Globalization or globalisation is the process of interaction and integration among people, companies, and governments worldwide. As a complex and multifaceted phenomenon, globalization is considered by some as a form of capitalist expansion which entails the integration of local and national economies into a global, unregulated market economy.[1] Globalization has grown due to advances in transportation and communication technology. With the increased global interactions comes the growth of international trade, ideas, and culture. Globalization is primarily an economic process of interaction and integration that's associated with social and cultural aspects. However, conflicts and diplomacy are also large parts of the history of globalization, and modern globalization.

Economically, globalization involves goods, services, the economic resources of capital, technology, and data.[2][3] Also, the expansions of global markets liberalize the economic activities of the exchange of goods and funds. Removal of cross-border trade barriers has made formation of global markets more feasible.[4] The steam locomotive, steamship, jet engine, and container ships are some of the advances in the means of transport while the rise of the telegraph and its modern offspring, the Internet and mobile phones show development in telecommunications infrastructure. All of these improvements have been major factors in globalization and have generated further interdependence of economic and cultural activities around the globe.[5][6][7]
