In this edited volume we invited authors from different continents to discuss theories of regional powers and regional orders (Part I), the relationships between regional powers and their neighbourhood (Part II) as well as the role of regional powers in the sub-global power distribution (Part III). Inspired by the omnipresence of the alleged rise of new ‘regional powers’ such as Brazil, China, India and South Africa, the individual chapters assembled here have attempted to transcend traditional perspectives on power and the narrow, essentialist dimensions of regions and regional orders. The single chapters have instead inquired as to the prerequisites for region-building from various angles, coalescing geographical with interactionist, institutionalist and interpretive insights, while using illustrations from different world regions to make their various cases.
