A coalition refers to the unification of groups, organizations, or individuals to works towards a shared goal as a team. Coalitions generally fall into two camps: internal or external. Internal coalitions are comprised of individuals who are already part of an organization, such as a workplace, while external coalitions are comprised of members of diverse organizations who join together to combine efforts. Coalitions exist at every level of governance, from local and community-based to international.
Input: individuals who have a shared mission, connect with each other, and want to enact something; a trigger that inspires formation (i.e. an event, a threat, or a piece of controversial legislation)
Output: a partnership of organizations or individuals working together to achieve a goal
Coalitions are traditionally associated with defeating a common enemy. Coalition warfare dates back to ancient Greece, when a coalition of city-states came together to ward off the Persian Empire.
Online toolkits for building a coalition can be found easily, outlining structures, systems of governance, and steps for building; the National Democratic Institute partnered with the Oslo Center for Peace and Human Rights to create a manual entitled Coalitions: A Guide for Political Parties with extensive information on best practices.
