There were three main phases of globalization in history:
1) From 1492 to around 1800, which saw exploration and the establishment of colonies as European powers sought to expand their influence and gain resources.
2) From 1800 to 1940, characterized by the expansion of international trade and the growth of multinational companies, though this period ended with the outbreak of World War 1 and 2.
3) From 1950 onwards, led by the establishment of institutions like the IMF, World Bank, and GATT/WTO to promote free trade and economic cooperation in the postwar period and reduce barriers to international commerce.
