after Adolf Hitler came to power but lived in it before the Nazis put the "Final Solution" into effect, or others who were not persecuted by the Nazis themselves, but were persecuted by their allies or collaborators both in Nazi satellite countries and occupied countries. Yad Vashem, the State of Israel's official memorial to the victims of the Holocaust, defines Holocaust survivors as Jews who lived under Nazi control, whether it was direct or indirect, for any amount of time, and survived it. This definition includes Jews who spent the entire war living under Nazi collaborationist regimes, including France, Bulgaria and Romania, but were not deported, as well as Jews who fled or were forced to leave Germany in the 1930s. Additionally, other Jewish refugees are considered Holocaust survivors, including those who fled their home countries in Eastern Europe in order to evade the invading German army and spent years living in the Soviet Union. The United States Holocaust Memorial Museum gives a broader definition of Holocaust survivors: "The Museum honors any persons as survivors, Jewish or non-Jewish, who were displaced, persecuted, or discriminated against due to the racial, religious, ethnic, social, and political policies of the Nazis and their collaborators between 1933 and 1945. In addition to former inmates of concentration camps, ghettos, and prisons, this definition includes, among others, people who lived as refugees or people who lived in hiding." In the later years of the twentieth century, as public awareness of the Holocaust evolved, other groups who had previously been overlooked or marginalized as survivors began to share their testimonies with memorial projects and seek restitution for their experiences. One such group consisted of Sinti (Gypsy) survivors of Nazi persecution who went on a hunger strike at Dachau, Germany, in 1980 in order to draw attention to their situation and demand moral rehabilitation for their suffering during the Holocaust, and West Germany formally recognized the genocide of the Roma in 1982. Another group that has been defined as Holocaust survivors consists of "flight survivors", that is, refugees who fled eastward into Soviet-controlled areas from the start of the war, or people were deported to various parts of the Soviet Union by the NKVD. The growing awareness of additional categories of survivors has prompted a broadening of the definition of Holocaust survivors by institutions such as the Claims Conference, Yad Vashem and the United States Holocaust Memorial Museum
