This thesis examines the impact of democracy on alliance abrogation. It serves as an extension of the current literature that examines democratic commitments and merges that with alliance studies. The data used consists of alliances from 1816-1991 and has been composed using EUGene from Leeds and Anac (2005), Correlates of War, and Polity IV. Using a standard probit model, this thesis examines the relationship between democracy and alliance commitments in a systematic approach and finds little evidence to support existing theoretical justifications on how democracies behave in an alliance
