 Additionally, the crypto-Jewish conspiracy claim has been used throughout modern Turkish history by rightists and Islamists to undermine the legitimacy of incumbent political leadership, and, today, by leftists and secularists seeking to undermine the political legitimacy of Erdogan and the origins of Islamism more broadly.These, like other claims of Jewish aspirations to world-domination, embodied in part by the successes of Zionism, join the ranks as examples of both the enduring nature of such canards in contemporary Turkey, and of their deep-seated relationship with pervasive, worldwide theories of political conspiracy propagated by radically different political elements often simultaneously.In 1924, Mehmet Karakaş Rüştü, claiming to belong to the Karakaş Dönmehs, made allegations about Dönmehs to the "Vakit" newspaper.
