Step 1: What regionalism means:
Regionalism is the strong attachment people feel toward their own region - based on shared language, culture, history or economic interest - which can express itself either as a demand for regional development within the nation, or as separatist sentiment against it.
Step 2: Democracy's response - accommodation:
Indian democracy has largely managed regionalism through federalism, including the linguistic reorganisation of states (1956), granting statehood to regions demanding it (e.g., Jharkhand, Chhattisgarh, Uttarakhand, Telangana), and constitutional provisions for regional autonomy.
Step 3: Continuing challenges:
Despite this accommodation, regionalism still produces tensions such as inter-state river disputes, movements against migrant workers, and occasional secessionist demands in border regions, testing the strength of India's federal democratic framework.
Final Answer:
Indian democracy has managed regionalism mainly through federal accommodation (linguistic states, new statehoods), though inter-state disputes and occasional separatist demands remain ongoing challenges to national unity.
