Globalization, integration of the world’s economies, politics, and cultures. German-born American economist Theodore Levitt has been credited with having coined the term globalization in a 1983 article titled “The Globalization of Markets.” The phenomenon is widely considered to have begun in the 19th century following the advent of the Industrial Revolution, but some scholars date it more specifically to about 1870, when exports became a much more significant share of some countries’ gross domestic product (GDP). Its continued escalation is largely attributable to the development of new technologies—particularly in the fields of communication and transportation—and to the adoption of liberal trade policies by countries around the world.

Social scientists have identified the central aspects of globalization as interconnection, intensification, time-space distanciation (conditions that allow time and space to be organized in a manner that connects presence and absence), supraterritoriality, time-space compression, action at a distance, and accelerating interdependence. Modern analysts also conceive of globalization as a long-term process of deterritorialization—that is, of social activities (economic, political, and cultural) occurring without regard for geographic location. Thus, globalization can be defined as the stretching of economic, political, and social relationships in space and time. A manufacturer assembling a product for a distant market, a country submitting to international law, and a language adopting a foreign loanword are all examples of globalization.

Of course history is filled with such occurrences: Chinese artisans once wove silk bound for the Roman Empire (see Silk Road); kingdoms in western Europe honoured dictates of the Roman Catholic Church; and English adopted many Norman French words in the centuries after the Battle of Hastings . These interactions and others laid the groundwork for globalization and are now recognized by historians and economists as important predecessors of the modern phenomenon. Analysts have labeled the 15th to 18th century as a period of “proto-globalization,” when European explorers established maritime trade routes across the Atlantic and Pacific oceans and encountered new lands. Integration prior to this time has been characterized as “archaic globalization.”

What distinguishes the process of modern globalization from those forms of global integration that preceded it are its pace and extent. According to some academics, three distinct eras of modern globalization can be identified, each of them marked by points of sudden acceleration in international interaction. Under this scheme, the “first globalization” era refers to the period between approximately 1870 and 1914, during which new transportation and communication technology decreased or eliminated many of the drawbacks to distance. The “second globalization” era is said to have lasted from roughly 1944 to 1971, a period in which an international monetary system based on the value of the U.S. dollar facilitated a new level of trade between capitalist countries. And the “third globalization” era is thought to have begun with the revolutions of 1989–90, which opened the communist Eastern bloc to the flow of capital and coincided with the creation of the World Wide Web. Some scholars argue that a new period of globalization, the “fourth globalization,” is underway, but there is little consensus on when this era began or whether it is truly distinct enough to merit its own designation.

New levels of interconnectedness fostered by globalization are credited for numerous benefits to humanity. The spread of industrial technology and the resulting increase in productivity have contributed to a reduction in the percentage of the world’s population living in poverty. The sharing of medical knowledge has dramatically decreased the incidence of once-feared diseases and even eliminated smallpox. And economic interdependence among countries discourages war between them.

However, the implementation of globalization has been much criticized, leading to the development of the anti-globalization movement. Opponents of globalization—or at least, globalization in its present form (see neoliberal globalization)—represent a variety of interests on both the political left and right. Labour unions disdain multinational companies’ ability to move their operations to countries with cheaper labour; Indigenous peoples rue the difficulty of maintaining their traditions; and leftists object to the neoliberal character of the new world economy, arguing that the capitalist logic on which they contend globalization is based leads to asymmetrical power relations (both internationally and domestically) and transforms every aspect of life into a commodity. Right-wing critics of globalization believe that it threatens both national economies and national identity. They advocate national control of a country’s economy and rigidly restricted immigration.

Globalization has also produced effects that are more universally worrisome. Expanded transportation networks facilitate not only increased trade but also the spread of diseases. Undesirable trade, such as human trafficking and poaching, has flourished alongside legitimate commerce. Moreover, the pollution generated by the world’s modernization has resulted in global warming and climate change, threatening Earth’s very habitability.

Whether globalization will adapt to these problems remains to be seen, but it is already changing again. For example, globalization began in the 19th century with an explosion in exports, but, even before the COVID-19 pandemic that swept through the world in 2020 resulted in global lockdowns, trade as a share of many countries’ GDP had fallen. It can be argued that the global supply chains today rely more on knowledge than on labour. And services now constitute a larger share of the global economy than goods. A “fourth globalization” might indeed be here—or at least on the way.
