Why is Sardar Vallabhai Patel known as IRON MAN of India?

Because of his toughness, determination, and sheer strength of will. As the first Home Minister and Deputy Prime Minister of India, Patel organised relief for refugees in Punjab and Delhi, and led efforts to restore peace across the nation. Patel took charge of the task to forge a united India from the 565 semi-autonomous princely states and British-era colonial provinces. Using frank diplomacy backed with the option (and the use) of military action, Patel's leadership enabled the accession of almost every princely state. Hailed as the Iron Man of India, he is also remembered as the "Patron Saint" of India's civil servants for establishing modern all-India services. Patel was also one of the earliest proponents of property rights and free enterprise in India.
