John the Accidental
James the Expansionist
Zachary the Old, Rough and Ready

James the Lame but Loved
Ronald the Sun-President
George the Liar (read my lips)
William the Slick
George the Younger
Barack the African American
Donald the Tweeter

I'm sorry but.. Barack the Black?
 
Donald (Trump) the (wrote something and am kinda sad that we are so divided I can't say it).
Harry (Truman) the Hellgiver


UK

Teresa the Trapped (can't resign, can't get brexit passed)

Would they always need to be "the"? Sweyn Forkbeard didn't have an article in his nickname. Queen Mary was known as Bloody Mary. So we could go with OTL - "Give "em Hell Harry".

Huey Long was known as the Kingfish, so you also have cases of epithets that didn't use the given name.
 
Thatcher the Cruel
Major the Grey
Blair the Peace-Bringer (the Good Friday Agreement was signed then)
Brown the Dour
Cameron the Splitter (the Brexit referendum)
May the Unready

Because I just read a list of forty+ Presidents with "The" in it before I wrote it.
 
What I mean by this are rulers of various polities being given sobriquets that described their reign, more or less. Basically Louis XIV of France being the Sun King or Ivan IV of Russia being termed Grozny, which in English has the less nuanced equivalent "the Terrible".

What sorts of linguistic or cultural PODs would suffice to make it so that this styling lasts past the Napoleonic Era, when it seems that said epithets went out of fashion?

As I understand, this was done before the practice of using Roman numerals to count monarchs. It was a way of telling one King Charles or Louis or James apart from another. So how can the Roman numeral practice not catch on?
 
Queen Elizabeth "The Never Ending"
Queen Elizabeth "The Old"
Queen Elizabeth "The Charles Hater"
Queen Elizabeth "The Throne Denier"
Queen Elizabeth "The Ruler of Corgis"
