Conflicts concerning participation, diversity and involvement involve tradition forming as an important strategy for gaining discursive legitimacy. Cultural heritage - in German "Kulturerbe" - refers to the construction of traditions to determine membership in various groups. Parts of this "heritage production" are officially supported by national and global political organizations and thus directly linked to citizenship, often as a legally codified status configuration. Other forms of cultural heritage are developed as civic practice in relation to subject positions that seek to position themselves in the conflict field of social identity assertions. In this research cluster, material and immaterial cultural heritage will be researched in an interdisciplinary manner from a critical and deconstructive perspective.
