Fiat money is government-issued currency, usually created by a central bank and made legal tender by regulation, but not backed by gold, silver or any other commodity. Since the Jamaica Accords ended the Bretton Woods system in 1976, every major government currency is fiat money. Its value rests entirely on shared trust: people use it as a unit of account and a medium of exchange because they expect merchants and others to accept it for payment. Fiat money looks like older paper that was redeemable for metal, but it has no such claim. The term fiat comes from Latin for let it be done, meaning an order or decree. Government-issued banknotes of this kind first appeared in China in the 13th century.

Israeli reports also say the cabinet directed the military to prepare for a possible new attack on Iran.

Angkor, near Siem Reap in northern Cambodia, was the capital of the Khmer Empire, which ruled much of mainland Southeast Asia between roughly the 9th and 15th centuries. At its height the city spread across about 3,000 square kilometres, making it the largest pre-industrial city on Earth by area. Its growth depended on water: huge reservoirs called barays, along with canals and embankments, stored monsoon rain and carried it to rice fields. That system let farmers harvest more than once a year and fed a very large population through the dry season. The temple complex of Angkor Wat, built in the early 12th century, is the best-known monument and still stands at the heart of the park.
