The Ottoman State had to leave some of its territory in the 19th century. The most striking of these was undoubtedly experienced after the defeat known as 93 Harbi. According to this, the Ottoman Empire no longer has the right to sovereignty over some of the territories in Rumelia. One of the sides of these developments was Greece. The territory from the province of the Ottoman Empire known as Yanya and the sanjak of the Tırhala was demanded by Greece. At the Berlin Congress, it was decided that Greece should be given land and that the Ottoman-Greek border should be restructured. At the end of the negotiations made, the Tırhala remain in Greece. In the province of Yanya, the demands of Greece are completely unacceptable. The Narda River was regarded as the border as it remains in Greece. As a result of the new boundaries drawn in this way, the issue of the refugee comes up as every loss of land. The Muslims in the abandoned places begin to migrate to the Ottoman side. The Ottoman authorities want to build a nearby immigrant town so that the people will not suffer from this kind of migration. It is also believed that it would be useful to have a Muslim town in the vicinity of the abandoned Narda a few hours away. The town of Louros, established for this purpose, was transformed into a kaza center by the involvement of villages and farms on the Ottoman side. The Ottoman State thought to prevent the difficulties that could arise in providing the immigrants’ food and settlement after the new border was drawn.

For this reason they built a new town for the immigrants and made this town an administrative center.
