Answer:
Sardar Vallabhbhai Patel is known as the 'Iron Man of India'. As the first Home Minister and Deputy Prime Minister of India, he 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. It was because of these qualities he is known as the 'Iron Man of India'.
