What is a pluralism?

Pluralism is a system of government that dictates that power is shared and distributed between a diverse range of groups rather than concentrated in the hands of an elite. It can therefore be considered the opposite of elitism. Pluralism advocates that pressure groups play a role in setting debate and informing policy. Pressure groups include NGOs such as Amnesty International who campaign on human rights issues or interest groups who represent the interests of their members these can be trade unions such as the National Union of Teachers or associations such as the British Medical Association which represents the views of doctors.
Remember that pluralism derives from the world plural meaning multiple!
