It has a double claim to this title, both because its cradle was precisely in the country designated by foreigners as "Siam" (Khmer: Syain; 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.».
