Since last time my thread was apparently too high-concept for people to ignore the Tripartite Alliance Earth timeline aspect of the idea to focus on the idea itself, I'll just quote sparingly.
Long story short how can we have a more distinctly Francophone and French cultural Louisiana? This is a good "laboratory" of sorts to study the possibility of an American state of Quebec.
...Under the terms of the purchase, the large Francophone community of Louisiana was to retain the full of the French language in government and education. The conclusion of the Anglo-American War in 1815 brought an end to British attempts at conquest, and Louisiana was confirmed as an American state.
Louisiana's population was quite diverse, but it was still Francophone. The Cadiens -- survivors of the British deportation of the Acadiens from eastern Canada in the Seven Years War -- constituted the single largest group of Louisiana Francophones, rapidly expanding in number throughout the bayous and prairies of western Louisiana. In the east of Louisiana, the Creoles descended from the pre-Seven Years War settlers vied with the tens of thousands of settlers Napoleonophile settlers who fled France after 1814 for control of state politics. There was also a large group of Black Creoles, descended from Caribbean immigrants and slaves. By the eve of the First Civil War, these Francophone groups constituted almost three-quarters of the Louisianan population. In addition to the Francophones, there was a large Anglo-American community took shape in New Orleans to profit from the Mississippi trade, and forty-five thousand immigrants -- nearly all Catholic, mainly French, Irish, Spanish, or Italian, most settlers in the New Orleans area.
Even though Louisiana was a Southern state, the passage of the Graduated Emancipation Law in 1853 also made it a free state. The rapid growth of the Cadien, Creole, and foreign Catholic agricultural settlements led to the formation of a free agricultural peasantry, unique in the South. This, and the ideological opposition to slavery on the part of the Catholic Church, led to Louisiana opting to remain outside the secessionist Confederacy, and to remain loyal to the Union, consequently making Louisiana the first target of the Confederacy...
