On April 30, 1981, Bulgarian mountaineer Hristo Prodanov achieved a historic milestone by becoming the first Bulgarian to summit Mount Lhotse, the world's fourth-highest peak at 8,516 meters, known for its treacherous terrain, severe weather, and deadly altitude. Prodanov accomplished this feat solo and without the use of supplemental oxygen, marking a significant moment in Bulgarian mountaineering history. ​

The ascent was part of the first-ever Himalayan expedition for Bulgaria and represented the country's first successful climb of an eight-thousander. Prodanov's achievement not only demonstrated exceptional physical endurance and mental fortitude but also placed Bulgaria among the elite nations in high-altitude climbing and inspired a generation of Bulgarian alpinists to follow in their footsteps.

Prodanov's solo ascent of Lhotse without supplemental oxygen was particularly noteworthy - even today, it remains a serious challenge for experienced mountaineers. 

The 1981 Bulgarian ascent stands as a symbol of courage and remains a significant chapter in the history of Himalayan mountaineering.
