The Siege of Patras in 805 or 807 was undertaken by the local Slavic tribes of the Peloponnese, reportedly with aid from an Arab fleet. The siege's failure, attributed to the miraculous intervention of the city's patron, Saint Andrew, marked the consolidation of Byzantine control over the Peloponnese peninsula after two centuries of Slavic rule over its western half. It also marked the beginning of the ascendancy of the Metropolis of Patras in the peninsula's ecclesiastical affairs.

The Byzantine Empire's military position in the Balkans collapsed in the early 7th century as a result of disastrous military ventures against the Persians and then the Arabs in the East, which forced the effective abandonment of the Danube limes and opened the way for large-scale penetration and settlement of the Balkan hinterland by various Slavic tribes. The Slavs raided as far as southern Greece and the coasts of Asia Minor. Most of the region's cities were sacked or abandoned and only a few, including Thessalonica, remained occupied and in imperial hands.

In Greece, the eastern coasts of the Peloponnese and Central Greece remained in Byzantine hands as the theme of Hellas, while in the interior, various Slavic groups established themselves. A large native Greek population probably also remained in the land, either mixed with the Slavs or in its own autonomous communities. As elsewhere, a mostly peaceful modus vivendi soon emerged between the Slavs and the remaining Byzantine strongholds, with the mainly agricultural Slavs trading with the Byzantine-held coastal towns. Further north, in the Greek mainland, by the turn of the 7th to 8th century smaller Slavic districts or sclaviniae emerged around the fringes of imperial territory, ruled by their own archons, who received Byzantine titles and recognized some form of imperial suzerainty. Imperial authority across Greece was greatly strengthened by the 783 campaign of the logothete Staurakios, who ventured from Constantinople overland to Thessalonica and from there south to the Peloponnese, subduing the Slavs of those regions.
