Bunnag family

Tomb of Sheikh Ahmed of Qom, in Ayutthaya.

Sheikh Ahmad, a Persian merchant, along with his brother Muhamad Sa-id and subordinates, settled in Siam around 1600.[1] Sheikh Ahmad was a native of Qom in Safavid Iran, south of Tehran. He established himself as a rich merchant in Ayutthaya. There he entered the service of King Songtham (1611–1628) who appointed him as Chao Kromma Tha Khwa (เจ้ากรมท่าขวา; Lord of the Right Pier) to supervise traders from the West, i.e. Persians, Indians and Europeans. He was also appointed Chularatchamontri (จุฬาราชมนตรี; Minister of Islamic affairs) to oversee all Shiites in Siam.

After subjugating a Japanese revolt under Yamada Nagamasa, Sheikh Ahmad became Samuha Nayok (First Prime Minister). Descendants of Sheikh Ahmad exerted control over Siamese politics, trade and foreign affairs. Many of them became Samuha Nayok. They also monopolized the post of Chularachamontri. All of them converted to Buddhism.

A man called Bunnag was a Buddhist descendant of Sheikh Ahmad. Bunnag married to Nuan, a daughter of wealthy Mon family from Bang Chan, situated near the mouth of Maeklong River.[2] Her sister Nak was the wife of Thong Duang. He was then kinsmen to Thong Duang. Though Thong Duang emerged as a powerful noble in Thonburi, Bunnag stayed far from the bureaucracy due to his childhood conflicts with Taksin.

Thong Duang then became Phutthayotfa Chulalok (Rama I), the first king of the Chakri dynasty in 1782. During the Nine Armies' Wars, Bunnag led the Siamese forces against the Burmese. He was then promoted and eventually became the Samuha Kalahom as Chao Phraya Akkaramahasaena.

Chao Phraya Akkaramahasaena was the primogenitor of the House of Bunnag. He sent his sons, including Tish and That, into the palace as the royal pages of Phutthayotfa Chulalok to gain an entrance into Siamese bureaucracy. Tish quickly rose to higher official ranks as Buddha Loetla Nabhalai favored the nobles from the Bunnag family and Tish's maternal family, the Bangchang. Tish then became the minister of Kromma Tha, supervising trade and foreign affairs under King Nangklao.

He was offered the position of Samuha Kalahom (Second Prime Minister) by the king, but Tish declined, saying that prime ministers died early. He then became Samuha Kalahom instead.

During the Siamese–Vietnamese Wars, Tish led the Siamese forces to Vietnam and imposed a naval blockade on Saigon. The campaigns were successful, however, and the war ended in 1845. With the death of Bodindecha in 1849, Tish remained the only powerful noble in the court.

Tish played a key role in the ascension of Mongkut, whether or not Nangklao intended to give the throne to his half-brother. The legend is that Nangklao wanted his son, Prince Annop, to succeed him, even giving Annop the bracelet passed down from his grandfather Phutthayotfa Chulalok. However, Dis switched the bracelet for a forged one, so the genuine one was not passed to Prince Annop. Tish lobbied for Mongkut, a monk of 27 years, to succeed the throne.

In 1851, when Mongkut had succeeded the throne, he made Tish Somdet Chao Phraya Borom Maha Prayurawongse and regent in the kingdom. Prayurawongse's brother, That, became Somdet Chao Phraya Borom Maha Pichaiyat and regent in Bangkok. The Somdet Chao Phraya title was the highest noble title, rivaling royalty. The first to hold the title, Maha Kshatriyaseuk, had become the first monarch of Chakri dynasty.

Mongkut gave much of his power to the regents he appointed. Prayurawongse was also competent in trade and foreign affairs and crucial to negotiating the Bowring Treaty.

Somdet Chao Phraya Borom Maha Sri Suriyawongse (Thai: สมเด็จเจ้าพระยาบรมมหาศรีสุริยวงศ์; Chuang Bunnag) was a prominent 19th-century Thai figure and served as the regent during the early years of the reign of King Chulalongkorn.

The eldest son of Tish Bunnag (Prayurawongse, สมเด็จเจ้าพระยาบรมมหาประยูรวงศ์) and than phu ying Chan, Chuang, was well educated. King Mongkut made him Samuha Kalahom, one of the two prime ministers of Old Siam.

After the death of King Mongkut in 1868, his young son Prince Chulalongkorn became the new monarch. However, as the new king was underage, Sri Suriyawongse was named as regent, a post he held until 1873. The Front Palace Crisis of 1874-5 changed the power dynamic in Siam, after which both Bunnag and noble influence waned.

Sri Suriyawongse died in 1883 in Ratchaburi. He was also the first Thai to have a life insurance policy after Chulalongkorn granted foreign companies permission to extend their insurance business into Siam.

His son Won Bunnag succeeded him as Samuha Kalahom and also held the title Chao Phraya Surawong Waiyawat.
