Petar I of Serbia vs Sri Vikrama Rajasinha

Petar I became King of Serbia in June 1903 after the assassination of Alexander I and the end of the Obrenovic dynasty. His accession restored the Karadjordjevic dynasty to the throne.

Petar I led Serbia during the First and Second Balkan Wars (1912-1913), which resulted in significant territorial expansion. Serbia gained Kosovo, Macedonia, and parts of Albania, doubling its territory.

Petar I led Serbia through World War I after the Austro-Hungarian invasion in 1914. Despite initial victories, Serbia was overrun in 1915, and the king led the army and government in exile on Corfu.

Petar I was proclaimed King of the newly formed Kingdom of Serbs, Croats, and Slovenes in December 1918. This united South Slavic peoples into a single state, later known as Yugoslavia.

Sri Vikrama Rajasinha became the last king of the Kandyan Kingdom at age 18, succeeding his uncle Rajadhi Rajasinha. His reign was marked by internal factionalism and growing British influence in the coastal regions of Ceylon.

Sri Vikrama Rajasinha executed his chief minister Pilimatalawe, who had conspired with the British. This act intensified internal dissent and alienated powerful Kandyan nobles, weakening the kingdom's unity.

British forces invaded the Kandyan Kingdom in January 1815. Sri Vikrama Rajasinha's army was defeated due to internal betrayal by Kandyan nobles who signed the Kandyan Convention with the British, ending the kingdom's independence.

Sri Vikrama Rajasinha was deposed by the British and exiled to Vellore, India, along with his family. This marked the end of the Nayakkar dynasty and the Kandyan Kingdom, as Ceylon became a unified British colony.
