The history of olive trees in Greece is not merely a botanical timeline; it is the history of the Greek people themselves.1 For over 5,000 years, the olive tree—often called “The Immortal Tree”—has been the cornerstone of Greek nutrition, economy, and spirituality.2
Prehistoric Origins and Early Cultivation
While the olive tree is native to the Mediterranean, Greece holds some of the oldest evidence of its presence on Earth.3
Fossil Records: Fossilized olive leaves found on the islands of Santorini and Evia date back between 50,000 and 60,000 years, proving that wild olive trees (oleasters) were part of the Greek landscape long before humans began farming them.4
Neolithic Domestication (c. 7000–3500 BC):5 Systematic cultivation likely began in Crete.6 Archaeological finds in the Gerani Cave suggest that Neolithic farmers were already processing olives as early as 4500 BC.7
The Minoan “Liquid Gold” (c. 3000–1100 BC): The Minoan civilization on Crete transformed olive oil into a commercial powerhouse.8 Linear A and B tablets found in palaces like Knossos record massive quantities of oil used for food, lamp fuel, and medicine.9 It was the Minoans who first exported oil to Egypt and the Levant, laying the foundation for Mediterranean trade.
The Classical Era: Mythology and Law
By the Golden Age of Athens (5th century BC), the olive tree was considered sacred.10 Its importance was reflected in every facet of life:
The Gift of Athena: According to myth, the goddess Athena and the god Poseidon competed for the patronage of Athens.11 Poseidon offered a saltwater spring, but Athena struck the rock of the Acropolis with her spear, and an olive tree sprouted.12 The citizens chose her gift for its endless benefits (food, oil, wood), and the city was named in her honor.13
Legal Protections: The Athenian legislator Solon enacted laws so strict that anyone caught uprooting or destroying an olive tree could face the death penalty.14 These trees were seen as public property and vital to the state’s survival.
The Olympic Spirit: At the ancient Olympic Games, the greatest honor was not gold, but the Kotinos—a simple wreath made from a branch of the sacred wild olive tree (Eleia Kallistephanos) planted by Heracles.15
Uses in Ancient Society
| Use Case | Description |
| Athletics | Athletes anointed their bodies with oil before training and competition to protect skin and highlight muscle. |
| Medicine | Hippocrates, the “Father of Medicine,” documented over 60 different uses for olive oil, from treating skin ailments to reducing inflammation. |
| Lighting | Clay lamps fueled by olive oil provided the primary source of light for homes and temples. |
| Rituals | Oil was used for anointing the dead, purifying altars, and as a sacred offering to the gods. |
Byzantine and Modern Eras
During the Byzantine Empire, Greece remained the world’s leading exporter of olive oil.16 In the 16th and 17th centuries, the development of soap-making in Europe (particularly in Marseille) created a massive new demand, prompting Greek regions like Crete and Lesvos to focus heavily on olive monoculture.17
The Landscape in 2026
Today, Greece remains the world’s third-largest producer of olive oil, but it ranks first in the quality of its yield, with roughly 82% of its production qualifying as Extra Virgin Olive Oil (EVOO)—the highest percentage in the world.18
Tree Population: There are approximately 140 million olive trees in Greece today.19
Ancient Survivors: Some trees, like the Olive Tree of Vouves in Crete, are estimated to be over 3,000 years old and still produce fruit today, serving as living bridges to the ancient world.20
Note: As of early 2026, Greek producers are increasingly focusing on “climate-resilient” farming techniques to protect these ancient groves from the rising temperatures of the Mediterranean basin.
