Southern Greece in the context of "Peloponnese"

The Peloponnese Region (Greek: Περιφέρεια Πελοποννήσου, romanized: Periféria Peloponnísou, [periˈferia pelopoˈnisu]) is a region in southern Greece. It borders Western Greece to the north and Attica to the north-east. The region has an area of about 15,490 square kilometres (5,980 square miles). It covers most of the Peloponnese peninsula, except for the northwestern subregions of Achaea and Elis which belong to Western Greece and a small portion of the Argolid peninsula that is part of Attica.

Kythira Strait (also Kythirian Straits, Kythira–Antikythira Strait or Kithera Channel) is a waterway off Kythira in Southern Greece. The Kythira–Antikythira Strait is situated within the Western Hellenic arc. It measures approximately 100 kilometres (62 mi) in length and is situated between the Peloponnese and the island of Crete.

Many ships have sunk in the area, including HMS Greyhound (H05), HMS Gloucester (62), and SS Ivernia.

The Aegean Sea plate (also called the Hellenic plate or Aegean plate) is a small tectonic plate located in the Eastern Mediterranean under Southern Greece and western Turkey. Its southern edge is the Hellenic subduction zone south of Crete, where the African plate is being swept under the Aegean Sea plate. Its northern margin is a divergent boundary with the Eurasian plate.

The seafloor in this region is about 350 m below sea level, while the adjacent Black Sea and Mediterranean Sea are 1300–1500 m deep. For this reason it is considered a high plateau between the seas. Evidence suggests the Aegean plate contains thinned continental crust, rather than oceanic crust. Since its creation the crust has been thinned through various processes, including post-orogenic collapse and crustal extension. This extension is responsible for the formation of the Gulf of Corinth.

The Kingdom of the Morea or Realm of the Morea (Italian: Regno di Morea; Venetian: Regno de Morea; Greek: Βασίλειον του Μορέως, romanized: Vasíleion tou Moréos) was the official name the Republic of Venice gave to the Peloponnese peninsula in Southern Greece (which was more widely known as the Morea until the 19th century) when it was conquered from the Ottoman Empire during the Morean War in 1684–99. The Venetians tried, with considerable success, to repopulate the country and reinvigorate its agriculture and economy, but were unable to gain the allegiance of the bulk of the population, nor to secure their new possession militarily. As a result, it was lost again to the Ottomans in a brief campaign from June to September in 1715.

Gytheio (Greek: Γύθειο [ˈʝiθio]) or Gythio, also the ancient Gythium or Gytheion (Ancient Greek: Γύθειον), is a town on the eastern shore of the Mani Peninsula in the Peloponnese of southern Greece, in the historical and administrative region of Laconia. It is the largest and most important town in Mani. Gytheio is the seat of the municipality of East Mani. Gytheio is significant in the history of Mani and the Maniots.

Ancient Gytheio was the seaport of Ancient Sparta, approximately 40 kilometres (25 miles) north. Gytheio continued to be a major port until its destruction in the 4th century CE, possibly by an earthquake. Its strategic location made it a coveted possession for foreign powers into the 20th century.

Arvanitika (/ˌɑːrvəˈnɪtɪkə/; Arvanitika: αρbε̰ρίσ̈τ, romanized: arbërisht; Greek: αρβανίτικα, romanized: arvanítika), also known as Arvanitic, is the variety of Albanian traditionally spoken by the Arvanites, a population group in Greece. Arvanitika was brought to Southern Greece during the late Middle Ages by Albanian settlers who moved south from their homeland in present-day Albania in several waves. The dialect preserves elements of medieval Albanian, while also being significantly influenced by the Greek language. Arvanitika is today endangered, as its speakers have been shifting to the use of Greek and most younger members of the community no longer speak it.
