1256-1487 · 231 years
The Karamanid Principality, based at Larende (modern Karaman), was one of the most enduring Anatolian beyliks — surviving 231 years from its 1256 founding to Ottoman conquest in 1487. The principality's territory included the Durayda land that would later become Mesudiye village.
The Karamanids descended from Karaman Bey, a Turkmen chieftain who founded the principality in 1256 in the wake of the Mongol invasion and the decline of the Seljuks of Rum. Their capital was Larende — the modern city of Karaman, just 15.7 km southeast of present-day Mesudiye village.
On 13 May 1277, Karamanoğlu Mehmed Bey issued a famous decree declaring Turkish as the official language of the principality's administration — a milestone in Turkish cultural history. This date is now commemorated annually in Türkiye as Turkish Language Day. The Karamanids thus deserve credit for the first official adoption of Turkish as a state language in Anatolia.
In 1432, Karamanid II. İbrahim Bey allocated the "Oraydonya pasture" (likely connected to the present-day Durayda toponym) as a revenue source for the Larende Imaret endowment. This is the first documented administrative connection between the Karamanid state and the land that would later become Mesudiye village — predating Ottoman tahrir registration (1500) by 68 years.
Mehmed II completed the Ottoman conquest of Karaman in 1467, ending Karamanid political independence. A nominal Karamanid presence persisted in vassalage until 1487, when the Karaman territory was fully absorbed into the Ottoman state. The Durayda land then became part of the Ottoman administrative system, recorded in tahrir registers from 1500 onwards.
