Abstract
The article reveals the path of Islamization and the role of religion, which were necessary for the Qarakhanids to legitimize power within the state and activate foreign policy activities. For these purposes, the motives, causes and consequences of Islamization were studied, and the connection of Islamization with the traditions of foreign relations was established. The purpose of the study is to study the influence of Islamization on the foreign policy activities of the Karakhanids and in what form it was used. The author argues that religious authority and orthodoxy also played a major role in relations between Muslim states, relying on information from Arabic and Persian sources. Attention is also paid to the relations of the Qarakhanids with non-Muslim countries, with which, mainly, trade and economic relations were established, although at first they were not peaceful and often resulted in armed conflicts. The influence and place of religion in the foreign policy of the Qarakhanids is clearly demonstrated in relations with the Ghaznavids, Saljuqs and Song China, which the author cites from sources in Arabic, Persian and foreign studies. The works of Ibn al-Athir, Ibn Taghriberdi, Bayhaqi, al-Karshi, Nizami Aruzi, ar-Ravendi became the main sources in this study. This work shows that the role of religion is much broader and fundamental in the history of medieval states and Islamization was a platform for dialogue.
