The word "Makkasan" comes from "Makassar", the provincial capital of South Sulawesi, Indonesia. Since it was a place where Makkasan people lived in the past. 
Makkasan people are Muslims who migrated from Celebes to Siam since Ayutthaya period in the end of King Narai reign. Siamese in that time called them "Khaek Makkasan" (แขกมักกะสัน), for the word in Thai "khaek" literally guest, that refers to non-Westerners ("farang") or Christians mostly Muslims, Hindus or Indians or those from the Middle East and Malay Peninsula etc.
From the record of Claude de Forbin, a French naval who lived in Ayutthaya kingdom at the time, stated that the Makkasan rebels on July 14th, 1686. The suppression of Ayutthaya rulers with foreign aristocrat such as Constantine Phaulkon must used a harsh approach until it ended. But the cruel and terrible appearance of Makkasan was remembered by the Siamese to be compared to the Yaksa. The incident was called "Makkasan Rebellion" (กบฏมักกะสัน, ขบถมักกะสัน).
When the King Phutthayotfa Chulalok (Rama I) established Rattanakosin kingdom (today's Bangkok) in 1782, he allowed Makkasan people from Ayutthaya to settle in this area. It also was called "Makkasan" to the present.
