Final answer:
The claim that modern globalization began around post WWI is false. The first wave of globalization started in the 19th century but was disrupted by WWI. Modern globalization regained importance after the disruptions of the two World Wars and the Great Depression, significantly in the early 1980s.
Step-by-step explanation:
The statement that modern globalization began around post WWI is false. The first wave of globalization actually began in the nineteenth century and was characterized by an increase in global exports as a share of global GDP from less than 1% in 1820 to 9% in 1913. This period showed a significant rise in international trade and economic integration, which was a precursor to modern globalization. However, this wave came to an abrupt halt due to the outbreak of World War I, which severed many economic connections.
The actual resurgence of globalization occurred much later, after a period of economic disintegration due to the two World Wars and the Great Depression. It was not until the early 1980s that global economic forces became as critical to the world economy as they had been before World War I. This process of reintegration and expansion of global interconnectivity in terms of trade, technology, and culture is what we refer to as modern globalization.
