Louise Grimaldi had been crowned Princess of Monaco, but there was no law that said what that meant. As a matter of fact, Monaco was operating without much in the way of established law as the citizens simply came together to discuss their day to day affairs. It was not without conflict, but it was at least democratic.

Louise gathered the eldest members of the Monégasque families after asking each of them to collect the needs and wishes of their family members. Consulting old tomes on law and all locals who were in some way educated in law - mostly by the Romano-Imperial State, Louise found the most capable people to help them in the process of drafting the constitution. Lastly, she invited the Archbishop of Monaco, Tristan Landi. He, on his turn, invited the Princess to the Saint Nicholas Cathedral to begin the work. The cathedral was in a poor shape, having served a dozen different functions since the nuclear exchange from hospital to armoury, but it still stood and symbolically its value was immense.

After months of work, the Constitution of September 11 2046 was submitted to the public of Monaco. Important excerpts include:
