[2] In English, the area is usually called Central Greece, but the equivalent Greek term (Κεντρική Ελλάδα, Kentrikí Elláda) is more rarely used.

It includes the southern part of the Greek mainland (sans the Peloponnese), as well as the offshore island of Euboea.

The region has traditionally been known as Roúmeli (Ρούμελη), a name deriving from the Turkish word Rūm-eli, meaning "the land of the Rūm [the Romans, i.e. the Byzantine Greeks]" and originally encompassing all of the Ottoman Empire's European possessions.

The official name Stereá Elláda ("Continental" or "Mainland" Greece) derives from the juxtaposition with the Peloponnese peninsula across the Corinthian Gulf, and the fact that these two territories formed the independent First Hellenic Republic after the Greek War of Independence (1821–1829).

[citation needed] The region is one of the most mountainous in Greece, having some of the highest elevations in the country.
