The center of this research is the Christological aspects in the poetry of one of the greatest and most significant Croatian poets, Silvio Strahimir Kranjčević. He is presented as a poet who is between Croatian traditional poetry and modernist movements. This modernism in him is best shown through his rebelliousness and unrest that pervade his three periods of creativity. The paper presents the development of Kranjčević's Christology through three periods of his creativity, i.e. through his only three collections that were published during his lifetime. His mental and religious crises, various doubts and numerous questions to which he is trying to find answers can be seen through his poetry. He often seeks the answer in the life of Jesus Christ, and thus his Christology "strikes" clear foundations from the beginning and develops through his faith. The central event of Christ's life – his sacrifice for people, is precisely the central event, the central theme of his Christology. The chapter on Christological aspects in literature showed more clearly what exactly is required under these aspects and how to recognize these aspects. The central part of the work consists of the analysis of songs that offer clear Christological aspects, and through which we can observe the very development of Kranjčević's Christology through the three periods of his creativity. At the end, a conclusion is reached with the final picture of Kranjčević's Christology connected with his views and reflections.
