Post-Independence Consolidation & Reorganisation

Following independence in 1947, India faced immense structural challenges involving partition rehabilitation, the political integration of over 560 princely states, and linguistic federal reorganization. Led by Sardar Vallabhbhai Patel and V.P. Menon, principalities including Junagadh, Hyderabad, and Kashmir were integrated into the Indian Union. The adoption of the Constitution in 1950 established a sovereign democratic republic, while the States Reorganisation Act of 1956 restructured internal administrative boundaries on linguistic lines based on the Fazal Ali Commission recommendations. India formulated an independent foreign policy anchored in the Non-Aligned Movement (NAM) and Panchsheel principles, navigated wars in 1962, 1965, and 1971, and initiated agrarian modernization through the Green Revolution in the late 1960s.
