Relations between the Slavs and Greeks were probably peaceful apart from intermittent uprisings. There was also a continuity of the Peloponnesian Greek population. This is especially true in Mani and Tsakonia, where Slavic incursions were minimal, or non-existent. Being agriculturalists, the Slavs probably traded with the Greeks, who remained in the towns, while Greek villages continued to exist in the interior, governing themselves, possibly paying tribute to the Slavs. The first attempt by the Byzantine imperial government to re-assert its control over the independent Slavic tribes of the Peloponnese occurred in 783, with the logothete Staurakios' overland campaign from Constantinople into Greece and the Peloponnese, which according to Theophanes the Confessor made many prisoners and forced the Slavs to pay tribute.
