**San Cristóbal** is a Dominican city and the head municipality of the San Cristóbal province.

History
-------

Since colonial times, there were many farms in the region; the main crop was sugarcane. There were several sugar factories with slaves.

But the town was founded during the first years of the 18th century by a Catholic priest: Juan de Jesús Fabian Ayala y García.

In 1822, the town was made a municipality by the Haitian government. In 1844, after the Dominican independence from Haiti, the city was made a municipality of the old Santo Domingo province.

The first Dominican constitution was written in San Cristóbal in 1844.

In 1932, San Cristóbal was made the head municipality of the new Trujillo Province; it had the name of Trujillo after the dictator Rafael Trujillo who was born in San Cristóbal. After Trujillo's death, the province was given the name of the main city: San Cristóbal.
