After the fall of the Khmer Empire in the 13th century, various states thrived in ancient Thailand, such as the various Tai, Mon, Khmer and Malay kingdoms, as seen through the numerous archaeological sites and artifacts that are scattered throughout the Siamese landscape. Prior to the 12th century however, the first Thai or Siamese state is traditionally considered to be the Buddhist kingdom of Sukhothai, which was founded in 1238 as you can see in Ancient Thailand map. Following the decline and fall of the Khmer empire in the 13th–15th century, the Buddhist Tai kingdoms of Sukhothai, Lanna and Lan Xang (now Laos) were on the ascension. However, a century later, the power of Sukhothai was overshadowed by the new kingdom of Ayutthaya, established in the mid-14th century in the lower Chao Phraya River or Menam area.

Ayutthaya expansion centred along the Menam while in the northern valley the Lanna Kingdom and other small Tai city-states ruled the area. In 1431, the Khmer abandoned Angkor after the Ayutthaya forces invaded the ancient city of Thailand. Thailand retained a tradition of trade with its neighbouring states, from China to India, Persia and Arab lands. Ayutthaya became one of the most vibrant trading centres in Asia as its shown in Ancient Thailand map. European traders arrived in the 16th century, beginning with the Portuguese, followed by the French, Dutch and English. After the fall of Ayutthaya in 1767 to the Burmese, King Taksin the Great moved the capital of Thailand to Thonburi for approximately 15 years. The current Rattanakosin era of Thai history began in 1782, following the establishment of Bangkok as capital of the Chakri dynasty under King Rama I the Great. According to Encyclopædia Britannica, "A quarter to a third of the population of some areas of Thailand and Burma were slaves in the 17th through the 19th centuries."

The losses initially included Penang and eventually culminated in the loss of four predominantly ethnic-Malay southern provinces, which later became Malaysia four northern states, under the Anglo-Siamese Treaty of 1909. In 1932, a bloodless revolution carried out by the Khana Ratsadon group of military and civilian officials resulted in a transition of power, when King Prajadhipok was forced to grant the people of Siam their first constitution, thereby ending centuries of absolute monarchy. During World War II, the ancient Empire of Japan demanded the right to move troops across Thailand to the Malayan frontier. Japan invaded the country and engaged the Thai Army for six to eight hours before Plaek Pibulsonggram ordered an armistice as its mentioned in Ancient Thailand map. Shortly thereafter Japan was granted free passage, and on 21 December 1941, Thailand and Japan signed a military alliance with a secret protocol wherein Tokyo agreed to help Thailand regain territories lost to the British and French.
