The Holocaust has left a deep scar in the history of the Jewish people, representing a dark period that resulted in the loss of millions of lives. After this traumatic period, the surviving Jewish diaspora found themselves confronted with the challenge of rebuilding their religious identities and beliefs alongside their survival. This paper is written with the aim of understanding and evaluating the religious and religious changes that occurred in the Jewish diaspora after the Holocaust. This study focuses on the religious and religious changes that took place in the Jewish diaspora after the Holocaust. The research encompasses efforts to preserve religious identities, adapt religious practices, cope with the influence of the modern world, and understand the emergence of new religious movements. In the aftermath of the Holocaust, Jewish communities faced a significant religious crisis. The devastation caused by the genocide, the loss of religious leaders, and the dispersal of communities created significant challenges in preserving religious identities and maintaining religious life. This study holds great importance in understanding the reasons and consequences of religious changes in the post-Holocaust period and evaluating the measures taken to strengthen the religious identities of Jewish communities. This research aims to examine in detail the religious and religious changes that occurred in the post-Holocaust Jewish diaspora. By addressing fundamental issues such as changes in religious practices within and outside communities, the balancing of religious values with the modern world, the reconstruction of religious identities, and the emergence of new religious movements, this study aims to comprehend and evaluate this process. The study is designed as a qualitative research. Historical documents, academic articles, research reports, and other reliable sources will be used to conduct a literature review of religious changes in the post-Holocaust Jewish diaspora. In the post-Holocaust period, religious and religious changes occurred in the Jewish diaspora. Communities engaged in efforts to preserve and reconstruct their religious identities, resulting in variations in religious practices both within and outside these communities. The influence of the modern world necessitated a balance of religious values, and the emergence of new religious movements was observed in some communities. This study provides an important perspective for understanding the reasons, consequences, and reactions of communities to religious changes in the post-Holocaust period. This perspective could contribute to future religious changes and the efforts of communities to preserve and strengthen their religious identities.bDuring the post-Holocaust period, communities undertook efforts to preserve and reconstruct their religious identities, leading to variations in religious practices due to migration to different countries. The influence of the modern world made it crucial to balance religious values, and innovative methods were developed for religious education and learning. Additionally, the emergence of new religious movements was notable in certain communities. These findings underscore the complexity and significance of religious changes in the post-Holocaust period. In conclusion, the religious and religious changes in the post-Holocaust Jewish diaspora are a significant research topic from historical and sociological perspectives. This study has been conducted to understand the steps taken by Jewish communities to preserve and strengthen their religious identities and provide important insights for the future. Understanding this process could support the efforts of communities to strengthen their religious identities and pass on religious values to future generations.
