Sri Lankan nationalism is a political and cultural movement that emphasizes the identity and interests of the Sri Lankan people. It seeks to promote unity among the diverse ethnic groups, including Sinhalese, Tamils, and Muslims, while also advocating for the preservation of Sri Lankan culture, language, and heritage. The movement has been influenced by historical events, such as the struggle for independence from British colonial rule in 1948. Over the years, it has played a significant role in shaping the country's policies and social dynamics, particularly during the Sri Lankan Civil War, which highlighted ethnic tensions and the quest for self-determination among different communities.
