Originating in the Mediterranean region, olive trees have been cultivated for more than 6,000 years. The olive tree was highly valued by ancient societies, such as the Greeks and Romans, for their fruit, which was extracted and used to make olive oil, which was a vital part of their diets, economics, and customs.

Olive oil was highly valued in ancient Greece for its applications in medicine, beauty, and religious rituals in addition to its gastronomic usage. The Greeks used it topically and internally after realizing its nutritional advantages and medicinal qualities. In a similar vein, olive oil was highly prized by the Romans for its use in cooking, as lamp fuel, and as a symbol of prosperity.

During the Roman Empire, olive oil production and trade grew throughout Europe, North Africa, and the Middle East. Olive oil production methods changed over time, moving from stone grinding in antiquity to hydraulic presses in the Middle Ages and finally to contemporary mechanical extraction systems.

Nowadays, the majority of the world’s olive oil is produced in Mediterranean nations like Tunisia, Greece, Italy, and Spain, where it is still a staple of regional cuisine and cultural heritage.
