The modern territory of the Republic of Moldova was formed in August 1940 as the new Moldavian Soviet Socialist Republic (SSR). In 1941, when Germany invaded the Soviet Union, German-allied Romanian troops organized the deportation of the Moldovan Jews, and the Germans focused on their extermination. Up to 90,000 Jews, as much as one-third of the Jewish population, were killed on the territory of the Moldovan SSR. In 1992, Moldova passed a restitution law, but on its face, the law did not include Holocaust-era property confiscations. Moldova has not passed any special laws concerning the restitution of communal or heirless property. Moldova endorsed the Terezin Declaration in 2009 and the Guidelines and Best Practices in 2010.
