(Kibbutz Galuyot)
The concept that the exiled Jewish communities in the Diaspora would be gathered in Israel was derived from the Bible. The ingathering of the exiles became an important element in Zionism during the prestate period and was enshrined in the Law of Return passed by the Knesset after independence.
