On April 30, Bulgaria remembers two events that connect the country with wider international history. One belongs to the unsettled diplomatic map after the First World War. The other is a story of mountaineering ambition, national pride, and the first Bulgarian success on one of the world’s highest peaks.
1919: Diplomatic relations with Ukraine are severed
On April 30, 1919, Bulgaria severed diplomatic relations with Ukraine. The relationship had been established in March 1918, during the turbulent final phase of the First World War and the revolutionary upheavals that followed the collapse of empires in Eastern Europe. Ukraine’s statehood was contested in a complex struggle involving local governments, foreign armies, Bolshevik forces, and shifting international recognition. Bulgaria’s short-lived diplomatic relationship with Ukraine therefore reflects the unstable diplomatic environment of the period, when new states and political projects appeared rapidly and often disappeared just as quickly. The date is a reminder that Bulgarian foreign policy was not isolated from the wider reordering of Europe after 1918. Even brief diplomatic episodes can reveal how Bulgaria navigated uncertainty, alliances, and recognition in a changing continental order.
1981: Bulgarian mountaineers scale Mt Lhotse
On April 30, 1981, Bulgarian mountaineers reached the summit of Mt Lhotse in the Himalayas, the world’s fourth-highest mountain at 8,516 metres. The ascent was part of the Bulgarian national expedition known as “Himalayas 81,” dedicated to the 1,300th anniversary of the founding of the Bulgarian state. Hristo Prodanov became the first Bulgarian to summit an eight-thousander and one of the few climbers to reach Lhotse without supplementary oxygen. The expedition demanded weeks of difficult preparation through dangerous terrain, high camps, extreme weather, and the hazards of the so-called death zone. The achievement entered Bulgarian sporting history as a landmark of endurance and ambition. It also prepared the ground for the later Bulgarian Himalayan tradition, including the dramatic 1984 Everest expedition in which Prodanov again became a national symbol.
