political coalitions

Political coalitions are alliances between parties, factions, or interest groups that join forces to achieve shared objectives.

In parliamentary systems, coalitions often form governments when no single party wins a majority: The coalition government collapsed after the junior partner withdrew.

Coalition also describes broader alignments—labor unions, advocacy groups, and politicians uniting around a cause: a coalition of environmental organizations.

Coalition-building is central to democratic politics, requiring compromise among groups with overlapping but distinct agendas.
