This is my Bohemia turned HRE in 1594. A brief history of the past century or so, which so shaped European politics for centuries to come:
After the Regency Council 1490-9 traiterously converted to Protestantism before any major power except Sweden the
Great King (despite his rather mediocre stats)
Vaclav V of Bohemia King, Lord of Poland, Duke of Styria, Cologne, Saxony and Brandenburg, Earl of Luneburg, Salzburg and Meissen, Holy Roman Emperor (died Vaclav V, Holy Roman Emperor) had to beg and scrape to get his Empire back onside to pass the final two reforms, which he did in the early 1520s and 1530s after a bloody war (involving Castille) where much of the west escaped assimilation (Brabant was later annexed). One of the final acts in his great life was to abolish feudalism throughout his Empire.
The greatest loss in that diplomatic rupture with Catholic Europe was the century old Franco-Bohemian alliance, which had successfully dismantled Burgundy and turned it into the stub it is today. Somewhere in all this Great Britain collapsed without any obvious outside provocation.
Soon after Vaclav died the French declared war, and then lost (despite the aid of Northumberland
and Cornwall). Worried about French expanionism into the second colonial power Castille, the Emperor wisely attacked while they were recovering from such a conquest in Iberia (I fortunately gained a core in Bar just in time for a CB). These two wars have left the Emperor the clear leading power in Europe, but its rivals in the west remain a danger to long-term security.
Below is the Empire, turned to garish yellow with the help of Paint (minus a few islands I couldn't be bothered to fill). The Empire's possessions here include the eastern seabord of North America (with a slight Castilian interruption), the coast of South America, Imperial Maya (I was in the middle of taking them when the French invaded), the Caribbean, and Imperial West Africa (plus a bit in Benin). I am itching for militaristic colonial expansion (into Maya, Mali, India & Arabia), but I badly need to burn infamy.
The richest nation in the world. Muscovy was very briefly an ally of Bohemia, but has since set off on its own path. The Empire has little interest in eastern politics, despite having had the Ottomans on its doorstep for more than a hundred years.
Castille is still smarting from its war with France.
