This curriculum unit teaches students about nationalism within the context of Europe and is designed to help better understand the history of Yugoslavia and why Yugoslavia fell apart. The unit focuses on Yugoslavia as a multinational state and how the federation was organized during different historical time periods. There are three lessons in the unit. Lesson 1, "Europe, Yugoslavia, and Nationalism: An Introduction," introduces students to the geography of Europe and Yugoslavia and how nationalism was influenced by geographic factors. Lesson 2, "The Road to Sarajevo," uses a readers' theater to introduce students to events spanning a period from 1876 to 1918 and focuses on the assassination of the heir to the throne of the Austrian monarchy and the motivations behind the killing. Lesson 3, "The One and the Many: Unity and Diversity in a Multinational State," provides the opportunity to examine Yugoslavia and its various nationalities, exploring how this multinational state worked, or didn't, and what divided or united the various nationalities and republics during different times. Appendixes include a timeline, notes, and a list of 27 general resources and 29 suggested readings. (EH)
