Some notes:

— In the timeline, years in black are Lok Sabha election years, and correspond to the year in which elected Prime Ministers came to power. The timeline starts the term of each Prime Minister on the date they were sworn in.

— The Prime Minister with the shortest term is Gulzarilal Nanda. Even though Atal Bihari Vajpayee resigned after 13 days, he continued to serve for three more till the next Prime Minister was chosen.

— Indira Gandhi was the only Prime Minister assassinated in office. Rajiv Gandhi was assassinated out of office while campaigning. The Indian National Congress had lost the previous elections.

— Only twice have governments fallen due to the loss of a vote of confidence. In all other cases the Prime Minister resigned when the coalition could not form a majority.
