Dimitur Peshev and 40 other members of the Sobranje, the Bulgarian parliament, sign a petition demanding that deportations of Jews from Bulgaria to Occupied Poland end. Archbishop Kiril of Plovdiv sends a telegram to Tsar Boris III informing him of his intention to lie down on the tracks in front of any trains transporting Bulgarian Jews.
There relatively little anti-Semitism in Bulgaria and Jews have long been respected members of Bulgarian society. Jews are not treated as outsiders and foreigners, thus leaders of Bulgarian society are resist the Nazi demands that Jews be deported.
Because of Dimitur Peshev, Archbishop Kiril of Plovdiv, and Tsar Boris III, at the end of the World War II Bulgaria has about as many Jews as when the war started. This means that Bulgaria is able to protect its entire Jewish population by standing up to Hitler and the Nazis. Only Denmark will come close to saving as many.
Tsar Boris III makes inquiries about sending Bulgaria's Jews to Palestine instead of Poland. This doesn't make much sense unless he and others know or strongly suspect that Poland is a death sentence for Jews. The Nazis will only consider the plan in exchange for lots of money, reinforcing the idea that their goal is no longer just removing Jews from Europe, but exterminating Jews from the face of the Earth.
