This document compares Belgium and Sri Lanka in terms of their linguistic diversity and the resulting political tensions. Belgium has Dutch and French-speaking populations, while Sri Lanka has Sinhala and Tamil populations. Belgium adopted a federal system that recognizes both languages and gives regional autonomy, avoiding civic tensions. In contrast, Sri Lanka took majoritarian measures favoring Sinhala that denied Tamils equal rights and led to the civil war seeking a separate Tamil state. The document argues Belgium's system has helped maintain unity while accommodating diversity.
