The ancient Near East was home to many cradles of civilization, spanning Mesopotamia, Egypt, Iran, Anatolia and the Armenian highlands, the Levant, and the Arabian Peninsula. As such, the fields of ancient Near East studies and Near Eastern archaeology are one of the most prominent with regard to research in the realm of ancient history. Historically, the Near East denoted an area roughly encompassing the centre of West Asia, having been focused on the lands between Greece and Egypt in the west and Iran in the east. It therefore largely corresponds with the modern-day geopolitical concept of the Middle East.
