The fall of Angkor, also known as the sack of Angkor or siege of Angkor, was a seven-month siege of the Khmer capital Angkor by the Ayutthaya Kingdom. After the Khmer refused to recognize Ayutthaya authority, the Ayutthaya besieged Angkor and sacked the capital city. The Khmer King Ponhea Yat fled the city to Basan and later to Chaktomuk (in present-day Phnom Penh). Though the Khmer Empire was already in decline, the conquest of Angkor delivered the final blow and the empire fell. Angkor was subsequently abandoned. After the Fall of Angkor, the king moved the capital first to Basan and later to Chaktomuk, initiating the period known as the Post-Angkor period.
