Aracibo (born c. 1480s) was a Taíno Cacique in Puerto Rico who governed the area which is now named after him (now spelled Arecibo).
Aracibo governed a tribe whose village was located by the shore of the river "Abacoa" (now known as the "Río Grande de Arecibo").
The rivers close to the village were full of fish and turtles and so it was only natural that the members of Aracibo's tribe were fishermen.
In 1511, Agueybana's brother Güeybaná, better known as Agüeybaná II (The Brave), discovered that the Spaniards were not "gods" and this encouraged the Cacique to rebel against the invaders.
In the year 1515, all of the area of Arecibo including the rivers of "Rio Grande" and "Tanama" were given as a gift to a Lope Conchillos (who resided in Spain) by the Spanish Crown.
