Not really an OTL map, also not really an alternate history map. This is simply a map based off of the famous play
Macbeth and what I was able to gleam from the setting and its pseudo-accuracy.
I know there are a few sections that I messed up on, Cumberland especially, however it is mainly a test of my style, trying to actually find it.
A Shakespeare-punk map could be quite interesting considering all of his pseudohistorical settings: Verona as an independent principality, Denmark being conquered by Norway, an Italian coast of Illyria...
You know, I never thought of that, maybe one day I'll try my hand at it. Of course, I'm sure there are others here that could do it more justice.
Honestly, Shakespeare has an interesting worldview if we merge his works into all one shared canon.
And let's not forget the shores of Bohemia.
(SF great Poul Anderson
wrote a novel on the theme, but was more interested in magic and the technological advancements implied in ancient Rome have clocks than in alt-geography)
That seems simple enough: either have the Bohemian crown conquer North through Poland (presumably with the help of their allies in Norway-Denmark) to the Baltic, or go south, conquering Austria (and thus eliminating them as a threat to Bohemian hegemony) and pick off the coastal Italian colonies that seem to dot the Illyrian coast. The only thing keeping the Bohemian Menace from overrunning Italy as a whole is the sturdy defenses put up by the Venetians...
Also worth noting: if King Lear is anything to go off of, Geoffrey of Monmouth's histories of Britain are likely more fact than fiction, meaning we can also add in some elements of the Arthur Romances.
Actually not needed, just let be kids of this guy (
https://en.wikipedia.org/wiki/Charles_IV,_Holy_Roman_Emperor) more lucky (only thing which stood between Charles Bohemia and sea was tiny Pomerania... guess from which country was Charlies last wife and mother of his son Sigismund?)
EDIT: and Charles... sister? Brothers daughter? Something like this... was duchess in Brabant (so no need to flood too much of Low Countries

)
I love the idea of a A Shakespeare-punk map.
As for Charles I winning the Civil War, I doubt even with magic he could win, and even so, the man was a self-destructive idiot who always chose the worst possible option every single time. And even if Charles won the first war, he just couldn't help himself when it came to making enemies and alienating allies. A second civil war would probably break out in another decade or so as his attitudes and policies are going to keep stirring up resentment and there's going to be an explosion at some point. (Or have Oberon and Titania back Parliament.)
Would be be cool to see is the affect Shakespeare magic would have on the world, and religion. (Fairies such as Oberon and Titania, Macbeth Witches, Ghosts, Roman Gods and Greek Deimigods, Amazonians, half-human, half-monsters like Caliban, warlocks like Prospero.)
Republic of Ragusa could be the Italian Illyrian coast. (Don't ask what happen to the Coats.)
Venice in this case won all it wars against the Ottomans, leading to a Venetian Aegean Sea and Greece, maybe even more. (Othello.) Ottomans get further screw over by the glory that is the Bohemian Empire.
The Union between Verona and Milan against the Bohemian Menace. (After they conquer the Papal States.)
With this Scotland, and a Norway that conquers Denmark, I could see a Scottish and Norwegian-Danish Canada and New England. (More if England is busy.) Same for Bohemian Colonial holdings.
I would think Gargoyles as well as Arthur Romances would make very good add on to the world. (King Arthur fighting the Saxons?)
Britain was never conquer by Rome, but rather stay a vassal of Rome, and later ally. (At least for a while.)
The Return of Antony and Cleopatra?
Shakespeare's sonnets would also be good to use. The Fair Youth, the Dark Lady, and the Rival Poet being like say immortals, or living personifications. (I already have in my mind the Dark Lady being this Carmen Sandiego figure.)
