Explanation: Euboea is recognized as the second-largest island in Greece by both land area and population, surpassed only by Crete.

Explanation: Euboea is situated off the coast of mainland Greece, separated from Boeotia by the narrow Euripus Strait, which measures approximately 40 meters (130 feet) at its narrowest point.

Explanation: Euboea possesses an elongated, narrow morphology, extending approximately 180 kilometers (110 miles) in length. Its width fluctuates significantly, from roughly 50 kilometers (31 miles) to as little as 6 kilometers (3.7 miles).

Explanation: Geological evidence suggests Euboea was once contiguous with the mainland, subsequently becoming an island due to seismic activity, a theory supported by its proximity to fault lines and historical seismic events.

Explanation: Euboea is characterized by a substantial mountain range extending along its length, featuring prominent peaks such as Dirfi, Kantili, and Pyxaria in the northeast, and Ochi in the southern sector.

Explanation: Mount Dirfi represents the highest elevation on Euboea, attaining an altitude of 1,743 meters (5,719 feet).

Explanation: The predominant climate across Euboea is Mediterranean, classified as Csa under the Köppen system, marked by hot, arid summers and temperate, moist winters.

Explanation: Euboea's climate conforms to the Csa classification within the Köppen system, indicative of a Mediterranean climate featuring hot, dry summers.

Explanation: Euboea is served by two principal national roads: Greek National Road 44, traversing the central, southern, and southeastern regions, and Greek National Road 77, which extends through the northwestern, northern, and western sectors.

Explanation: Contemporary Euboea is linked to the Greek mainland via two suspension bridges. One bridge is situated in Chalcis, offering access from Thebes, while the second bridge bypasses Chalcis, providing access from Athens.

Explanation: The Euripus Strait is noted for its pronounced tidal fluctuations, characterized by rapid shifts in current direction and velocity, a phenomenon recognized since antiquity and historically perceived as hazardous by mariners.

Explanation: Euboea possesses a total land area of 3,684 square kilometers, equivalent to 1,422 square miles.

Explanation: Historically, Euboea was designated by several ancient names, such as Macris and Doliche, referencing its elongated form. Other appellations included Ellopia, Aonia, and Abantis, derived from indigenous tribes.

Explanation: The nomenclature 'Euboea' derives from the Ancient Greek terms 'eu' (good) and 'boos' (ox), translating to 'the land of the well-fed oxen'.

Explanation: Throughout the Middle Ages, Euboea was frequently referred to as Chalcis or Euripos by Byzantine scholars. The designation Negroponte, signifying 'Black Bridge,' arose from Italian folk etymology associated with the Chalcis bridge, gaining prominence during Venetian governance.

Explanation: The appellation Negroponte is hypothesized to have originated from a rebracketing of the Greek phrase 'steno Evripon' (meaning 'to Evripos') into 'sto Nevripon,' with the Italian term 'ponte' (bridge) subsequently linked to the Chalcis bridge.

Explanation: During Ottoman administration, the island and its principal city were designated as Eğriboz or Ağriboz, a nomenclature also derived from the Euripus Strait.

Explanation: The contemporary orthography of the island's name is Evia.

Explanation: The historical narrative of ancient Euboea is significantly shaped by its principal cities, Chalcis and Eretria. These Ionian Greek settlements played a pivotal role in founding numerous colonies across Magna Graecia and Sicily, thereby expanding Hellenic influence and establishing crucial trade arteries.

Explanation: The Euboic system of weights and measures exerted considerable influence in antiquity, adopted by numerous Ionic city-states and utilized in Athens until the late 7th century BC, underscoring the economic significance of Euboea's urban centers.

Explanation: The classicist Barry B. Powell posits that Euboea may have served as the locus for the initial adoption of the Greek alphabet, circa 775-750 BC. Furthermore, scholarly speculation suggests the epic poet Homer may have resided on the island for a period.

Explanation: The Lelantine War constituted a significant early conflict in Hellenic history, contested between the rival Euboean cities of Chalcis and Eretria, and involving a multitude of other Greek city-states.

Explanation: In 490 BC, Eretria suffered destruction at the hands of Persian forces due to its participation in the Ionian Revolt. Despite subsequent re-establishment near its original location following the Battle of Marathon, the city never regained its prior prominence.

Explanation: Athens deemed Euboea strategically indispensable for securing resources such as grain and cattle, and for defensive considerations. Athenian actions included the invasion of Chalcis in 506 BC, the settlement of Attic Greeks on its territory, and the suppression of a revolt in 446 BC, solidifying the island's status as an Athenian dependency.

Explanation: Post the Battle of Chaeronea in 338 BC, Euboea fell under the dominion of Philip II of Macedon, and subsequently, during the second century BC, it was integrated into the Roman Republic.

Explanation: The Euboean League functioned as the governing body for the island, spanning from the early Hellenistic era through the Roman Imperial period, signifying a structured political and economic framework for Euboea's constituent cities.

Explanation: The esteemed philosopher Aristotle died on Euboea in 322 BC, having taken up residence at his family estate in Chalcis subsequent to his departure from Athens.

Explanation: Euboea achieved the restoration of its independence from Athenian control by 410 BC, amidst the context of the Peloponnesian War.

Explanation: Owing to its relative isolation, Euboea experienced minimal devastation from barbarian incursions prevalent in late antiquity and the early medieval period, thereby preserving a degree of prosperity, as indicated by archaeological findings from the 7th century.

Explanation: Following the Fourth Crusade, Euboea rose to prominence upon its occupation by Lombard families, who partitioned it into three baronies, establishing the Triarchy of Negroponte. Subsequently, Venetian influence expanded, culminating in Venetian sovereignty and control over the island's commerce.

Explanation: The Ottoman Empire, under the command of Sultan Mehmed II, subjugated Euboea from Venetian control on July 12, 1470, concluding a protracted and arduous siege of its capital, Negroponte (Chalcis).

Explanation: On July 12, 1470, the heavily fortified city of Negroponte (Chalcis) was captured by the Ottoman Empire, under Sultan Mehmed II, from the Republic of Venice, concluding a prolonged and intense siege.

Explanation: Albanian migration to Euboea commenced circa 1402, facilitated by Venetian encouragement. Notable waves of settlement occurred in 1425 and 1435, with these Albanian populations eventually integrating with the island's established Greek populace.

Explanation: Subsequent to the conclusion of the Greek War of Independence in 1830, Euboea was formally incorporated into the newly constituted independent Kingdom of Greece.

Explanation: Euboea's economy is bolstered by mining activities, including magnesite extraction in Mantoudi and Limni, lignite exploitation in Aliveri, and iron and nickel extraction from the Dirfys region. Marble quarrying occurs near Eretria, and asbestos mining is conducted in the northeastern sector of Carystus.

Explanation: Johann Georg Von Hahn's 1854 report indicated that southern Euboea, excluding Karystos, was predominantly Albanian, with an estimated 25,000 Albanian inhabitants out of a total island population of 72,368.

Explanation: The village of Antia, situated in southern Euboea, is distinguished by its unique whistled language, known as sfyria. This linguistic practice involves a whistled rendition of spoken Greek, employing specific tones and frequencies to convey letters and syllables.

Explanation: In 2021, northern Euboea experienced a catastrophic forest fire that persisted for a week, resulting in the destruction of over 50,000 hectares of forest and agricultural land, classifying it among the most extensive fires in recent Greek history.

Explanation: Euboea is home to Arvanite communities, predominantly situated in the southern areas, where monolingual Arvanitika speakers resided in roughly 60 villages until the 1970s. Furthermore, Sarakatsani and Vlach populations are present in the mountainous central and northern regions, though their nomadic traditions have largely diminished.
