Q & A

What role did water management play in the success of Angkor civilization?

Water management was critical to Angkor’s success, as the city developed advanced systems of reservoirs and canals to store excess rainwater during the wet season and distribute it during the dry season. This enabled them to sustain agriculture, particularly rice farming, which supported a large urban population and contributed to the empire's dominance.

How did the climbers help preserve Angkor Wat?

The climbers worked at heights of up to 65 meters above the ground, removing invasive plants growing on the temple. They applied poison to prevent the roots from sprouting again, thus protecting the structure from damage caused by plant growth.

What technological solution did the Angkor civilization develop to manage water supply?

The Angkor civilization developed an extensive hydraulic system, including large reservoirs and a network of canals. This system stored excess rainwater during the wet season and then distributed it during the dry season, ensuring a stable water supply for agriculture and the city.

What event in the sky was used by Angkor kings to demonstrate their divine right to rule?

The kings of Angkor used a celestial event when sunlight aligned perfectly with the temple towers, casting a beam of light onto a pedestal in the ceremonial chamber. This event, which occurred twice a year, was believed to demonstrate the king's connection to the gods.

What caused the downfall of the Angkor civilization?

The downfall of the Angkor civilization is largely attributed to a combination of factors, including a shift in religious practices (from Hinduism to Buddhism), neglect of their water management system, and a severe drought. The drought, lasting up to 30 years, overwhelmed the already fragile water infrastructure and led to agricultural failure, which contributed to the collapse of the empire.

How do researchers use tree rings to study the history of Angkor?

Researchers use dendrochronology, or tree ring dating, to reconstruct past climate conditions. By analyzing tree rings from ancient trees found in the region, they can determine rainfall patterns over hundreds of years, providing crucial evidence of droughts that occurred towards the end of the Angkor period.

What are the main differences between the religious practices of Angkor and the Maya regarding kingship?

Both the Angkor and Maya civilizations viewed their kings as divine, but Angkor kings were directly associated with Hindu cosmology and believed to be gods. In contrast, the Maya kings were not necessarily seen as gods but were central to religious ceremonies and astronomy. Both civilizations, however, incorporated astronomical knowledge into their religious practices.

What is the significance of the ancient canal system in Angkor's success?

The canal system in Angkor was part of the city's water management infrastructure, crucial for controlling water flow to rice fields and ensuring a stable agricultural environment. The canals allowed for the distribution of water from the reservoirs to maintain farming during both wet and dry seasons, which helped sustain the empire.

Why did the water management system in Angkor eventually fail?

The water management system in Angkor failed due to a combination of neglect and environmental challenges. The shift from Hinduism to Buddhism in the 13th century might have led to reduced investment in maintaining the hydraulic system. Additionally, long periods of drought, identified through tree ring studies, exacerbated the situation, rendering the system incapable of supporting the city.

How did the use of technology in Angkor affect the city’s expansion?

The use of advanced technology, such as hydraulic engineering, enabled Angkor to expand into more marginal areas by making previously less fertile land arable. However, this reliance on technology also created dependencies that became problematic when the hydraulic system eventually failed, contributing to the city's collapse.
