While scholars have made many claims about US military interventions, they have not come to a consensus on main trends and consequences. This article introduces a new, comprehensive dataset of all US military interventions since the country’s founding, alongside over 200 variables that allow scholars to evaluate theoretical propositions on drivers and outcomes of intervention. It compares the new Military Intervention Project (MIP) dataset to the current leading dataset, the Militarized Interstate Disputes (MID). In sum, MIP doubles the universe of cases, integrates a range of military intervention definitions and sources, expands the timeline of analysis, and offers more transparency of sourcing through historically-documented case narratives of every US military intervention included in the dataset. According to MIP, the US has undertaken almost 400 military interventions since 1776, with half of these operations undertaken between 1950 and 2019. Over 25% of them have occurred in the post-Cold War period.
