- Simeon Petrov - Captain Simeon Petrov, Bulgarian Air Force, invented the world's first purpose-built air-to-surface bomb in 1912. The innovations included aerodynamically stabilized x-tail and an impact detonator. The majority of aircraft bombs to date follow Petrov's design. The Bulgarian Air Force deployed the original prototype, thus becoming the first military force in the world to conduct tactical airplane bombing in a full-scale war in 1912.

- Early Renaissance - The world famous frescos in the Boyana Church from 1239 AD have been described by Andre Grabar and many scholars, as Early Renaissance or precursors of Renaissance Art well before this period started in Italy. The murals are work of the unknown Boyana Master and his disciples who are believed to have been representatives of the Tarnovo Art School in the Second Bulgarian Empire (1185-1396 AD). The frescos have been compared to the work of Giotto who is generally considered the first in a line of great artists who contributed to the Italian Renaissance.
