Those Anglo states must be an incredible thorn in the side of that mega New France
They used to be, not really anymore, the idea I have is that there was a divide between the anglo states because of Britain always favoring the bigger states in border treaties and the like, leading to the smaller states to feel betrayed by the UK, and they turn to Louisiana, who has been the dominant power in their continent for decades now, for help, Louisiana agrees to help the smaller states in a secret treaty that dosen't start until Britain is distracted in some huge war so they can't bother to defend their coastal colonies, when it finally does happen Louisiana and their allies (South Carolina, Maryland, Delaware, New Jersey, Connecticut, Rhode Island, New Hampshire, and Mainer rebels) all declare war on the remaining states, when the war is won for Louisiana they force friendly governments into all other states and allow their allies to take any land they want. this leads to a bitter hatred from Britain toward Louisiana, but they're too devastated from the war to really do anything about it.
