Ancient Elis in the context of "Tyro"

The Second Peloponnesian War (431–404 BC), often called the Peloponnesian War, was fought between Athens and Sparta and their respective allies for the hegemony of the ancient Greek world. The war remained undecided until the later intervention of the Persian Empire in support of Sparta. Led by Lysander, the Spartan fleet (built with Persian subsidies) finally defeated Athens, which began a period of Spartan hegemony over Greece.

Historians have traditionally divided the war into three phases. The first phase (431–421 BC) was named the Ten Years War, or the Archidamian War, after the Spartan king Archidamus II, who invaded Attica several times with the full Hoplite army of the Peloponnesian League, the alliance network dominated by Sparta (then known as Lacedaemon). The Long Walls of Athens rendered this strategy ineffective, while the superior navy of the Delian League (Athens' alliance) raided the Peloponnesian coast to trigger rebellions within Sparta. The precarious Peace of Nicias was signed in 421 BC and lasted until 413 BC. Several proxy battles took place during this period, notably the battle of Mantinea in 418 BC, won by Sparta against an ad-hoc alliance of Elis, Mantinea (both former Spartan allies), Argos, and Athens. The main event was the Sicilian Expedition, between 415 and 413 BC, during which Athens lost almost all its navy in the attempt to capture Syracuse, an ally of Sparta.

A centaur (/ˈsɛntɔːr, ˈsɛntɑːr/ SEN-tor, SEN-tar; Ancient Greek: κένταυρος, romanized: kéntauros; Latin: centaurus), occasionally hippocentaur, also called Ixionidae (Ancient Greek: Ἰξιονίδαι, romanized: Ixionídai, lit. 'sons of Ixion'), is a creature from Greek mythology with the upper body of a human and the lower body and legs of a horse that was said to live in the mountains of Thessaly. In one version of the myth, the centaurs were named after Centaurus, and, through his brother Lapithes, were kin to the legendary tribe of the Lapiths.

Centaurs are thought of in many Greek myths as being as wild as untamed horses, and were said to have inhabited the region of Magnesia and Mount Pelion in Thessaly, the Foloi oak forest in Elis, and the Malean peninsula in southern Laconia. Centaurs are subsequently featured in Roman mythology, and were familiar figures in the medieval bestiary. They remain a staple of modern fantastic literature.

Description of Greece (Ancient Greek: Ἑλλάδος Περιήγησις, romanized: Helládos Periḗgēsis) is the only surviving work by the ancient "geographer" or tourist Pausanias (c. 110 – c. 180).

Pausanias' Description of Greece comprises ten books, each of them dedicated to some part of mainland Greece. He is essentially describing his own travels, and large parts of Greece are not covered, including the islands. His tour begins in Attica (Ἀττικά) and continues with Athens, including its suburbs or demes. Then the work goes with Corinthia (Κορινθιακά), Laconia (Λακωνικά), Messenia (Μεσσηνιακά), Elis (Ἠλιακά), Achaea (Ἀχαϊκά), Arcadia (Ἀρκαδικά), Boeotia (Βοιωτικά), Phocis (Φωκικά), and Ozolian Locris (Λοκρῶν Ὀζόλων).

Messenia (Ancient Greek: Μεσσηνία) was an ancient district of the southwestern Peloponnese, more or less overlapping the modern Messenia region of Greece. It occupied the peninsular region usually called by the same name along with some of the mainland. To the north it had a border with Elis along the Neda river. From there the border with Arcadia ran along the tops of Mount Elaeum and Mount Nomia and then through foothills of Taygetus. The eastern border with Laconia went along the Taygetus ridge up to the Koskaraka river, and then along that river to the sea, near the city of Abia. The Ionian Sea forms the peninsula's western border, and the peninsula and mainland sections enclose the Messenian Gulf to the south.

Ancient Messenia existed continuously without change of name and with little change of territory to the modern Regional Unit of Greece of the same name.

Doric or Dorian (Ancient Greek: Δωρισμός, romanized: Dōrismós), also known as West Greek, was a group of Ancient Greek dialects; its varieties are divided into the Doric proper and Northwest Doric subgroups. Doric was spoken in a vast area, including northern Greece (Acarnania, Aetolia, Epirus, western and eastern Locris, Phocis, Doris, and possibly Lower Macedonia and Upper Macedonia), most of the Peloponnese (Achaea, Elis, Messenia, Laconia, Argolid, Aegina, Corinthia, and Megara), the Southern Aegean (Kythira, Milos, Thera, Crete, Karpathos, and Rhodes), as well as the colonies of some of those regions in Cyrene, Magna Graecia, the Black Sea, the Ionian Sea and the Adriatic Sea. It was also spoken in the Greek sanctuaries of Dodona, Delphi, and Olympia, as well as at the four Panhellenic festivals; the Isthmian, Nemean, Pythian, and Olympic Games.

By Hellenistic times, under the Achaean League, an Achaean Doric koine appeared, exhibiting many peculiarities common to all Doric dialects, which delayed the spread of the Attic-based Koine Greek to the Peloponnese until the 2nd century BC. The only living descendant of Doric is the Tsakonian language which is still spoken in Greece today; though critically endangered, with only a few hundred – mostly elderly – fluent speakers left.

The Olympic Truce is a tradition originating from ancient Greece that dates back to 776 BC. A "truce" (from Ancient Greek ἐκεχειρία (ékécheiria) 'laying down of arms') was announced before and during the Olympic Games to ensure the host city state (Elis) was not attacked and athletes and spectators could travel safely to the Games and peacefully return to their respective countries.

In 1992, the International Olympic Committee (IOC) renewed this tradition by calling upon all nations to observe the Truce during the modern Games. The Truce was revived by United Nations Resolution 48/11 of 25 October 1993, as well by the United Nations Millennium Declaration relating to the world peace and security. Every two years since the 1993 resolution, the United Nations has adopted, with varying levels of consensus, a resolution reaffirming the ideals of the Olympic Truce.

Elis, also known as Ellis or Ilia (Greek: Ηλεία, Eleia), is a historic region in the western part of the Peloponnese peninsula of Greece. It is administered as a regional unit of the modern region of Western Greece. Its capital is Pyrgos. Until 2011 it was Elis Prefecture, covering the same territory.

The modern regional unit is nearly coterminous with the ancient Elis of the classical period. Here lie the ancient ruins of cities of Elis, Epitalion and Olympia, known for the ancient Olympic Games which started in 776 BC.
