The “Alley of the Righteous Among the Nations” consists of two groves of trees, each planted in honor of residents of Odesa and Odesa Oblast who hid and saved Jews. The Righteous Among the Nations are non-Jews who risked their lives during the Holocaust. In 1953, the Israeli Knesset (parliament) passed the law “On the Perpetuation of the Memory of Martyrs and Heroes,” which resulted in the creation of the Yad Vashem memorial, and in 1963 the criteria for granting the title of Righteous Among the Nations were defined. Yad Vashem has a special commission that, based on documents, testimonies of survivors, and eyewitnesses, carefully examines each case and then decides whether it meets the strict criteria. The commission consists of historians, lawyers, and former victims of Nazism. Ukraine ranks fourth in the world in terms of the number of Righteous Among the Nations. On May 14, Ukraine will honor the memory of those people who risked their lives to save Jews during World War II.
