  ### Prefecture
  
  Preveza was established as a prefecture in 1915 (Greek: Νομός Πρέβεζας). As a part of the 2011 Kallikratis government reform, the regional unit Preveza was created out of the former prefecture Preveza. The prefecture had the same territory as the present regional unit. At the same time, the municipalities were reorganised, according to the table below.

  ## History
  
  The area was first settled by the Greek tribe of the Thesprotians and subsequently formed part of the Kingdom of Epirus and later the Roman Empire. The Battle of Actium took place in the area in 31 BC, following which the city of Nicopolis ("city of victory") was built by Augustus. The area became part of the Byzantine Empire, and following the Fourth Crusade, split off along with the rest of Epirus to form the Despotate of Epirus. The area passed to Ottoman rule in the 14th century, which lasted until 1913. Following the Balkan Wars, the area was awarded to Greece in 1913, at which point the prefecture was created. The prefecture included the island of Lefkada, until the latter was split off in 1955 as a separate prefecture Lefkada.
