30 Years War
I have a historical obsession for it.
To sum up what happen: half Europe decided that being protestant was good, and half decided it was not, so they fought over it like humans do.
King Gustav Vasa is a most peculiar charachter from that war. He was king of the (then uncucked) Swedes and apparently had the best army in Europe, organization-wise. Nicknamed ''Der Lewe Aus Mitternacht'' (The Lion From Midnight), he was a general badass.
And then he died at the Battle of Lutzen because he went full YOLO with a chavalry charge.
Also the Siege of Vienna and the Battle of Lepanto will both always have a special place in my historical heart.
What's yours most well remembered conflict (read as ''favourite''), chap?
