It is uncertain which European nation arrived first in Barbados, which probably would have been at some point in the 15th century or 16th century. One lesser-known source points to earlier revealed works antedating contemporary sources, indicating it could have been the Spanish. Many, if not most, believe the Portuguese, en route to Brazil, were the first Europeans to come upon the island. The island was largely ignored by Europeans, though Spanish slave raiding is thought to have reduced the native population, with many fleeing to other islands.
