Calabria is a region in Southern Italy. It is a peninsula bordered by Basilicata to the north, the Ionian Sea to the east, the Strait of Messina to the southwest, which separates it from Sicily, and the Tyrrhenian Sea to the west. With almost 2 million residents across a total area of approximately 15,222 km² (5,877 sq mi), it is the tenth most populous and the tenth largest Italian region by area. Catanzaro is the region's capital, while Reggio Calabria is the most populous city in the region.

Calabria is the birthplace of the term Italy, given to it by the Ancient Greeks who settled in this land starting from the 8th century BC. Thanks to its strategic position in the center of the Mediterranean Sea, the region became the center of Magna Grecia (Greater Greece), with the foundation along its coasts of many Greek city-states (póleis) that remained for centuries among the richest and most culturally advanced of their time. Calabria is where Pythagoras, one of the fathers of Western philosophy, developed and spread his thought. It is also the birthplace of Milo, the greatest champion of the ancient Olympic Games, and the adoptive homeland of Herodotus, one of the greatest historians of all time.

In Roman times it was part of the Regio III Lucania et Bruttii, a region of Augustan Italy. After the Gothic War, it became and remained for five centuries a Byzantine dominion (Duchy of Calabria, later promoted to Theme), fully recovering its Hellenic character on a linguistic, religious and artistic level. Cenobitism flourished, with the rise in the whole peninsula of countless churches, hermitages and monasteries in which multitudes of Basilian monks were dedicated to the transcription of classical and religious texts. The Byzantines introduced the art of silk in Calabria and made it the main silk production area in Europe. In the 11th century, the Norman conquest started a slow process of Latinization.

It is the birthplace of two of the most influential European philosophers of the 16th century, Bernardino Telesio and Tommaso Campanella.

In Calabria there are three historical ethnic minorities: the Griko people, speaking Calabrian Greek (also known as Grecanico), a local variety of the Greek language with some unique and archaic features; the Arbëreshë people, descendants of Albanian refugees who fled Albania between the 14th and the 18th centuries following the Ottoman conquest of the Balkans; the Occitans of Guardia Piemontese, a village founded in the 12th century by Waldensians coming from the Western Alps. This extraordinary linguistic diversity makes the region an object of study for linguists from all over the world.

Three national parks are found in Calabria: the Pollino National Park (which is the largest in the country), the Sila National Park and the Aspromonte National Park. This, combined with a large number of beaches, small villages, archaeological parks and ancient castles, makes the region a tourist destination.
