 Their activity included massacres, looting and destruction in the regions of Epirus, Western Macedonia, Central Greece, Thessaly, Peloponnese suffered most destruction and massacre due to the activity of 15,000 Muslim Albanian mercenaries.In 1779 the Ottoman army finally managed to drive those groups out of Peloponnese, while the remaining ones were either killed by local villagers or found refuge in Muslim Albanian communities in Lala and Vardounia.The period of 1770-1779 is generally termed as "Alvanokratia" (Albanian rule) in Greek historiography.
