Torah portions on Shemini Atzeret is documented in the Talmud. That Talmudic source does not refer to the occasion as "Simchat Torah", but simply as [the second day of] Shemini Atzeret. The Simchat Torah celebration of today is of later rabbinic and customary origin. The day (but not the name) is mentioned in the siddur of Rav Amram Gaon (9th century CE); the assignment of the first chapter of Joshua as the haftarah of the day is mentioned there. The reading of the first section of Genesis immediately upon the conclusion of the last section of Deuteronomy—as well as the name "Simchat Torah"—can be found in the 14th century halachic work Arba'ah Turim. By the 16th century CE, most of the features of the modern celebration of Simchat Torah were in place in some form. The Simchat Torah celebration is now the most distinctive feature of this festival—so much so that in the Land of Israel, where Shemini Atzeret lasts only one day, it is more common to refer to the day as "Simchat Torah" than as "Shemini Atzeret". In the 20th century, Simchat Torah came to symbolize the public assertion of Jewish identity. The Jews of the Soviet Union, in particular, would celebrate the festival en masse in the streets of Moscow. On October 14, 1973, more than 100,000 Jews took part in a post-Simchat Torah rally in New York city on behalf of refuseniks and Soviet Jewry. Dancing in the street with the Torah has become part of the holiday's ritual in various Jewish congregations in the United States as well. In Israel, many communities conduct Hakafot shniyot, or "Second hakafot", on the day after Shemini Atzeret. In part, this shows solidarity with Jewish communities outside Israel, which are still celebrating Simchat Torah (on the second day of the festival). At the same time, it allows for a Simchat Torah celebration unconstrained by festival work restrictions, since the festival is over in Israel according to Jewish law. Outside Israel, where Shemini Atzeret is observed for two days, Simchat Torah is deferred to the second day, when all agree there is no obligation of sukkah. Carryover of Sukkot observances outside the Land of Israel In Israel—and for different reasons in Reform and Reconstructionist Judaism—none of the unique observances of Sukkot (sukkah, lulav and etrog) carry over to Shemini Atzeret. Shemini Atzeret is a holiday in its own right, without
