Judaization of Jerusalem (Arabic: تهويد القدس, tahweed il-quds; Hebrew: יהוד ירושלים, yehud yerushalaim) is a term used to describe the view that Israel has sought to transform the physical and demographic landscape of Jerusalem towards a fundamentally Jewish city under Israeli sovereignty. Often it is also referring to the increasing Jewish presence in Jerusalem in modern era, referring to Jewish Old Yishuv becoming dominant since Ottoman era and later the largest ethno-religious group in Jerusalem since mid-19th century and until the 1948 War, when Jordan cleansed Eastern Jerusalem from Jewish presence.
Throughout history, the demography of Jerusalem has undergone successive waves of Judaization, Hellenization, Romanization, Christianization, Arabization and Islamization during early Middle Ages, again Christianization during the Crusades, followed by another Islamization process under Ayyubid and Mamluk Sultanates. By early 16th century, Jerusalem was largely Muslim, but gradually gained Jewish and Christian populations - giving rise to the still existing division of the Old City of Jerusalem to Christian, Armenian, Jewish and Muslim Quarters. Since mid-19th century Jews had become the largest group in Jerusalem, which continued into British Mandate period and until the 1948 war.
At the conclusion of the 1948 Arab–Israeli War, Jordan occupied the Eastern part of Jerusalem while Israel controlled the Western part, resulting in a division of the city. On 2 August 1948, by declaration of the Minister of Defence, Israel applied its laws to the areas of Jerusalem under its control. Displaced peoples, both Arabs and Jews, were not allowed to cross the armistice lines to return to vacated homes. Jewish Israelis took possession of many of the vacant homes in Western Jerusalem and Palestinian refugees populated the Jewish quarter until it was evicted in the 1960s and 1970s.
