The term referring to dynastic politics after 1947 is probably relegated to one single family in India; referencing to the first prime minister of India; Jawaharlal Nehru. He was a long standing leader in freedom struggle prior to 1947, and was the chosen one to lead India post 1947 freedom from the British. He was the leader of the country until his death. There was a gap from the Nehru family as Lal Bahadur Shastri http://en.wikipedia.org/wiki/Lal_Bahadur_Shastri was anointed the prime minister after the death of Pandit Nehru, and only after his death Mrs. Indira Gandhi (daughter of Pandit Nehru) became the prime minister. So, certainly there was a break in handing the leadership to Mrs. Gandhi. She had to wait until after Mr. Shastri’s demise before taking over as the leader of the nation. Since Mrs. Gandhi we have had successive governments and multiple prime ministers of India, including Rajiv Gandhi son of Mrs. Gandhi, where Rajiv Gandhi came into power after the assassination of Mrs. Gandhi while she was still in office. But the country has voted others to lead the nation, outside of the Nehru-Gandhi dynasty. We now have Mr. Modi, who doesn’t belong to any dynasty and comes from a really humble home. So, simply clubbing the nation’s leadership as dynastic politics is not completely true. There is quite a bit of family worship with the Nehru-Gandhi family, but there are several instances the public simply voted to what they feel is the right thing for the country rather than voting for a dynasty.
The country itself keeps it self politically active and also picks the leaders that represent a hope for tomorrow. India no longer is a docile nation. The young are well connected and well aware of the needs of their own families and their nation, and very capable of making their choices without looking at the dynasties of yester year. They are well informed and well connected and also well aware of their nations ever increasing demands. They will continue to make choices based on what they see best fit, rather than vote based on legacy.
