty
Glorianas Reich Similar to Prussia
Jingoistic in nature
Jacobite Republic Revolutionary France.
Not to be confused with the real Jacobites.
Republican assembly with separate estates.
Post Revolution,still divided and torn
Lead by Consul Maurize Jacobite (Like Napoleon)
If this sounds too similar to Napoleonic Europe don't worry, the nations will be pitted against each other in different ways, I plan to do those later, but I wanted to use Napoleonic Europe as a base, so how does it look? Should I spend more time on the politics and structure them differently? Or are the nations here fine the way they are.
