What ideology had been a driving force behind the success and unity of the Turks in the medieval period

Kemalist ideology

Explanation:

In simple words, Kemalist nationalism promotes the idea that perhaps the Turkish Society is an inseparable whole containing its territories and its citizens, which is described as "the Country unification." It is a notion of patriotism that appreciates the obligation of so many other countries to independence.

Kemalism refers to the ideology of modernisation that led the transformation from the multi-religious, diverse ethnic ottomans to Turkey 's democratic, unitary Republic. Throughout the Turkish revolution Kemalism establishes the limits of the democratic cycle. Atatürk is the father of Kemalism, and also after his demise his philosophy was introduced as State policy.
