Sri Vikrama Rajasinha was the last of four kings to rule the last Sinhalese monarchy of the Kingdom of Kandy on the island of Sri Lanka. The Nayak kings were Buddhists who spoke Tamil. The king was eventually deposed by the British under the terms of the Kandyan Convention, in 1815, ending over 2,300 years of Sinhalese monarchy on the island. The island was incorporated into the British Empire.
Yes, Sri Vikrama Rajasinha really was the King of Kandy. I like to think he lived at the top of a gumdrop-adorned Kandy Mountain surrounded by kandy kane fences, referred to his palace as Kandyland and snacked on only the finest kandy korn. This information is not verifiable via Wikipedia. But I did find that the British Empire declared war on the Kingdom of Kandy in 1815 and the king was exiled to India, never to return. In a related story, Candy told me nothing really matters anymore.
