How much power did Napoleonic's Sister Republica have?
I know that Napoleon had near absolute power in Europe by crowning himself Emperor and marching into Russia & Egypt,subdued the Austrians as a bonus. In terms of his sister republics though how much power was allowed to them which would have elevated them above mere client status.
Where these states effectively vassals of the French Emperor or are we talking about actual powers being transferred to them? Sovereign states that could operate with a degree of independence.
