1. Are the Protected states equal to the regular states or do they have more autonomy?
2. Why are Utah and Nevada one state?
3. When was slavery banned?
4. Why is Morocco independent?
The Nevada area is part of the greater state of Deseret, which IOTL did claim the area. Due to the USA's greater tolerance towards Mormons their territory wasn't reduced as much much as it was IOTL.
After Texas was admitted into the union an amendment was passed stating that any future state would have to be admitted as a free state. An equivalent of the American Civil War still happened, albeit in 1859, and was much shorter due to most states in the Upper South not seceding (only Florida, South Carolina, Georgia, Mississippi, Alabama, and Virginia seceded). So the slave states lost rather quickly and slavery was abolished in 1864 after a three year process to emancipate all slaves and to ensure that they would be properly compensated.
Morocco is independent for the same reason Ethiopia was in our timeline. It was considered to get turned into a protectorate but it put up a significant resistance (Ethiopia in our timeline also had the advantage that Italy, the only power interested in colonizing it despite its prestigious position as a Christian power in the very much non-Christian Africa, was incompetent in her attempts to do so). Also the United States attempted to weigh in, citing their old ties to the kingdom.
Seems the POD also effected how the Canadian provinces/Territories were divided No Yukon Territory, or maybe no NWT. The Quebec separation makes sense, there is very little up there. Manitoba seems to be split in half.
The Northwest Territory still exists, but it lacks the areas occupied by the Territory of Keewatin (formerly District of Keewatin), which is that nothern part of Manitoba. Canada in this timeline even has 4 territories: NWT, Keewatin, Ungava (northern Quebec) and the Arctic Islands Territory.
*Tries to examine it meanwhile* Hmmmmm, let's see. US still has some territories, not all full states, yet owns Baja California and Cuba (change in the war with Mexico?) yet not Alaska, Russia still is Tsarist (assumes this as Finnland is still part of it), Germany has still its eastern parts....if I'd take a guess we are somewhere in the mid 20s after a WW I where the US never entered the war and Germany was able to hold both sides of the front at bay and negotiate a peace treaty without loosing any territory (but also not gaining anything).
So I think the POD is somewhere after the American-Mexican war (Baja California) . But I cannot figure out how this would make America more idealistic. ^^
