A House Divided, Standing: North America, 1844-95

Decided to continue my earlier brief pixel work, A House Divided, Standing, with an outline of North American history from the conclusion of the original to 1895, going through the establishment of the American Confederation. The basic idea of North American history ITTL is that, despite the lack of American western expansion, there are still significant numbers of American citizens going west and settling western lands, and still large numbers of immigration to North America--in fact, even more than OTL due to various events and wars in Europe.

These factors lead to Texas and California being established by Anglo-American settlers with strong pan-American ideologies. Louisiana is divided between the nascent Texas Republic--established during the Mexican War of Independence by American filibusters but unable to join the U.S. due to British threats--and British North America early on thanks to nobody feeling secure with British control over the mouth of the Mississippi and de facto Texas control of much of Louisiana (thanks mostly to the aforementioned American settlers).

A California chock-full of English-speaking immigrants thanks to an earlier Gold Rush gains its independence from a Mexico torn apart by civil war in the 1840s.  Large numbers of Anglo-American settlers agitate for home rule in British North America, making up majorities of much of the colony, particularly in Oregon and the Great Lakes region, and are granted it by a British government fearful of the consequences of refusing. However, during the British Revolution, the various regions of BNA recognize that they cannot survive on their own and thus federate, reluctantly, into Rupertia, which shortly purchases Alaska.

Seemingly irreconcilable regionalist and pan-American sentiments prevail across the continent by the year 1870, and a compromise is reached between the two in the form of the North American Associative Treaty, which sets up a timeline for unification under a single government in 10 years' time, and a "trial period" for constitutional reform purposes through 1885. By the time the final constitution of the American Confederation is written, both the pan-Americans and regionalists get what they want with the creation of the Nine Republics, autonomous bodies subordinate to the President, Senate, and Assembly of the Confederation. 

Five members of the technically nonpartisan Senate are appointed by each Republic's government, and while the office of President is also technically non-partisan and only eligible for a single term, candidates may receive "endorsements" from various parties and alliances, leading to informal, shifting coalitions dominating Confederation politics. Thus, the best way to discover party strength in the Confederation is in the lower house, the Confederal Assembly:

Confederal Assembly by party, 1895
Governing coalition:

• The Conservative-Unionist Party (145 seats) came into existence with the merger of the dominant party in U.S. politics, the Unionist Party, and the Rupertian Conservative Party, and currently holds the most seats out of any party in the Confederal Assembly. Along with all other parties in the governing coalition and the official opposition, it holds a strong pro-Confederation stance. It has a strong populist and pro-military streak inherited from the Unionist Party, alongside a powerful public morality and Protestant stance from the Conservative Party that often weakens it among ethnic minorities in the Confederation.
• The Commonwealth Party (68 seats) profits greatly from the distaste of ethnic minorities and U.S. Southerners for the Conservative Unionists, using their agrarian populist policies to win over voters that would otherwise hold their noses and reluctantly vote for either the C-Us or the Democrats. They are, however, definitely to the left of the C-U on social issues, which tend to be the greatest source of discord in the coalition.
