"He was only eleven years old. His extreme youth and fondness for play, rather than politics or government, soon created discontent. Men of office saw that it was exposing their country to contempt, and sought for some one who might fill the place with dignity. The regent was long accustomed to all the duties of the government, and had enjoyed the confidence of their late venerable king; so, with one voice, the child was dethroned and the regent exalted under the title of Phra Chan Pra Sath-thong. This event occurred A.D. 1630," and forms the commencement of the third dynasty.
"The king was said to have been connected with the former dynasty, both paternally and maternally; but the connection must have been quite remote and obscure. Under the reign of the priest-king he bore the title Raja Suriwong, as indicating a remote connection with the royal family. From him descended a line of ten kings, who reigned at Ayuthia and Lopha-buri--Louvô of French writers. This line was once interrupted by an usurper between the fourth and fifth reigns. This usurper was the foster-father of an unacknowledged though real son of the fourth king, Chau Nárái. During his reign many European merchants established themselves and their trade in the country, among whom was Constantine Phaulkon (Faulkon). He became a great favorite through his skill in business, his suggestions and superintendence of public works after European models, and by his presents of many articles regarded by the people of those days as great curiosities, such as telescopes, etc.
"King Nárái, the most distinguished of all Siamese rulers, before or since, being highly pleased with the services of Constantine, conferred on him the title of Chau Phyá Wicha-yentrá-thé-bodi, under which title there devolved on him the management of the government in all the northern provinces of the country. He suggested to the king the plan of erecting a fort on European principles as a protection to the capital. This was so acceptable a proposal, that at the king's direction he was authorized to select the location and construct the fort.
"He selected a territory which was then employed as garden-ground, but is now the territory of Bangkok. On the west bank, near the mouth of a canal, now called Báng-luang, he constructed a fort, which bears the name of Wichayeiw Fort to this day. It is close to the residence of his Royal Highness Chau-fà-noi Kromma Khun Isaret rangsan. This fort and circumjacent territory was called Thana-buri. A wall was erected, enclosing a space of about one hundred yards square. Another fort was built on the east side of the river, where the walled city of Bangkok now stands. The ancient name Bángkok was in use when the whole region was a garden.[3] The above-mentioned fort was erected about the year A.D. 1675.
