The first traces of settlement in Patras date to as early as the third millennium BC, in the area of modern Aroi. Patras flourished for the first time in the Post-Helladic or Mycenean period (1580–1100 BC). Ancient Patras was formed by the unification of three Mycenaean villages in modern Aroi, namely ancient Aroe, Antheia (from mythological Antheia) and Mesatis. Mythology has it that after the Dorian invasion, a group of Achaeans from Laconia led by the eponymous Patreus established a colony. In antiquity Patras remained a farming city. It was in Roman times that it became an important port.
After 280 BC and prior to the Roman occupation of Greece, Patras played a significant role in the foundation of the second "Achaean League" (Achaiki Sympoliteia), along with the cities of Dyme, Tritaea and Pharai. Later on, and following the Roman occupation of Greece in 146 BC, Patras played a key role, and Augustus refounded the city as a Roman colony in the area. In addition, Patras has been a Christian centre since the early days of Christianity, and, in both the East Orthodox and Roman Catholic traditions, it is the city where Saint Andrew was crucified.
n the Byzantine era, Patras continued to be an important port as well as an industrial centre.[citation needed] One of the most scholarly philosophers and theologians of the time, Arethas of Caesarea was born at Patrae, at around 860. By the 9th century, there are strong signs the city was prosperous: the widow Danielis from Patras had accumulated immense wealth in land ownership,[citation needed] the carpet and textile industry, and offered critical support in the ascent of Basil I the Macedonian to the Byzantine throne.
In 1205, the city was captured by William of Champlitte and Villehardouin, and became a part of the principality of Achaea. It became the seat of the Barony of Patras, and its Latin archbishop primate of the principality. In 1408, Patras became Venetian, until it was recaptured in 1430 by the Despotate of Morea and its despot Constantine Palaiologos, who thus succeeded in recovering for the Byzantine Empire the whole of the Morea, apart from Venetian possessions. The administration of Patras was given to George Sphrantzes, while Constantine was immediately contested by the Ottoman Empire and later, in 1449, became emperor of the Byzantine empire.
Patras remained a part of the Despotate of Morea until 1458, when it was conquered by the Sultan of the Ottoman Empire, Mehmet II. Under the Ottomans, it was known as "Baliabadra", from the Greek: Παλαιά Πάτρα ('Old Patras'), as opposed to Νέα Πάτρα ('new Patra'), the town of Ypati in Central Greece. Though Mehmet granted the city special privileges and tax reductions, it never became a major centre of commerce. Venice and Genoa attacked and captured it several times in the 15th and 16th centuries, but never re-established their rule effectively, except for a period of Venetian rule in 1687–1715 after the Morean War.
In 1772, a naval battle took place off the city between the Russians and Ottomans.
