Globalization has influenced religion in several ways. It has allowed the spread of religions across borders through increased movement of people, trade, and cultural exchange. Major religions like Buddhism first spread globally through trade routes like the Silk Road. Pilgrimages and tourism have also contributed to the globalization of religions. The Crusades illustrated how Christianity drove early globalization efforts. However, critics argue that globalization can lead to cultural homogenization and a loss of diversity as local traditions are erased. It has also contributed to both religious secularization and religious conservatism in different societies. Managing religious diversity and reducing conflicts remains an ongoing challenge of globalization.
