As the eldest surviving legitimate son of Rama I, Prince Itsarasunthon succeeded to throne when Buddha Yotfa Chulaloke died in 1809. No royal naming system was established at the time Rama II was crowned. He was later named by his son Nangklao as Loetlasulalai but changed to Loetlanaphalai by his another son Mongkut and by the Rama convention, called Rama II. His consort, Princess Bunrod, was raised to Queen Sri Suriyendra. As soon as Loetlanaphalai ascended the throne, Prince Kshatranichit, the surviving son of Taksin, rebelled as pretender to the throne. Loetlanaphalai's son, Prince Tub effectively crushed the rebellion, proving himself to be competent, thus gaining his father's favor. Prince Tub was raised to Kromma Muen, given the Sanskrit-derived name Jessadabodindra, and made Minister of Foreign Affairs. Countering the Burmese invasions The Konbaung king Bodawpaya, seeing that Rama I was dead, marched an army into Chumphon and conquered Thalang (Phuket City) in the same year. Loetlanaphalai sent his brother Maha Senanurak the Front Palace to recapture Thalang, which had been razed to the ground. This "Thalang campaign" was the last invasion by the Burmese into Thai territory. Culture and literature It was said that during Rama II's reign, if one could write a refined piece of poetry, then one would be able to become a royal favorite, as Loetlanaphalai himself was a poet. The reign was a cultural renaissance after the massive wars that plagued the First Reign; particularly in the fields of arts and literature. Poets employed by Rama II included Sunthorn Phu the drunken writer (Phra Aphai Mani) and Narin Dhibet (Nirat Narin). His sons, Jessadabodindra and Paramanuchitchinorot, were encouraged to excel in poetry. Poramanuchit later became a Sangharaj (Buddhist hierophant) and was well known for his religious works. Rama II's reign saw the reconstruction of Thai culture and royal traditions. In 1811, the grand royal funeral was held for King Rama I. In the same year, a cholera epidemic broke out in Bangkok. Loetlanaphalai ordered Apat Pinat or sickness-repelling ceremonies to be performed. He also established the education and the examination system of Buddhism by dividing it into nine levels. In 1817, the Vesak festival was restored. Foreign relations In 1810, the first Rattanakosin-to-China mission was sent to the Jiaqing Emperor. Since the Siamese revolution of 1688, Western presence had been reduced to a small scale as the Thai Kings ceased to encourage foreign influence. This, coupled
