Preambles manifest the self-identity of the constituent assembly, as well as the history and heritage of the nation and its people. This chapter examines references to historical legacy and future-oriented self-identification, constituent power, the sovereignty of the people, the preservation of national, ethnic and cultural heritage, transcendental or religious invocations, constitutional rights, values and principles, and state visions, ideals and societal commitments regarding political and economic cooperation and cultural affinity. Finally, the chapter underlines the legal relevance of preambles as interpretative instruments applied by leading constitutional and supreme courts. Preambles therefore serve as both symbolic declarations and meaningful guides to constitutional interpretation and national self-understanding.
