A non-governmental organization NGO is a legally constituted organization created by private organizations or people with no participation or representation of any government. In the cases in which NGOs are funded totally or partially by governments, the NGO maintains its non-governmental status insofar as it excludes government representatives from membership in the organization.
The number of internationally operating NGOs is estimated at 40,000. National numbers are even higher: Russia has 277,000 NGOs. India is estimated to have between 1 million and 2 million NGOs.

Foundations and charities use sophisticated public relations campaigns to raise funds and employ standard lobbying techniques with governments. Interest groups may be of political importance because of their ability to influence social and political outcomes. At times NGOs seek to mobilize public support such as the by the NGO Global Warming Alliance.
