Re-visiting the "territorial trap, " the introduction reviews approaches that have substantially addressed Agnew's critique, such as in transnational scholarship, governance research, border studies, and critical study of statehood. With its past and present complexities, the Caucasus provides ample empirical opportunity to study processes of de-and re-territorialization. Yet, beyond state-centrist and classical grand geopolitical frames little attention has been paid to political space in the Caucasus. The introduction provides a literature review on prevalent approaches to political space in the Caucasus on space-, power-, and process-sensitive empirical research and suggests new research avenues. The article places the contributions to this special issue within theoretical context and assesses their contributions to the debate on political space in the Caucasus.
