when did the usa join the core of the modern world system
Core countries Core countries do not always stay core permanently. Throughout history, core nations have been changing and new ones have been added to the core list. The most influential countries in the past have been what would be considered core. These were the Asian, Indian and Middle Eastern empires in the ages up to the 16th century, prominently India and China were the richest regions in the world until the 15th century, when the European powers took the lead, although the major Asian powers such as China were still very influential in the region. Europe remained ahead of the pack until the 20th century, when the two World Wars turned disastrous for the European economies. It is then that the victorious United States and Soviet Union, up to late 1980s, became the two hegemons, creating a bipolar world order. The heart of civilisation consists of Western Europe, North America, Australasia and Japan. The population of the core is by far the wealthiest and best educated on the planet.
History of the United States (1945–64) For the United States of America, 1945 to 1964 was a time of high economic growth and general prosperity. It was also a time of confrontation as the capitalist United States and its allies politically opposed the Soviet Union and other communist countries; the Cold War had begun. African Americans united and organized, and a triumph of the Civil Rights Movement ended Jim Crow segregation in the South.[1] Further laws were passed that made discrimination illegal and provided federal oversight to guarantee voting rights.
