The G7 is a creature of the mid-seventies. It was an attempt by the seven major economic powers to address new international dynamics. It survived its original scope, transformed according to the context and is still operating today. This research wishes to use the G7 as a prism to provide a better understanding of Western diplomatic dynamics in relation to the major phenomena of those years: How did globalisation, the Cold War and an emerging global South impact on transatlantic relations.
