Ancient Thesprotia
Thesprotia was part of the proto-Greek region in the late Bronze Age in which Greek archaic toponyms are densely found.
In antiquity, the territory of modern Thesprotia was inhabited by the ancient Greek tribe of Thesprotians and was bordered by the neighboring regions of Molossia to the north and Chaonia to the east. Thesprotia is mentioned at the Epic Cycle as a place where Odysseus sailed and married the local queen Callidice. Thesprotia became part of the Epirote League before it was annexed by Rome where it became part of the Roman province of Epirus. After the fragmentation of the Roman Empire into East and West, it was part of the Eastern Roman (Byzantine) Empire until the late Middle Ages, except for a period of Bulgarian rule in the 9th-11th centuries. In c. 1430 it fell to the Ottomans.
From the 8th-9th until the 15th century, the region was called Vagenetia, a name deriving from the Slavic tribe of the Baiounitai, who appear in the early 7th century during the Slavic invasions of the Balkans. In the late Ottoman period, the area was known as Chameria, and at 1910 most of the territory of the modern prefecture of Thesprotia was known as Sancak of Resadiye or Çamlık Sancak or Igoumenitsa Sancak.
Thesprotia remained under Ottoman rule until 1913, when it was ceded to Greece after the Ottoman defeat in the First Balkan War. As part of Greece the province of Margariti became part of Preveza prefecture and the provinces of Paramythia and Filiates were part of Ioannina prefecture. The area above river Acheron continued to be referred to as Tsamouria in official Greek government communication until 1937, when the separate prefecture of Thesprotia was established. In 1923, the population of Thesprotia was 60,705, In 1920, there were 20,319 Muslim Albanians in Thesprotia.
