In 1815, a group of residents, under the leadership of Don Juan José de la Torre, began the process to separate Morovis from Manatí.

In 1817, the government of Puerto Rico approved the separation, but it was not until 1818 that the requirements of a population of one thousand residents and the construction of a church and several other public buildings was fulfilled, that the municipality of Morovis was officially founded.

In 1822, the mayorship was constructed and in 1823, the new church was built, dedicated to Nuestra Señora del Carmen on lands donated by Don Juan Evangelista Rivera.

The phrase is believed by Puerto Ricans from outside of the town to have a negative connotation against moroveños, while, in reality, it is considered a positive motto.

[5] 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 territory of the United States.

In 1899, the United States Department of War conducted a census of Puerto Rico finding that the population of Morovis was 11,309.

[6] Morovis is a mountainous municipality with an area of approximately 100.3 square kilometres (38.7 sq mi), located slightly north of the center of the island,[7] which was hit particularly hard by Hurricane Maria on September 20, 2017.

Roads and bridges were impacted by landslides and flooding, and residents were left without access to electrical power, telecommunication services and basic necessities for many months.

[31] An Energy Consortium was signed in late February, 2019 by the mayors of Villalba, Orocovis, Morovis, Ciales and Barranquitas municipalities.

The Fiestas Patronales de Nuestra Señora del Carmen in honor of Our Lady of Mount Carmel is a religious and cultural celebration that generally features parades, games, artisans, amusement rides, regional food, and live entertainment.

[58] The coat of arms of the Municipality of Morovis is formed by an eagle in the left partition, which symbolizes Saint John the Evangelist and sings in honor of the founder of the town, Don Juan Evangelista Rivera.

The five cuatros observable in the right partition symbolize the fact that the town of Morovis is the main center of production of such typical Puerto Rican musical instruments.

The shield in the center represents the Order of the Carmelite Nuns, and symbolizes as well the Our Lady of the Carmen, matron of the town.
