In 1837 King Phra Nang Klao made Prince Mongkut Abbot of Wat Pavaraniveca, situated close to the enceinte wall, in the northern part of the city. This monastery had been founded about ten years previously by Prince Cakti, who had been raised to the rank of Second King on the ascension of Phra Nang Klao, his nephew (1824–1832).
The dynasty which reigned during a part of the 13th and the first half of the 14th centuries at Sukhodaya and at Sri Sajjannlaya, on the upper Menam Yom, is the first historical Siamese dynasty. It has a double claim to this title, both because it cradle was precisely in the country designated by foreigners as "Siam" (Khmer: Syam; Chinese Sien, etc.), and because it is this dynasty which, by freeing the Thai principalities from the Cambodian yoke and by gradually extending its conquests as far as the Malay Peninsula, paved the way for the formation of the Kingdom of Siam properly so called.
