The civilian and military postal routes in the Ottoman State were laid out in three main routes. Taking Istanbul as the starting point, the routes were laid out in the form of right, central and left routes in Anatolia and Rumelia. They are connected to each other by secondary roads.
These routes:
In Anatolia (Asian Turkey):
Right route: Through the Üsküdar-Gebze-Eskişehir-Aksehir-Konya-Adana- Antakya route to Aleppo and Damascus later to Al-Hejaz
Central route: Üsküdar-Gebze-Iznik-Bolu-Tosya-Merzifon-Tokat-Sivas-Hasan Çelebi-Malatya-Harput-Diyarbakır-Nusaybin-Kirkuk-Baghdad-Basra
Left route: The same way as Merzifona by the middle arm Ladik -Niksar-Şebinkarahisar-Kelkit-Aşkale-Erzurum -Kars -Tabriz
In Rumelia (European Turkey):
Right route: İstanbul-Vize-Kırklareli-Prevadi-Karasu-Babadagi-İsakçı-Akkirman-Özu-Crimea
Central route: Istanbul-silivri-Edirne-Plovdiv-Sofia-Nis-Yagodina-Belgrade
Left route: Istanbul-Tekirdag-Malkara-Komotini-Kavala-Thessaloniki-Larissa-Tebai-Drac
Apart from these three main roads, there were also Hendek-Gemlik-Mudanya-Ulubat-Susurluk-Ayazment-Bergama-Manisa-Urla-Çeşme-İzmir roads in Western Anatolia.
On these roads, accommodations were made for the postal "tatars" to change horses, for meals and rest and to provide security. These places were first called "Derbend" and later replaced by "Menziller".
