In India, the concept of single citizenship is adopted from

The concept of single citizenship in India was adopted from the British Constitution of England. The Indian Constitution grants all residents of the country single citizenship, regardless of their birthplace or where they live. This means that Indians do not represent any state, and only have one identity as citizens of the Indian Union. The founders of the Constitution believed that dual citizenship would encourage regionalism and other disintegrating tendencies that could endanger the country's security and integrity. They also believed that dual citizenship would make people think more in terms of the state than the country as a whole. Single citizenship in India promotes patriotism and fundamental freedoms, such as the freedom to travel and live anywhere in the country.
