Archaeological excations he proved that Zakynthos was inhabited from the Neolithic Age. The island is first mentioned by the Greek poet and writer Homer. In his masterpieces, the Iliad and the Odyssey, he stated that the first inhabitants of Zakynthos were the son of King Dardanos, Zakynthos (which the island has been named after), of Troy and his men who settled around 1500-1600 BCE.
Over the years the island was conquered by King Arkeisios of Kefalonia, and after him Ulysses from Ithaca. Later on Zakynthos became the first independent democracy in the Hellenic area, as a treaty was signed and it lasted over 650 years.
In the summer of 1953, Zakynthos was hit by two severe earthquakes, resulting in the total destruction of the islands infrastructure and most of its state archives. The most powerful of those quakes registered 7.3 on the Richter scale occurred on 12 August and was felt throughout almost the entire country. In Zakynthos Town only three buildings were left standing: the St. Dionysios Cathedral, the National Bank building, and the church of St. Nicholas "tou Molou". The rebuilding of the island was subject to a very rigid anti-seismic code, and has thus withstood several moderate and powerful earthquakes with a minimal amount of damage, including one in 2005.
Mining has been common on the island. Today, however, the only activity is two quarries on the mountain range in the western part of the island. A small mountain on Zakynthos west side was mined during the late 20th-century, though it is no longer in use. Today tourism is the most important source of income and Zakynthos is one of the most popular tourist destinations in Greece.
