In Zionist discourse, the term "aliyah" (plural "aliyot") includes both voluntary immigration for ideological, emotional, or practical reasons and, on the other hand, mass flight of persecuted populations of Jews. The vast majority of Israeli Jews today trace their family's recent roots to outside the country. While many have actively chosen to settle in Israel rather than some other country, many had little or no choice about leaving their previous home countries. While Israel is commonly recognized as "a country of immigrants", it is also, in large measure, a country of refugees, including internal refugees. Israeli citizens who marry individuals of Palestinian heritage, born within the Israeli-occupied territories and carrying Palestinian IDs, must renounce Israeli residency themselves in order to live and travel together with their spouses.
