Founded in antiquity, the city became an important seaport in the Middle Ages during the Frankokratia as part of the lordship of Argos and Nauplia, held initially by the de la Roche following the Fourth Crusade before coming under the Republic of Venice and, lastly, the Ottoman Empire. The city was the second capital of the First Hellenic Republic and of the Kingdom of Greece, from 1827 until 1834.
