* By 1900, the entire British population was only 30% literate. For some reason, despite near-100% literacy in Britain proper, this meant that Britain never got around to figuring out how to colonize places. India and North America obviously were acquired by osmosis.
* Occupying the whole of the United States didn't mean that the CSA won the 3rd "Civil War". Rather, it decided to return to the status quo, ignoring the fact that the U.S. still owned the rest of the South.
* Not satisfied with trading privileges, it was the goal of the British to conquer as much of Western China as possible. Ironically, when the British finally got around to opening up sweatshops, there weren't nearly enough illiterate Chinamen to employ.
* The population of The United States of America was only around 20% American by 1910, owing to the fact that none of the massive number of immigrants chose to learn how to speak English.
* South American history is mostly extraordinarily boring, as the United States exerted such a strong influence over every Spanish-speaking country that none of them ever went to war. Unfortunately, since the French enthusiastically supported the Brazilians, this meant that Brazilian history is full of conquests, since the US never actually got around to intervening in any of the wars against its "allies".
* Very few countries were ever fully annexed, since doing so would have invoked such extreme foreign backlash that it wouldn't be worth it. Evidently the annexation of a country's other territories is only a minor issue.
* The Concert of Europe, which maintained general peace in Europe since the end of the Napoleanic Wars, dramatically came to a close when Austria, the chief proponent up until this point of the idea, entered into a massive war against Prussia in January 1836.
* The nation of Denmark is understood to be composed of the islands of Zealand, Funen, Lolland, Falster and Bornholm. Jutland, which was up until 1836 considered an integral part of Denmark, is now indistinguishable from the rest of Holstein and any silly ideas that it could have been full of Danes have been abandoned as ridiculous.
* The French province of Andalusia is now so full of French speakers that any notions of repatriating it on grounds of historical correctness or common culture have been abandoned. Spain seems to somehow retain its influence over the Philippines despite no longer possessing a navy.
* Nationalist movements of the 1800s were confined mostly to Prussians deciding that forming Germany hadn't been in their best interest. Slavs, Arabs, Indians, and other Asians were quite content to be under the thumb of autocratic governments that treated them like dirt.
* Egypt was torn apart by Spain and the Two Sicilies, but the Ottoman Empire never really got into the spirit of bringing its rebellious territories back into the fold.
