Did Ambedkar and Nehru get along?
They were allies on some things and opponents on others, and the relationship is better described as a working alliance than a friendship. It was Nehru, leading the first government of independent India, who brought Ambedkar — a lifelong critic of the Congress — into his cabinet as Law Minister. That was a deliberate act of inclusion, and on the reform they both cared most about, the modernising of Hindu family law, they were on the same side.
But the alliance broke under strain. When the Hindu Code Bill met fierce opposition, the government did not spend the political capital to force it through whole, and Ambedkar concluded that the commitment behind him had failed. He resigned in 1951, and his resignation statement set out a wider list of dissatisfactions — over the treatment of the Scheduled Castes, over foreign and economic policy — not the bill alone. The partnership that had begun in inclusion ended in a pointed departure.
So the honest answer is: cooperation where their aims met, and real conflict where they did not. The bill they both wanted became law in pieces in the years after he left — the reform outlasted the breach between the two men who had tried to pass it together.
