How did the Khmer Empire influence Southeast Asia and its cultural and architectural legacy? This book delves into the history of the Khmer Empire, which flourished in Southeast Asia from the 9th to the 15th century. It examines the Empire’s architectural achievements, particularly the construction of Angkor Wat, one of the largest religious monuments in the world, and the complex urban planning and hydraulic engineering systems that supported its vast empire. The narrative explores the cultural, religious, and political systems that underpinned the Khmer Empire, including the development of Khmer art, literature, and governance. By reflecting on the decline of the empire and its eventual rediscovery in the modern era, the book highlights the enduring legacy of the Khmer Empire in shaping the culture and identity of Cambodia and influencing regional architecture and urban planning.
