JRD Tata and GD Birla were early 20th century Indian business leaders who helped lay the foundations for Indian industry. Tata established various companies like Tata Steel, Tata Motors, Tata Consultancy Services, and Air India. Birla established textile and other industries. Both supported India's independence movement and advocated for self-sufficiency in industry. In the post-independence era, India adopted a system of licenses and permits that constrained private business, but economic reforms since 1991 have enabled growth in private companies and India's rise as a global economic power. Key historical figures like Gandhi, Nehru, and Ambedkar shaped India's character and political system.
