On June 4, the Election Commission of India will count hundreds of millions of votes in a few hours, announcing the results of the country’s 18th Lok Sabha election, after six weeks and seven phases of what has been the world’s largest-ever democratic exercise.

The results will determine who will form India’s next government. Prime Minister Narendra Modi’s Bharatiya Janata Party (BJP) will be seeking a third straight term in office, while the Congress party-led opposition will be hoping to upstage them.

Here’s a look at how the country voted for its parliament in its previous 17 elections since gaining independence in 1947.
