The Khmer Empire was one of Southeast Asia’s greatest civilizations, shaping the history, culture, architecture, and identity of Cambodia for centuries. Emerging in the early 9th century, the empire was traditionally founded by King Jayavarman II, who united territories and established a powerful kingdom known as Kambuja. From its early capital centers, Khmer rulers gradually expanded their influence across much of mainland Southeast Asia.
The empire reached its golden age under powerful kings such as Suryavarman II, who commissioned the magnificent Angkor Wat, and Jayavarman VII, who built Angkor Thom, the Bayon, hospitals, roads, reservoirs, and temples throughout the kingdom. At its height, the Khmer Empire controlled or influenced large areas of modern Cambodia, Thailand, Laos, and Vietnam.
Khmer civilization developed sophisticated irrigation systems, monumental architecture, sculpture, religion, trade, and administration. Hinduism and Buddhism both played important roles in royal and everyday life.
From the 13th century onward, the empire faced political struggles, economic pressures, environmental challenges, and growing competition from neighboring kingdoms. Angkor gradually declined, and by the 15th century, the Khmer royal center had shifted away from Angkor.
Although the empire eventually disappeared, its legacy remains extraordinary. Angkor’s temples, Khmer art, language, traditions, and cultural achievements continue to influence Cambodia and fascinate people around the world today.
