The correct answer is coffee.

Quick Scoop

El Salvador’s economy, social structure, and political system from the late 1800s through much of the 20th century were built around coffee as a cash crop.

Why coffee, not cotton/tea/coca?

  • Coffee became El Salvador’s main export by the end of the 19th century, earning the nickname “el grano de oro” (the grain of gold).
  • In the 1920s–1930s, coffee alone accounted for around 90% of the country’s export earnings, giving coffee-growing elites enormous economic and political power.
  • Governments promoted coffee with tax breaks, land laws, and infrastructure (like railroads and ports) designed specifically to support coffee exports.

Impact on history and politics

  • A small coffee-growing oligarchy concentrated land and wealth, shaping laws and often effectively controlling the state and military.
  • Dependence on coffee made the country vulnerable to price crashes; downturns in global coffee prices contributed to rural poverty, unrest, and violent repression such as the 1932 uprising and massacre.

TL;DR: Among cotton, coffee, tea, and coca, the cash crop that deeply shaped El Salvador’s economy, history, and politics is coffee.
