In the last year of the existence of the Soviet Union, Ukraine participated in the union-wide referendum to preserve the Soviet Union in a different form made by Mikhail Gorbachev, while Georgia (aside from Abkhazia) did not. The next month, on April 9, Georgia declared independence from the Soviet Union while Ukraine, the second largest republic behind the Russian SFSR, did so on August 24 after the failed coup in Moscow two days earlier. Eventually, Ukraine held a referendum that took place on December 1 leaves with a 90% favor of independence. The secession ended the chances of the Union staying together, especially on a limited scale. The independence of both countries were recognized by the United States on December 25, 1991.
