Chao Anouvong vs Rajasinha I

Chao Anouvong, king of Vientiane, launched a surprise attack on the Siamese city of Nakhon Ratchasima, seeking to reclaim Lao independence. The rebellion initially succeeded but was crushed by Siamese forces under King Rama III, leading to the destruction of Vientiane.

Siamese armies under General Bodindecha captured and systematically destroyed the city of Vientiane, including its temples and palaces. Thousands of Lao civilians were forcibly relocated to Siamese territory, ending the kingdom of Vientiane as a political entity.

After fleeing to the Vietnamese court of Emperor Minh Mang, Anouvong was handed over to Siamese authorities. He was publicly executed in Bangkok by being placed in a cage and exposed to the elements, dying after several days. His death marked the end of the Lao rebellion.

Rajasinha I's forces decisively defeated the Portuguese at the Battle of Mulleriyawa. This was the worst defeat inflicted on the Portuguese in Sri Lanka, nearly driving them from the island.

Rajasinha I converted from Buddhism to Hinduism, adopting the title 'Sivaguru'. This alienated many of his Buddhist subjects and led to internal unrest.

Following his conversion, Rajasinha I ordered the destruction of Buddhist temples and monasteries in his kingdom. This included the Temple of the Tooth in Kotte, which was burned down.

Rajasinha I laid siege to the Portuguese fort of Colombo for over a year. Despite his efforts, the siege failed due to Portuguese naval superiority and the arrival of reinforcements from Goa.
