This emergency lasted through the Indo-Pakistani War of 1965 and up to 1968. It was revoked in 1968. The second emergency in India was proclaimed in 1971 by President V. V. Giri on the eve of the Indo-Pakistani War of 1971. The first two emergencies were in the face of external aggression and War. They were hence external emergencies.
