Here is the explanation, I wish the person who posted this would have done the same. Aliyah is the immigration of Jews from the diaspora to the Land of Israel (Eretz Israel in Hebrew).....the opposite action, emigration from the Land of Israel, is referred to in Hebrew as yerida (decent). The state of Israel's Law of Return gives Jews and their Descendants automatic rights regarding residency and Israel citizenship. For much of Jewish history most of the Jews have lived in diaspora where Aliyah was developed as a national aspiration for the Jewish people, although it was not usually fulfilled until the development of the Zionist movement in the late nineteenth century.
Well, in this case Aliyah means the call to read from the Torah and has nothing to do with the State of Israel. The same term used for two different things!
