Charles IV vs Tarmashirin

Charles IV, as King of Bohemia and Holy Roman Emperor, established Prague as the permanent imperial capital. He initiated extensive building projects including the Charles Bridge and St. Vitus Cathedral, transforming Prague into a major European cultural and political center.

Charles IV founded the University of Prague, later named Charles University, as the first university in Central Europe. It became a leading center for learning and attracted scholars from across the continent, strengthening Prague's intellectual reputation.

Charles IV issued the Golden Bull, a constitutional document that regulated the election of the Holy Roman Emperor by seven prince-electors. This law stabilized imperial succession and defined the electoral process for centuries, reducing papal influence.

Charles IV secured the Margraviate of Brandenburg for the Luxembourg dynasty through a treaty with the Wittelsbachs. This territorial acquisition expanded his family's holdings in northern Germany and strengthened imperial authority.

Tarmashirin converted to Islam, becoming the first Chagatai khan to adopt the religion. This conversion influenced the religious orientation of the Chagatai Khanate and led to tensions with traditionalist Mongol factions who opposed Islamic influence.

Tarmashirin was deposed and killed by a rebellion led by traditionalist Mongol nobles who opposed his Islamic policies and perceived abandonment of Mongol customs. His death ended his reign and marked a period of instability in the Chagatai Khanate.
