The disintegration of the former Yugoslavia posed challenges for the universal concept of the Yugoslav Muslim nation for which several development paths were imaginable under the new circumstances. The concept of Bosniakdom, which was initially developed to address the Muslims of Bosnia and Herzegovina, gradually grew to become a new and coherent national program to include all the Muslims of former Yugoslavia, primarily due to its new pan-Bosniak orientation. The present article traces the conceptual history of the national ideas of Muslimdom versus Bosniakdom within the former Yugoslav states, as well as the conceptual and institutional history of the pan-Bosniak idea and movement during the 1990s and 2000s. It does this by emphasizing the decisive role the Official Muslim Community in Bosnia and Herzegovina played in their development and divulgence. This article claims that, contrary to some expectations, the strategy of internationalization and universalization of the hitherto territorial concept of Bosniakdom toward Muslims in neighboring countries during the second half of 1990s and 2000s was closely linked to the idea of the construction of the Bosniak national state. It also proposes that the evolution of Bosniakdom into pan-Bosniakdom during that time primarily followed concerns related to that goal.
