Questions: While other Central American countries were called banana republics, this country was a coffee republic: Cuba Guatemala Mexico El Salvador

The answer is El Salvador.

Cuba is primarily known for its sugar production rather than coffee. While coffee is grown in Cuba, it is not the primary agricultural product that defines the country's economy.

Guatemala is indeed a significant coffee producer and is known for its high-quality coffee. However, it is also one of the countries often referred to as a "banana republic" due to the historical influence of banana companies on its politics and economy.

Mexico is a major coffee producer, particularly in regions like Chiapas and Veracruz. However, it is not typically referred to as a "coffee republic" in the same way as El Salvador.

El Salvador is historically known as a "coffee republic" because coffee was the dominant export and played a crucial role in its economy and political landscape, especially during the late 19th and early 20th centuries. Coffee production significantly influenced the country's social and economic structures.
