I like the fact that if you are a history lover in Czechia, you won’t have problems with finding a group of likeminded people nor events dedicated to a particular time period. I love 19th century and Jane Austen. And a few years ago I started visiting a local Jane Austen’s club’s events to make my dreams come true and live like in a period drama for a few hours.
Also if you are a Napoleon’s fan, you can visit the reenactment of the Battle of three Emperors in Tvarožná near Brno. But last year my friends and I decided to be a part of the games of Napoleon that took place in Austerlitz (Slávkov u Brna). There were dances, a picnic, a lot of talking and a lot of strolling. Take a look yourself!
PS. Here you can see photos from the Empire day in Olomouc in 2016.
