History of the Jews and Judaism in the Land of Israel

The history of the Jews and Judaism in the Land of Israel begins in the 2nd millennium BCE, when Israelites emerged as an outgrowth of southern Canaanites. During biblical times, a postulated United Kingdom of Israel existed but then split into two Israelite kingdoms occupying the highland zone: the Kingdom of Israel (Samaria) in the north, and the Kingdom of Judah in the south. The Kingdom of Israel was conquered by the Neo-Assyrian Empire (circa 722 BCE), and the Kingdom of Judah by the Neo-Babylonian Empire (586 BCE). Initially exiled to Babylon, upon the defeat of the Neo-Babylonian Empire by the Achaemenid Empire under Cyrus the Great (538 BCE), many of the Jewish exiles returned to Jerusalem, building the Second Temple.

In 332 BCE the kingdom of Macedonia under Alexander the Great conquered the Achaemenid Empire, which included Yehud (Judea). This event started a long religious struggle that split the Jewish population into traditional and Hellenized components. After the religion-driven Maccabean Revolt, the independent Hasmonean Kingdom was established in 165 BCE. In 64 BCE, the Roman Republic conquered Judea, first subjugating it as a client state before ultimately converting it into a Roman province in 6 CE. Although coming under the sway of various empires and home to a variety of ethnicities, the area of ancient Israel was predominantly Jewish until the Jewish–Roman wars of 66–136 CE. The wars commenced a long period of violence, enslavement, expulsion, displacement, forced conversion, and forced migration against the local Jewish population by the Roman Empire (and successor Byzantine State), beginning the Jewish diaspora.

After this time, Jews became a minority in most regions, except Galilee. After the 3rd century, the area became increasingly Christianized, although the proportions of Christians and Jews are unknown, the former perhaps coming to predominate in urban areas, the latter remaining in rural areas. By the time of the Muslim conquest of the Levant, Jewish populations centers had declined from over 160 to around 50 settlements. Michael Avi-Yonah says that Jews constituted 10–15% of Palestine's population by the time of the Sasanian conquest of Jerusalem in 614, while Moshe Gil says that Jews constituted the majority of the population until the 7th century Muslim conquest in 638 CE. Remaining Jews in Palestine fought alongside Muslims during the Crusades, and were persecuted under the Kingdom of Jerusalem.

In 1517, the Ottoman Empire conquered the region, ruling it until the British conquered it in 1917. The region was ruled under the British Mandate for Palestine until 1948, when the Jewish State of Israel was proclaimed in part of the ancient land of Israel. This was made possible by the Zionist movement and its promotion of mass Jewish immigration.
