Globalization refers to the increasing integration of economies and cultures around the world. It involves the reduction of trade barriers between nations, the growth of multinational corporations operating in multiple countries, and the spread of technology and communication globally. Globalization has occurred in waves throughout history as empires and advances in technology have facilitated increased trade and cultural exchange over larger regions. While globalization has connected people and economies worldwide, it has also been criticized for homogenizing cultures and prioritizing the interests of wealthy nations over disadvantaged populations.
