Using an adaptation of Daniel Flemes’ conceptualisation of regional power, this thesis analyses Saudi leadership in the first four and a half years of the Yemen Civil War (March 2015 – August 2019). The case study was performed using an overarching causal-process tracing approach. Three variables that are fundamental for Saudi regional leadership in Yemen have been distinguished; claim to leadership, material methods of self-assertion and acceptance of leadership. As these variables are different in nature, they have been analysed using different methodologies. The findings of these analyses suggest that it is easy to ascribe a regional leading role to Saudi Arabia, as its claim to leadership and growing regional assertiveness are evident, but that real leadership over countries in the region is missing. Ultimately, this thesis illustrates that case study research is essential in the process of classifying a country as ‘regional power’.Show less
