Since World War Two the world has undergone a profound economic and political transformation, from an international economy and internationalist politics to a global economy and globalist politics. The Bretton Woods international financial institutions have 'structurally adjusted' Third World countries, and similar structural reforms have occurred in First World countries. The environmental consequences of globalising economic activity have been severe and also global; the social consequences of the structural reform process are equally severe. National sovereignty has been radically compromised by globalisation, and previous nationally-based initiatives to manage the activities of capital in order to mitigate its negative impacts on society and the environment, such as social democrat/labour politics, have ceded their authority to globalism. Green parties have arisen to contest the negative environmental and social consequences of the global expansion of capital, and are replacing socialist parties as a global antisystemic political force. Green politics had its origins in the world-wide 'new politics' of the New Left and the new social movements of the 1960s, and the world's first two Green parties were formed in Australia and New Zealand in 1972. A general history of the global forces which gave rise to Green politics, and a specific history of the first two Green parties, demonstrate the interplay of global and local political forces and themes, and provide an opportunity to redefine the core elements of Green politics.
