Retjenu, later known as Khor, was the Ancient Egyptian name for the wider Syrian region, where the Semitic-speaking Canaanites lived. Retjenu was located between the region north of the Sinai Desert and south of the Taurus Mountains in southern Anatolia. The term Retjenu was used to refer to this geographical area since the Middle Kingdom. The geographical area of Retjenu were defined during the New Kingdom and considered to have been a collection of small states ruled by princes. The boundaries of the area considered Retjenu shifted throughout time due to military, political, and economic factors. Retjenu was divided into two geographical regions. Djahy the southernmost region covered the area between Askalon and Mount Lebanon stretching inland to the Sea of Galilee. Amurru the northern region stretched between the Lebanon and Taurus Mountains. During Thutmose III's military campaigns in West Asia the area of Djahy was referred to as Upper Retjenu and generally covered the area of Canaan. Lower Retjenu was used to refer to the area of Amurru but also incorporated the cities located along Phoenician coast.

Canaan was a Semitic-speaking civilization and region of the Southern Levant in the Ancient Near East during the late 2nd millennium BC. Canaan had significant geopolitical importance in the Late Bronze Age Amarna Period as the area where the spheres of interest of the Egyptian, Hittite, Mitanni, and Assyrian Empires converged or overlapped. Much of present-day knowledge about Canaan stems from archaeological excavation in this area at sites such as Tel Hazor, Tel Megiddo, En Esur, and Gezer.
