According to the International Olive Council, to know the history of the olive tree, you have to go back to the twelfth millennium BC.

However, it was not until 1050 BC that the olive tree found its way to Spain through the Phoenicians.

The Spanish olive tree developed its full potential only after the Roman general named Publius Cornelius Scipio Africanus arrived in Spain in 212 BC.

The trees dominated Baetica Valley, and then afterward the Mediterranean region. 

The Arabs, during their trip to the southern part of Spain, have gifted Spain with several other varieties of olives.

No wonder the Spanish and Portuguese names for olives are directly connected to their Arabic counterparts:

English: olive / olive oil

Arabic: زيتون or zaytun

Spanish: aceituna / aceite

Portuguese: azeitona / azeite

The California Olive Committee recognizes the importance of Spain in the global spreading of olive tree planting.

The cuttings that the Spaniards brought to Peru around the 16th century paved the way for the appetite for olives to be embraced in America and beyond.
