Vientiane during the Thonburi period, ten thousands of Lao people from Vientiane were deported to settle in Central Siam in Saraburi and Ratchaburi where they were known as the Lao Vieng (). The Lao elite class, including the princes who were the sons of the Lao king, were settled in Bangkok. In 1804, the Siamese-Lanna forces captured the Burmese-held Chiang Saen. Northern Thai inhabitants of Chiang Saen, which were by that time known as "Lao Phung Dam" (, the black bellied Lao), were relocated down south to settle in Saraburi and Ratchaburi. The greatest influx of Lao people came in 1828 after the total destruction of Vientiane, which was estimated to be more than 100,000 people. Through the early nineteenth century, there was a gradual Lao population shift from the Mekong region to the Chi-Mun Basin of Isan, leading to the foundation of numerous towns in Isan. In 1833, during the Siamese-Vietnamese War, the Siamese forces took control of Muang Phuan and its whole Phuan population were deported to Siam in order to curb Vietnamese influence.

In 1786, when Pattani was sacked, the Pattani Malays were deported to settle in Bangkok at Bang Lamphu. In the 1830s, Pattani and Kedah rebellions prompted deportations of 4,000 to 5,000 Malays from the south to settle on the eastern suburbs of Bangkok known as Saensaep and at Nakhon Si Thammarat in the aftermath.
