"Aliyah" is an important Jewish cultural concept and a fundamental component of Zionism. It is enshrined in Israel's Law of Return, which accords any Jew (deemed as such by halakha and/or Israeli secular law) and eligible non-Jews (a child and a grandchild of a Jew, the spouse of a Jew, the spouse of a child of a Jew and the spouse of a grandchild of a Jew), the legal right to assisted immigration and settlement in Israel, as well as Israeli citizenship.
