India has maintained its unity despite its diverse religion.language,ethnicities, races etc. However its unity today is vulnerable due to several factors.

Factors that threaten India’s unity

• Regionalism: Regionalism tends to highlight interests of a particular region/regions over national interests. It can also adversely impact national integration. Law and order situation is hampered due to regional demands and ensuing agitation.
• Divisive politics: Sometimes, ascriptive identities such as caste, religion etc. are evoked by politicians in order to garner votes. This type of divisive politics can result in violence, feeling of mistrust and suspicion among minorities.
• Development imbalance: Uneven pattern of socio-economic development, inadequate economic policies and consequent economic disparities can lead to backwardness of a region. Consequently, this can result in violence, kickstart waves of migration and even accelerate demands of separatism.. For instance, due to economic backwardness of the North East region, several instances of separatist demands and secessionist tendencies have sprung up in the region.
• Ethnic differentiation and nativism: Ethnic differentiation has often led to clashes between different ethnic groups especially due to factors such as job competition, limited resources, threat to identity etc. E.g. frequent clashes between Bodos and Bengali speaking Muslims in Assam. This has been accentuated by son of the soil doctrine, which ties people to their place of birth and confers some benefits, rights, roles and responsibilities on them, which may not apply to others.
• Geographical isolation: Geographical isolation too can lead to identity issues and separatist demands. The North-East is geographically isolated from the rest of the country as it is connected with the rest of the country by a narrow corridor i.e the Siliguri corridor (Chicken’s neck). The region has inadequate infrastructure, is more backward economically as compared to the rest of the country. As a result, ithas witnessed several instances of separatism and cross-border terrorism, among others.
• Inter-religious conflicts: Inter-religious conflicts not only hamper relations between two communities by spreading fear and mistrust but also hinder the secular fabric of the country.
• Inter-state conflicts: This can lead emergence of feelings related to regionalism. It can also affect trade and communications between conflicting states. For instance, Cauvery river dispute between Karnataka and Tamil Nadu.
• Influence of external factors: Sometimes external factors such as foreign organizations terrorist groups, extremist groups can incite violence and sow feelings of separatism. E.g. Inter-Services Intelligence (ISI) has been accused of supporting and training mujahideen to fight in Jammu and Kashmir and sow separatist tendencies among resident groups.
• In-spite of the challenges posed by diversity, there can be no doubt on the role played by sociocultural diversity in sustaining and developing Indian society. Problem is not of diversity per se, but the handling of diversity in India society. The problems of regionalism, communalism, ethnic conflicts etc. have arisen because the fruits of development haven’t been distributed equally or the cultures of some groups haven’t been accorded due recognition.
• Hence, Constitution and its values must form guiding principles of our society. Any society which has tried to homogenize itself, has witnessed stagnation in due-course and ultimately decline. The most important example is this case is of Pakistan which tried to impose culture on East-Pakistan ultimately leading to creation of Bangladesh.
