Iraqi cuisine can be traced back some 10,000 years – to the Sumerians, Akkadians, Babylonians, Assyrians and Ancient Persians. Tablets found in ancient ruins in Iraq show recipes prepared in the temples during religious festivals – the first cookbooks in the world. Ancient Iraq, or "Mesopotamia", was home to many sophisticated and highly advanced civilisations, in all fields of knowledge – including the culinary arts. However, it was in the medieval era when Baghdad was the capital of the Abbasid Caliphate that the Iraqi kitchen reached its zenith. Today the cuisine of Iraq reflects this rich inheritance as well as strong influences from the culinary traditions of neighbouring Turkey, Iran and the Greater Syria area.
