Narai in the context of "Mandarin (bureaucrat)"

The Ayutthaya Kingdom or the Empire of Ayutthaya was a Thai kingdom that existed in Southeast Asia from 1351 to 1767, centered around the city of Ayutthaya, in Siam, or present-day Thailand. European travellers in the early 16th century called Ayutthaya one of the three great powers of Asia (alongside Vijayanagara and China), although the Chinese chronicles recognise the kingdom as one of its tributary states. The Ayutthaya Kingdom is considered to be the precursor of modern Thailand, and its developments are an important part of the history of Thailand.

The name Ayutthaya originates from Ayodhya, a Sanskrit word. This connection stems from the Ramakien, Thailand's national epic. The Ayutthaya Kingdom emerged from the mandala or merger of three maritime city-states on the Lower Chao Phraya Valley in the late 13th and 14th centuries (Lopburi, Suphanburi, and Ayutthaya). The early kingdom was a maritime confederation, oriented to post-Srivijaya Maritime Southeast Asia, conducting raids and tribute from these maritime states. After two centuries of political organization from the Northern Cities and a transition to a hinterland state, Ayutthaya centralized and became one of the great powers of Asia. From 1569 to 1584, Ayutthaya was a vassal state of Toungoo Burma; but quickly regained independence. In the seventeenth and eighteenth centuries, Ayutthaya emerged as an entrepôt of international trade and its cultures flourished. The reign of Narai (r. 1657–1688) was known for Persian and later, European, influence and the sending of the 1686 Siamese embassy to the French court of King Louis XIV. The Late Ayutthaya Period saw the departure of the French and English but growing prominence of the Chinese. The period was described as a "golden age" of Siamese culture and saw the rise in Chinese trade and the introduction of capitalism into Siam, a development that would continue to expand in the centuries following the fall of Ayutthaya.

The Siamese embassy to France in 1686 was the second such mission from the Kingdom of Siam. The embassy was sent by King Narai and led by ambassador Kosa Pan. This embassy was preceded by the First Siamese Embassy to France, composed of two Siamese ambassadors and Father Bénigne Vachet [Wikidata], who had left Siam for France on January 5, 1684.

Constantine Phaulkon (Greek: Κωνσταντῖνος Γεράκης, Konstantinos Gerakis; γεράκι is the Greek word for "falcon"; also known as Costantin Gerachi, Capitão Falcão in Portuguese and simply as Monsieur Constance in French; 1647 – 5 June 1688) was a Greek adventurer who became chief minister to King Narai of the Ayutthaya Kingdom and assumed the Siamese noble title Chao Phraya Wichayen (Thai: เจ้าพระยาวิไชเยนทร์).

The Siamese revolution of 1688 was a major popular uprising in the Siamese Ayutthaya Kingdom (modern Thailand) which led to the overthrow of the pro-French Siamese king Narai. Phetracha, previously one of Narai's trusted military advisors, took advantage of the elderly Narai's illness, and killed Narai's Christian heir, along with a number of missionaries and Narai's influential foreign minister, the Greek adventurer Constantine Phaulkon. Phetracha then married Narai's daughter, took the throne, and pursued a policy of ousting French influence and military forces from Siam. One of the most prominent battles was 1688's Siege of Bangkok, when tens of thousands of Siamese forces spent four months besieging a French fortress within the city. As a consequence of the revolution, Siam severed significant ties with the Western world, with the exception of the Dutch East India Company, until the 19th century.

Kosa Pan (Thai: เจ้าพระยาโกษาธิบดี (ปาน), RTGS: Chao Phraya Kosathibodi (Pan); 1633 – 15 November 1699) was a Siamese diplomat and minister who led the second Siamese embassy to France sent by King Narai in 1686. He was preceded to France by the first Siamese embassy to France, which had been composed of two Siamese ambassadors and Father Bénigne Vachet, who had left Siam for France on January 5, 1684.
