Tsar Boris III assumed the throne after his father's abdication following Bulgaria's defeat in WWI. As WWII commenced, Bulgaria was at first neutral, but joined the Axis powers to reclaim territories that had been lost during the first war. In 1943, the Tsar refused Hitler's orders to deport the remaining Jewish population of Bulgaria. Boris III died the same year — shortly after a meeting with Hitler, giving rise to the speculation that he may have been poisoned. These 50% silver 100 leva coins were issued toward the latter part of the Tsar's rule. Very Fine quality.
