"According to the Ottoman administrative system of the 1880s, Albanians claimed Toskalık or Toskland as encompassing the sancaks of Ergiri, Preveze, Berat and Yanya in the province of Yanya and the sancaks of Görice, Manastir, and Elbasan in the province of Manastir. Toskalık also divided into three parts, Toskalık, Laplık and Çamlık... Chamland (Çamlık) encompassed Margalic, Aydonat, and Filat."

"During the beginning of the 20th Century, the northwestern part of the Greek region of Epirus was mostly populated by an Albanian-speaking population, known under the ethnonyme "Chams" [Çamë, Çam (singular)in Albanian, Τσ(ι)άμηδες, Τσ(ι)άμης in Greek]. The Chams are a distinct ethno-cultural group which consisted of two integral religious groups: Orthodox Christians and Sunni Muslims. This group lived in a geographically wide area, expanding to the north of what is today the Preveza prefecture, the western part of which is known as Fanari [Frar in Albanian], covering the western part of what is today the prefecture of Thesprotia, and including a relatively small part of the region which today constitutes Albanian territory. These Albanian speaking areas were known under the name Chamouria [Çamëri in Albanian, Τσ(ι)αμουριά or Τσ(ι)άμικο in Greek]."
