Following the creation of the State of Israel and the ensuing war, Jordan seized the part of Palestine they named the West Bank. This included Ramallah. The West Bank was relatively peaceful during the years of Jordanian rule between 1948 and 1967, with its residents enjoying freedom of movement between the West Bank, Jordan, Lebanon, and Syria. Jordan annexed the West Bank, applying its national law to the conquered territory. However, many Palestinians were jailed for being members of "illegal political parties", which included the Palestine Communist Party and other socialist and pro-independence groups. By 1953, Ramallah's population had doubled, but the economy and infrastructure could not accommodate the influx of poor villagers. Natives of Ramallah began to emigrate, primarily to the United States. By 1956, about one fourth of Ramallah's 6,000 natives had left, with Arabs from the surrounding towns and villages (particularly Hebron) buying the homes and land the émigrés left behind.
