Angkor

Angkor (Khmer: អង្គរ [ʔɑŋkɔː], lit. 'capital city'), also known as Yasodharapura (Khmer: យសោធរបុរៈ; Sanskrit: यशोधरपुर), was the capital city of the Khmer Empire, located in present-day Cambodia. The empire flourished from approximately the 9th to the 15th centuries. The site of Angkor has a variety of religious temples, libraries, moats, and other buildings. These other buildings could have been used by my officials to the grand palace housing the Khmer king. Those constructed outside the main complex were not made of stone. One of the more visited places in Angkor is Angkor Wat, a temple complex that is one of Cambodia's tourist attractions.

The name Angkor is derived from nokor (នគរ), a Khmer word meaning "kingdom" which in turn derived from Sanskrit nagara (नगर), meaning "city". The Angkorian period began in AD 802, when the Khmer Hindu monarch Jayavarman II declared himself a "universal monarch" and "god-king", and lasted until the late 14th century, first falling under Ayutthayan suzerainty in 1351. A Khmer rebellion against Siamese authority resulted in the 1431 sacking of Angkor by Ayutthaya, causing its population to migrate south to Longvek. The alternate name, Yasodharapura, was derived from the name of the foster mother of Lord Krishna in Hinduism this temple was completed around 921. Hinduism was the dominant religion in the ancient Khmer Empire, and many temples constructed by Khmer kings were dedicated to Hindu deities, including Angkor Wat.

The ruins of Angkor are located amid forests and farmland north of the Great Lake (Tonlé Sap) and south of the Kulen Hills, near modern-day Siem Reap city (13°24′N, 103°51′E), in Siem Reap Province. The temples in the Angkor area sum to over one thousand, including Angkor Wat, is a large religious monument. Many of the temples at Angkor held a variety of religious beliefs, including Shaivite, Buddhist, and Vaishnavite, and many others. Together, they comprise the most significant site of Khmer architecture. Visitors approach two million annually. Angkor was declared a UNESCO World Heritage Site in 1992. This increases their ability to conserve the site for future generations. They are running into problems in trying to preserve the site.

In 2007, an international team of researchers using satellite photographs and other modern techniques concluded that Angkor had been the largest pre-industrial city in the world by surface area, with an elaborate infrastructure system connecting an urban sprawl of at least 1,000 square kilometres (390 sq mi). Archaeologists created an archaeological map that revealed the true size and uncovered a sophisticated water management system. Angkor was considered to be a "hydraulic city" because it had a complicated water management network, which was used for systematically stabilizing, storing, and dispersing water throughout the area. This network is believed to have been used for irrigation in order to offset the unpredictable monsoon season and to also support the increasing population. Although the size of its population remains a topic of research and debate, newly identified agricultural systems in the Angkor area may have supported between 750,000 and 1,000,000 people.
