What if Sardar Patel or Netaji Bose would be India's first prime minister?

History can be intellectually very stimulating if alternative scenarios are visualised. Even the recent trends in some major exam's questioning pattern seem to suggest that students must develop this thought process, as it needs real depth to be able to write rationally on alternative possibilities. In fact, the UPSC 2015 Mains papers clearly indicated it!

So, a good question - Let us suppose that Pandit Nehru did not become the first PM of India. What would have happened?

This answer is based on pure speculation. Kindly bear.

India if Sardar Patel were to become the first PM, and continued for some years -

Pakistan to the UN? Never!

1. Having integrated India, he would have gone real heavy on the Kings and Princes that played the fool during the process of integration. Their falling-in-line would have been ensured very fast.
2. He would have made them pay the price pretty quickly - the Privy Purses would have been abolished perhaps by 1955 itself (rather than in 1971 as done by Indira Gandhi) [ Privy Purse in India ]
3. The private banking industry in India would have collapsed due to this pretty fast, and nationalisation would've happened by 1960 itself. 
4. The Congress may have seen a vertical split right after the First General Elections. The faction led by Pandit Nehru would have posed a huge challenge to Patel's leadership.
5. The Kashmir issue would have taken a different shape altogether - it would never have been internationalised, and no appeal to the UN would ever be made. Bilateral would have meant completely Unilateral!
6. Pakistan would have thought once more before pushing the tribal forces into Kashmir in 1948.
7. Bye bye NAM.
8. Bye bye Personal Law System. Welcome Uniform Civil Code.
9. Perhaps India would have discovered Netaji Bose's real whereabouts in the 1950s.(Warning - pure, heavily loaded speculation)
10. Goa would have been in India by 1952 at the most :)
11. Perhaps no IITs and IIMs but more of regionally empowered institutions
