Bulgaria - 1930 - 5 Leva (VF) - Boris III was the Tsar of Bulgaria from 1918 to 1943, ascending the throne after World War I. He steered Bulgaria through political upheavals, overthrew the 1934 Zveno coup to rule as a de facto absolute monarch, and aligned with the Axis in World War II to regain territories. He resisted sending troops against the Soviet Union and blocked deportations of Bulgarian Jews, though Jews from occupied lands were sent to Nazi camps. He died suddenly in 1943 after meeting Hitler, amid speculation over poisoning.
