I realize that nationalism was mainly a 19th century phenomenon, but is there any way that the Kingdom of Bohemia could've declared its independence when choosing Frederick V of the Palatinate as their king (or rather, maintained their independence against the Habsburgs under the Palatine Wittelsbach dynasty, post-1619/1620)? Can the Bohemian kingdom hold its own against Vienna? And what might be the effects of it maintaining/achieving its independence?
