History
Las Marías was founded on July 1, 1871. Don Benito Recio y Moreno was the acting mayor during the founding of Las Marías. Puerto Rico was ceded by Spain in the aftermath of the Spanish–American War under the terms of the Treaty of Paris of 1898 and became a colony of the United States. It remains so today.

On September 20, 2017 Hurricane Maria struck the island of Puerto Rico. In Las Marías, multiple landslides left highways covered in mud, trees and debris. In some areas of Las Marías there were more than 25 landslides per square mile due to the significant amount of rainfall and wind.
