Isla de Mona History

Isla de Mona History

It is believed that the island was populated since the 12th century by the Taino. They lived in caves and used rock tools to survive.

Christopher Columbus was commissioned by the Spanish royal family to search for a sea route to the eastern spice islands. Unexpectedly, in 1492 he discovered the unknown continent of America.

During his second voyage in 1494, Columbus made a note of the island of Mona, near Puerto Rico. The island, approximately fifty square kilometers, was in a crucial position on the route between Europe and South America.

The island consists largely of chalk cliffs with underground corridors. These rocks contain fresh water, which suited the ships passing by. Drinking water was indispensable during a sea voyage and this island soon became an important stop for the Spaniards.

At the same time – in 1494 – one or more indigenous tribes lived on the coast of Mona. The island was a day’s canoe ride from the islands of Hispaniola (Now Haiti and the Dominican Republic) and Puerto Rico, and the population was part of a vast tribal network of hundreds of thousands of people, from the Bahamas to the Lesser Antilles.

They tilled small areas of land for agriculture, especially cassava roots, raised livestock, and hunted game and fish. They made bread from the cassava and the inhabitants immediately responded to the need for fresh water and food for European travelers.

With the arrival of the Spanish settlements, the indigenous tribes expanded their exports and supplied finished goods such as cotton garments and hammocks.
