Operation Polo 1948: How Hyderabad Was Integrated into India

In the post-independence consolidation of modern India, the integration of the princely state of Hyderabad represents one of the most critical and dramatic episodes of territorial unification. In August 1947, when the British Raj transferred power to the independent dominions of India and Pakistan under the Indian Independence Act, the rulers of more than 560 princely states were given the choice to accede to either dominion or remain independent. The princely state of Hyderabad, ruled by Nizam Mir Osman Ali Khan (Asaf Jah VII), was the largest, most populous, and wealthiest princely state in the subcontinent, spanning over 214,000 square kilometers across present-day Telangana, northern Karnataka, and the Marathwada region of Maharashtra. Surrounded completely by Indian territory, the Nizam envisioned establishing Hyderabad as an independent sovereign monarchical state, refusing initial accession to the Indian Union.

To forestall immediate conflict, the Government of India and the Nizam entered into a formal Standstill Agreement on November 29, 1947, which maintained the administrative status quo for one year while negotiations continued. However, internal conditions within Hyderabad deteriorated rapidly into violent civil crisis. The Majlis-e-Ittehadul Muslimeen (MIM), led by the extremist ideologue Kasim Razvi, mobilized a private fanatical paramilitary force known as the Razakars. Numbering over 150,000 armed volunteers, the Razakars unleashed widespread terror, pillage, communal intimidation, and extortion against the civilian population, particularly targeting the eighty-five percent Hindu majority and railway lines traversing the state. Simultaneously, the rural peasantry of the Telangana region launched the historic Telangana Peasant Armed Struggle, led by the Communist Party of India (CPI) and the Andhra Mahasabha, seizing land from oppressive feudal landlords (doras) and battling the Nizam's state forces.

Faced with internal anarchy, cross-border raids into Indian territory, and attempts by the Nizam to procure modern weaponry from abroad, Deputy Prime Minister and Minister of States Sardar Vallabhbhai Patel, ably assisted by Ministry Secretary V.P. Menon, resolved on decisive military intervention. Rejecting indecision, Patel termed an independent Hyderabad "an ulcer in the belly of India." On September 13, 1948, the Indian Army launched a multi-pronged operation code-named "Operation Polo"—popularly termed a "Police Action" to prevent international complications at the United Nations. The operation was named after Hyderabad's extensive polo grounds, which numbered over seventeen. Commanded by Major General Joyanto Nath Chaudhuri under the overall operational direction of Lieutenant General Eric Goddard (Southern Command), Indian armed columns advanced from western Maharashtra and eastern coastal routes. Within 108 hours of coordinated military operations, the Nizam’s armed forces under Commander-in-Chief Major General Syed Ahmed El-Edroos surrendered on September 17, 1948, leading to the peaceful integration of Hyderabad into the Republic of India.
