A dish of stir-fried rice noodles is thought to have been introduced to the ancient Thai capital city of Ayuthaya by Viet traders[when?], and was subsequently altered to reflect the Thai flavor profile. The etymology of the dish's name in Thai suggest Chinese origins. Thai government Plaek Phibunsongkhram named pad Thai as part of campaign to promote Thai nationalism and centralization, seeking to reduce domestic rice consumption. The Thai economy was heavily dependent on rice exports, and the prime minister hoped to increase the amount available for export by encouraging Thais to make and sell rice noodles from street carts and in small restaurants.
As Thailand’s Prime Minister from 1938 to 1944 and from 1948 to 1957, Phibun amorously wanted modish and westernized Thai. In 1939 he changed the name of the country from Siam to Thailand. In that time noodles are very popular in Thailand but Plaek Phibunsongkhram wanted to get rid of everything that comes from China. One thing he cannot get rid is noodle. The government has an idea to create a new kind of food to replace Chinese noodle and establish the identity of Thailand. As a result he create a new noodles named ”Sen-Chan”. It is suitable for stir-fried in a pan (but china noodle often has a soup) and all of people know that and they was named this Thai noodle “Pad Thai”. The meats and vegetables in Pad Thai similar to food prepared by the Cantonese and Tae Chiew (Chao Zhou in Mandarin) from Guangdong province of China. However, the flavors and textures are pure Thai.
During the late 1930s and 1940s, Pad Thai was made popular in Thailand during World War II. The aftermath of Plaek Phibunsongkhram have been conceived as a kind of food and still exist to the present. Pad Thai has since become one of Thailand's national dishes. In present, some food venders put pork-chops for a more taste (but original recipe Pad Thai don’t have pork because government noticed that pork is a china meat) Some food venders still use original recipe until now. It used to be fast, delicious and nutritious food menu during a break of the day, And has become popular in many countries around the world.
