A grassroots movement is one that uses the people in a given district, region or community as the basis for a political or economic movement. Grassroots movements and organizations use collective action from the local level to implement change at the local, regional, national, or international levels. Grassroots movements are associated with bottom-up, rather than top-down decision-making, and are sometimes considered more natural or spontaneous than more traditional power structures.Grassroots movements, using self-organization, encourage community members to contribute by taking responsibility and action for their community. Grassroots movements utilize a variety of strategies from fundraising and registering voters, to simply encouraging political conversation. Goals of specific movements vary and change, but the movements are consistent in their focus on increasing mass participation in politics. These political movements may begin as small and at the local level, but grassroots politics as Cornel West contends are necessary in shaping progressive politics as they bring public attention to regional political concerns.The idea of grassroots is often conflated with participatory democracy. The Port Huron Statement, a manifesto seeking a more democratic society, says that to create a more equitable society, "the grass roots of American Society" need to be the basis of civil rights and economic reform movements. The terms can be distinguished in that grassroots often refers to a specific movement or organization, whereas participatory democracy refers to the larger system of governance. Source: Wikipedia (en)
