The 19th century is known as a century in which many developments took place in the world. In the relevant century, the characteristic structure of societies changed and the phenomenon of modernity began to come to the fore in every field. Thus, various currents of thought spread and the Empires that included today's nation-states began to collapse. The Ottoman and Austro-Hungarian Empires also experienced the mentioned collapse process. Germany, which became a nation-state during the Franco-Prussian War in 1871, experienced a demographic change that is important for the subject of this study and enabled the training of many Jewish orientalists. In the mentioned historical atmosphere, the birth of Jewish Orientalism emerged when Jews and Jewish orientalists who could not establish an independent state resided in various parts of Europe. The aim of the study is to reveal the regional studies shaped by the visits of Jewish orientalists such as Ignaz Goldziher (1850- 1921), Gustav Weil (1808-1889), Gottlieb Leitner (1840-1899) from the center of Europe to the Middle East in the 19th century under the name of scientific activities, and to examine how they benefited from Islamic sciences in the places they went. The fact that these orientalists had the image of ""Easterns of Europe"" in Europe and their efforts to present Judaism as the repository of Islam paved the way for the establishment of the 20th century State of Israel in an intellectual sense. The study is based on a qualitative, critical analysis in terms of method. This method, which also provides a comparative approach to the subject, is important for the validity of the results obtained in the study. As a matter of fact, this study examines the regional travels and activities of Jewish orientalists in the Middle East and concretely shows their contributions to the founding ideas of the State of Israel, which unfairly positions itself today. Moreover, it reveals the direct or indirect connections of the State of Israel with ""Zionist"" movements. As a result, the study shows that although the intellectual movements originating from the Jewish orientalists that started in the 19th century appear to be a cultural heritage, they have not been well analyzed by the people of the region. These movements have qualities that explain how the State of Israel, which follows a Zionist philosophy, inflicts humanitarian harm on the Muslim geography. Since the ideas of the Jewish orientalists, who influenced the 20th century, have not changed, it is necessary to examine the studies conducted in the East within a critical framework. As a matter of fact, today's world is watching the State of Israel's oppression of Palestinians in the 21st century. Preventing past insensitivity necessitates examining foreign sources in a critical manner. However, it would be inappropriate to carry out analytical studies and only mention the claims of Jewish orientalists about the Islamic religion and the Islamic world, which are of no use to us. The academic inadequacy of those claims and approaches should be expressed on every platform. Moreover, this truth is the duty of the academic world.
