Coalition governments are observed frequently in parliamentary systems. Approximately 70% of all governments in postwar Europe have been one type of coalition or another. Israel has never been ruled by a single-party government in its history. Recently, majoritarian systems like Britain produced coalitions, taking many by surprise.
The prominence of coalitions in parliamentary democracies compels researchers to study them more closely. The Comparative Politics literature investigates, in particular, the dynamics of coalition formation and termination, as well as the domestic policy outputs of coalitions, especially compared to governments ruled by a single party.
Coalitions have generated interest on the International Relations front as well. One avenue of research transcends the “political party” as a building block and conceptualizes coalitions as a “decision unit” by focusing on the group of veto players in a regime’s foreign policy apparatus. Another line of scholarship, situated in the “Democratic Peace” framework, looks at coalitions as a domestic-institutional factor to observe their effects on the likelihood of international conflict.
Departing from the “Democratic Peace” tradition, more recent research in Foreign Policy Analysis rejuvenates the study of coalitions in international politics. This literature not only encourages theory development by scrutinizing why coalitions behave differently than single-parties in the international arena but also bridges the gap between International Relations and Comparative Politics. Emphasizing the organic relationship between domestic politics and foreign policy, foreign policy researchers dissect coalition governments to highlight the role political parties play on foreign policy formulation and implementation. This literature also illustrates the merits of methodological plurality in studying foreign policy. Using a combination of comparative case studies, process tracing, Qualitative Comparative Analysis (QCA) and regression modeling, it sheds light not only on the broader trends that characterize coalition foreign policy but also on the causal mechanisms and contextual factors which often go unaccounted for in purely statistical analyses. The recent advances in role and image theories in Foreign Policy Analysis are expected to influence the study of coalitions and their foreign policies, offering an interpretivist take alongside this positivist trajectory.

National secession seeks to create a new sovereign state for a nation residing on its homeland that is currently located inside another sovereign state. This goal distinguishes national secession from regional secession, autonomy, and decolonization and shapes the strategies, operational objectives, and tactical choices of the leaders of national-secession campaigns. Explanations for the success of some campaigns—particularly, success at getting on the global agenda—have focused on the identities, grievances, or greed of their members. Explanations for why some campaigns have turned to protracted intense violence have focused on these motivations and on tactical-logistical opportunities.
The existing literature suffers from its failure to agree on theoretical and conceptual fundamentals. As a consequence, empirical studies focus on very different universes of cases and operationalize key variables in diverging ways. The existing literature frequently does not consider how the goal of national secession constrains the strategies, operations, and tactics of such campaigns. And so, it often fails to consider whether studies with another dependent variable can be extended to the study of national secession. Explanations stress indeterminate or substitutable causes and remote constraints on most national-secession campaigns—causes and constraints taken “off the shelf” from theories about conflicts operating under very different strategic and operational constraints. Missing from these explanations is the authenticity and realism of the programs for national secession in the assessments of the populations that each program presents as a nation with a right to a sovereign state of its own. Explanations and recommendations for responses by common-state governments, their allies, and the international community often fail to understand the centrality of the war of programs between national secessionists and common-state governments and the ways this constrains what compromises are possible and what responses are most likely to lead to domestic and international peace in such conflicts.
