Most scholars conclude that Arab anti-Semitism in the modern world arose in the late 19th to early 20th century, particularly around the time of World War I and the subsequent establishment of the British Mandate in Palestine. This period saw the rise of nationalist movements and increased tensions between Arab and Jewish communities, influenced by European anti-Semitic ideologies. The conflict over land and political rights further exacerbated these sentiments, leading to a more pronounced and systemic form of anti-Semitism in the Arab world.
