India faced many challenges after independence in 1947, including integrating princely states, rehabilitating refugees, and establishing a national language and government. The nation established a Planning Commission to facilitate economic development and adopted a constitution on January 26, 1950. Meanwhile, India pursued a policy of non-alignment during the Cold War and worked to peacefully resolve conflicts with China and Pakistan, fighting several wars over territorial disputes in the following decades. After 70 years, India has grown into one of the world's largest democracies and economies.
