Mary II of England vs Rama III

Mary II accepted the invitation from English parliamentarians to replace her father James II. She and her husband William of Orange invaded England with a Dutch fleet, forcing James II to flee. This bloodless transfer of power established parliamentary sovereignty over the monarchy.

Mary II was crowned joint sovereign with her husband William III at Westminster Abbey. She accepted the Bill of Rights, which limited royal powers and affirmed parliamentary authority. This coronation formalized the new constitutional arrangement.

Mary II served as regent while William III campaigned in Ireland against James II's forces. She effectively governed England, managing the Treasury and military logistics. Her regency demonstrated her administrative competence and maintained stability.

Mary II died of smallpox at Kensington Palace at age 32. Her death deeply affected William III and the nation. She was buried in Westminster Abbey. Her early death ended her joint reign and left William as sole monarch.

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.
