During the late 19th and early 20th centuries, which region became the world's largest oil producer?

• A. Persian Gulf
• B. Texas and Gulf Coast
• C. Caspian Sea area
• D. Russia's Volga region

Answer: (C)

The region that became the world's largest oil producer in that era is the Caspian Sea area, especially around Baku. The late 1800s saw huge, easily accessible oil fields in this area, which could be drilled and brought to market quickly. Investment by European and Russian companies, combined with strong export routes via rail and ports, allowed very large volumes to be produced and shipped to growing industrial markets in Europe. This concentration of abundant supply in one geographic area, developed with the technology and infrastructure of the time, let the Caspian region outpace other regions such as Texas, the Persian Gulf, or the Volga area during that period. Later on, other regions would rise to dominance, but at that historical moment the Caspian Sea area stood out as the leading producer.
