Ferdinand II of Bohemia vs Rama III

Ferdinand II's policies as King of Bohemia, including the suppression of Protestantism, led to the Defenestration of Prague. Protestant nobles threw two Catholic regents from a window, sparking the Bohemian Revolt and the Thirty Years' War.

Ferdinand II's Catholic League forces defeated the Protestant army of Frederick V at White Mountain near Prague. This victory allowed Ferdinand to reassert Habsburg control over Bohemia and enforce Catholic uniformity.

Ferdinand II issued the Edict of Restitution, which ordered the return of all church lands seized by Protestants since 1552. This radical policy alienated many German princes and prolonged the Thirty Years' War.

Rama III succeeded his father, Rama II, as the third monarch of the Chakri dynasty. His reign marked a period of commercial expansion and cautious engagement with Western powers while maintaining Siamese sovereignty.

Rama III ordered the suppression of a rebellion led by Chao Anouvong of Vientiane. Siamese forces captured Vientiane, destroyed the city, and deported large populations to Siam, consolidating Siamese control over Lao territories.

Rama III signed the Burney Treaty with the British East India Company, establishing trade relations and defining spheres of influence in the Malay Peninsula. The treaty recognized Siamese suzerainty over Kedah while granting British commercial rights.

Rama III resisted Western demands for extraterritorial rights and military concessions, maintaining Siam's independence through diplomatic balancing. He also initiated limited modernization, including fortification upgrades and naval expansion.

Rama III launched a military campaign against Vietnam to assert Siamese influence over Cambodia. The war ended with a treaty that divided Cambodia into Siamese and Vietnamese spheres of influence, but failed to achieve lasting dominance.
