What it is

Bucharest was the first city lit by refined petroleum, using kerosene lamps, and Romania the first country with crude oil output recorded in international statistics. It provided an outlet for the output of the Prahova valley.

Romania is often cited as the first country with official oil output in 1857 (275 t); the primacy of Bucharest's lighting is repeated in many sources and is not fully verified.

What it led to

  • the Ploiești and Moreni petroleum industry
  • kerosene exports to central Europe
  • urban lighting without gas or vegetable oil
