American CenturyThe American Century is a characterization of the period since the middle of the 20th century as being largely dominated by the United States in political, economic, and cultural terms. It is comparable to the description of the period 1815–1914 as Britain's Imperial Century. The United States' influence grew throughout the 20th century, but became especially dominant after the end of World War II, when only two superpowers remained, the United States and the Soviet Union.
Pacific CenturyThe Pacific Century (and the associated term Asia-Pacific Century) is a term that has been used to describe the 21st century through analogy with the term American Century. The implicit assumption underlying the usage of the term is that the 21st century will be dominated, especially economically, by countries in the Asia-Pacific region and major economies on the Pacific, most dominantly China (both the People's Republic and Taiwan) ASEAN countries, Japan, South Korea, India, New Zealand and Australia, and to an extent, the United States.
Potential superpowerA potential superpower is a state or other polity that is speculated to be—or to have the potential to soon become—a superpower. Currently, only the United States fulfills the criteria to be considered a superpower. However, the United States is no longer the only uncontested foremost superpower and the world's sole hyperpower to dominate in every domain (i.e. military, culture, economy, technology, diplomatic). Since the 1990s, China, the European Union, India, and Russia have been described as potential superpowers.
Asian CenturyThe Asian Century is the projected 21st-century dominance of Asian politics and culture, assuming certain demographic and economic trends persist. The concept of Asian Century parallels the characterisation of the 19th century as Britain's Imperial Century, and the 20th century as the American Century. A 2011 study by the Asian Development Bank found that 3 billion Asians (so 56.6% of the estimated 5.3 billion total inhabitants of Asia by 2050) could enjoy living standards similar to those in Europe today, and the region could account for over half of global output by the middle of this century.
SuperpowerSuperpower describes a state or supranational union that holds a dominant position characterized by the ability to exert influence or project power on a global scale. This is done through the combined means of economic, military, technological, political, and cultural strength as well as diplomatic and soft power influence. Traditionally, superpowers are preeminent among the great powers.
HegemonyHegemony (hɪˈdʒɛməni, hɪˈɡɛməni, ˈhɛdʒəmoʊni) is the political, economic, and military predominance of one state over other states. Hegemony can be regional or global. In Ancient Greece (8th BC – AD 6th ), hegemony denoted the politico-military dominance of the hegemon city-state over other city-states. In the 19th century, hegemony denoted the "social or cultural predominance or ascendancy; predominance by one group within a society or milieu" and "a group or regime which exerts undue influence within a society".
