Coalition building is a research area that explores the process of forming alliances or partnerships between individuals, groups, organizations, or countries to achieve common goals or objectives. This process involves identifying shared interests, negotiating differences, establishing trust, and working together towards a common purpose. Coalition building is often seen as a strategy for increasing collective power and influence, as well as for addressing complex issues or challenges that require collaboration across different sectors or communities. Researchers in this area may study various aspects of coalition building, such as the factors that contribute to successful partnerships, the impact of coalitions on policy-making or social change, and the dynamics of collaboration within diverse groups.
