I second Historyman 14's Kievan Rus and Venice suggestions
The Navel of the Moon
Map #3 in the SuperSized Nations Series
(Yes, it has a name now)
The thicc maps continue with this threequel to And They Shall Eat Cake and How The Sausage Gets Made, this time zeroing in on a world where Mexico made sure to drink its milk and eat its Flintstone vitamins every day to get swole. The POD focuses not on New Spain, though, but rather a few innocuous British colonies on the Atlantic Coast. The American Revolution is seen as a rebellion ITTL, with the Battle of Saratoga failing miserably. This causes France to not get involved, however some callous missteps on the part of King Louis XVII lead to the nation still falling into anarchy and revolution. The American Rebellion is crushed, but revolution soon comes across the English Channel as King George III collapses into madness and Great Britain goes bankrupt due to heavily intervening in the French Revolution and the American Rebellion, causing a republic to be established in England and the British Royal Family to flee across the Atlantic and set themselves up in North America. Seeing a chance to strike, Spain declares war on the British royalists, and gains the Floridas and their Centroamerican and Caribbean holdings, further dooming Britain. Afterwards, though, similar events to those that sparked the American Rebellion go down: Spain needs to tax its colonies to fund the war, the colonies don't like that they're not able to influence the laws that are applied to them at all, and Latin America explodes much earlier, around 1785.
Unlike the American Revolution, the Latin American Revolutions result in the emergence of new empires and new monarchies. The House of Iturbide emerges in Mexico, which, ITTL, is made up of all claimed Spanish territories from OTL Alaska to Gran Colombia. Other stuff happens, the Roman Empire is reborn as a Catholic theocracy, Spain becomes Mexico's BFF, Austria unifies southern Germany, China gets taken over, there's a cultural genocide against Muslims (sadly, but considering the major powers of this world are all borderline theocratic Catholic empires, I think it's more than likely to occur), and Mexican hegemony over the globe is secured. This is the world in 1910. Russia, who got off pretty easily except for losing Vladivostok, and Prussia are both technically neutral, but they, as well as Brazil (still housing the Portuguese royal family, who fled after Spain took over the homeland), the United Kingdom of North America, Japan, Hungary, the Ottoman Empire, and every other still-independent nation is covertly working together, plotting to take down Mexico and company before it's too late.
Though, really, it already is.
EDIT: Oh yeah, that's Mexican Alsace-Lorraine, by the way.
(I'm willing to take suggestions again on the next country I should wank. Fire away!)
Here's the most up-to-date world map, which depicts DOL right after the end of the Edo War. This map also includes retcons that do not appear on previous maps, such as Genoa, British puppets states in North America, and an independent Kongo, which makes this the most accurate DOL map for the time being.
