Judea or Judaea is a mountainous region of the Levant. Traditionally dominated by the city of Jerusalem, it is now part of Palestine and Israel. The name's usage is historic, having been used in antiquity and still into the present day; it originates from Yehudah, a Hebrew name. Yehudah was a son of Jacob, who was later given the name "Israel" and whose sons collectively headed the Twelve Tribes of Israel. Yehudah's progeny among the Israelites formed the Tribe of Judah, with whom the Kingdom of Judah is associated. Related nomenclature continued to be used under the rule of the Babylonians, the Persians, the Greeks, and the Romans. Under the Hasmoneans, the Herodians, and the Romans, the term was applied to an area larger than the historical region of Judea. In 132 CE, the Roman province of Judaea was merged with Galilee to form the enlarged province of Syria Palaestina.

Palestine, officially the State of Palestine, is a country in the southern Levant region of West Asia. It encompasses two disconnected territories — the West Bank and the Gaza Strip, collectively known as the Palestinian territories — within the larger region of Palestine. The country shares its borders with Israel to north, west and south, Jordan to the east and Egypt to the southwest. It has a combined land area of 6,020 square kilometres (2,320 sq mi) while its population exceeds five million people. Its proclaimed capital is Jerusalem while Ramallah serves as its administrative center and Rafah is currently its largest city. Arabic is the official language. The majority of Palestinians practice Islam while Christianity also has a significant presence.
