Abstract
The paper examines the roots of the national spiritual and cultural values of present Kazakh society in the language of written relics from the era of the Ulus of Jochi. The study of spiritual and cultural encodings using linguistic data shows the relevance of the work. The role and significance of the written heritage of this era for Kazakh spirituality has been comprehensively proven. The aim of the research is to prove, through the language of written monuments, the direct affiliation of the Ulus of Jochi to the consolidation of the Kazakh people into a single center, the unification of the language, the definition of spiritual and cultural values, the development of literature and the growth of potential in political and social terms. The aims and objectives set for the research work were fulfilled in theoretical and practical terms. Idioms, proverbs and sayings, stable phrases in the language of written monuments written in the Middle Turkic era on the territory of the Ulus of Jochi are compared with data from the modern Kazakh language and scientific conclusions are presented. It is undoubtedly that the Kazakh people are the spiritual and cultural heirs of the nomads of the Great Steppe. When comparing the literary and linguistic data of the two eras, heredity becomes even more obvious. Along with this, it is scientifically substantiated that written monuments are the spiritual and cultural heritage of the Kazakh people. National worldview, national traditions, spiritual and cultural codes began to form in our language from ancient times, developed under the Ulus of Jochi and led to the consolidation of our nation today. This is evidenced by an in-depth analysis of the evidence.
