The olive tree, known scientifically as Olea europaea, is one of humanity’s oldest cultivated plants, symbolizing peace, prosperity, and endurance for over 8,000 years.
Ancient Origins
Olive trees trace their ancestry to the eastern Mediterranean, specifically the region between present-day Turkey and Syria, where DNA analysis has pinpointed the earliest domestication between 8,000 and 6,000 years ago. Archaeological finds—such as fossilized olive leaves and pits—date back to the 12th millennium BC, indicating that wild olives existed long before human cultivation began. By the Neolithic period (circa 4000–3000 BC), people in Syria and Palestine had begun to domesticate wild varieties.
Bronze Age and Classical Expansion
The olive soon became central to Mediterranean life. By 3000 BC, it was a cornerstone of Minoan civilization on Crete, contributing to its wealth and trade dominance. From the 16th to 12th centuries BC, Phoenicians carried the olive across the Mediterranean, to Cyprus, Greece, and later North Africa. The Greeks not only cultivated olives but wove them into mythology—Athena’s gift of the olive tree to Athens became a lasting cultural symbol.
The Romans greatly refined olive cultivation. During the Roman Empire, advanced grafting and pressing techniques spread throughout Europe, from Spain’s Baetica Valley to Gaul and North Africa. Olive oil became fundamental to Roman trade and daily life, used for food, lamps, and religious anointing.

Islamic and Medieval Influence
After Rome’s decline, Arab agronomists revived and expanded olive cultivation between the 8th and 15th centuries. Arabic terms for olive and oil—zeitun and zeit—influenced Iberian languages (aceituna, aceite), showing how vital the crop became in Al-Andalus (Moorish Spain). Olive oil became entwined with both Islamic and Christian ceremonial traditions, symbolizing purification, mercy, and sanctity.
Global Expansion
The Age of Exploration carried the olive plant beyond its Mediterranean home. In the late 15th and early 16th centuries, Spanish colonists brought olive cuttings to the Americas. By 1560, olive orchards were growing in Mexico, Peru, and Chile, later extending to California, Argentina, and beyond. The so-called Arauco tree in Chile, planted over 400 years ago, still bears fruit today.
Modern Cultivation and Symbolism
The olive tree remains a potent emblem of endurance and peace. As a saying often attributed to 18th-century naturalist Duhamel states: “The Mediterranean ends where the olive tree no longer grows.” Wherever sunlight and patience exist, the olive takes root and flourishes.
