Sisaket, located in Thailand’s Lower Northeastern region, covers an area of approximately 8,840 square kilometers, with a population of around 1.45 million. Known for its rich cultural diversity, the province is home to ethnic groups speaking various local languages, including Lao, Kuy, Yoe, and Khmer dialects, and primarily practices Buddhism with traditions rooted in animism.
Human settlement in Sisaket dates back to prehistoric times, with significant development during the Khmer Empire, as seen in cultural sites such as ancient stone castles and Khmer-style temples. During the Ayutthaya period, the region was formally established as "Khukhan," named after the ancient rectangular temple, "Prasat Si Rectangle," now in Khukhan district. Later, in the reign of King Rama V of Rattanakosin, the provincial center was moved to present-day Sisaket town and retained the name Khukhan until it was designated as Sisaket Province in 1938.
Today, Sisaket is organized into 22 districts, including notable districts like Mueang Sisaket, Kantharalak, and Khukhan, each contributing to the province's historical and cultural tapestry. Sisaket remains a significant site for studying the legacies of the Khmer Empire, the Ayutthaya period, and Rattanakosin Thailand.
