Founded in 1885 as Berlin, by the residents of the previous "Gramalón" or "Agua Caliente" and by a German known as Serafin Brennen, who has arrived to establish the municipality, after surviving a shipwreck off the Salvadoran coast.

The name of Berlín came from Serafín Brennen, a German citizen who landed on the Salvadoran coast after surviving a shipwreck.

It is assumed that city used to be the place where Lencas lived, which settled in large numbers due to plenty of resources in the area.

Later, the Pipils arrived from the north and entered what is now the city of Berlin, crating cultural and linguistic influence to the area.

[5] On January 30, 1983, FMLN guerrillas entered Berlín and overthrew the municipality after several days of combat with government forces.

This gave a large turn in the civil war, since it was observed that many combats were now not just limited to the mountainous areas of Morazán, but also to important cities.

Battles in a city considered of great importance, due to it being located in an economically wealthy region, generated greater news impacts internationally and political concern in the Salvadoran Government and in the United States.

In the rural parts of Berlín, there is subsistence agriculture (minimal production only to supply the needs of a farmer and their family) consisting of corn and beans.

When there is a surplus production of basic grains (corn and beans), it is marketed mainly in the urban area of Berlín.

Lack of labor and income in municipalities with coffee-based economies led to economic, social and environmental consequences.

[14] This census does not consider, as mentioned before, the activities of the primary sector (Agriculture and farming) which in the case of Berlín, are the main economic base of the population.

Furthermore, due to jurisdictional issues, it does not take into account the electricity generator La Geo, which contributes to the employment and economic development of the municipality.

[16] The most popular landmarks in Berlín are the center park, which includes the Catholic church of San José built in 1897 and remodeled in 1947,[17] and the different old houses.
