Name
----

The city was named after St. John Baptist; *Maguana* is the Taíno name meaning "small valley". In the area, there were Taíno people living here before the Spanish invasion.

History
-------

The valley area of San Juan was the seat of Maguana whose leader was Caonabo. Caonabo in aboriginal language means "gran señor de la tierra or Great Lord of the Earth". Caonabo was the cacique or chief of the Taínos, upon the death of his uncle and became the most important and powerful ruler in Hispaniola at the time. He led the Taíno revolt against the Spanish invaders and was captured and died in a shipwreck while being taken to Spain as a prisoner. A brother of Caonabo and other allied Taíno caciques led the revolt against the Spanish and finally lost the battle in 1495.

San Juan de la Maguana was founded by the Spanish in 1503 by Diego Velázquez, who later went to conquest the island of Cuba, when Nicolás de Ovando was the Spanish governor of the island.

In 1606, those that were living in San Juan de la Maguana were ordered by the Spanish king to move to a place to the northwest of the city of Santo Domingo and the region was left without people for several years.

After the Dominican independence in 1844, there were some battles in this region between the Haitian and Dominican armies. The most important battle was the Santomé Battle on 22 December 1855 in a savanna to the west of the city where the Dominican army won the fight.
