The BJP wins its first mandate
What happened
Indian National Congress's hold on Arunachal Pradesh ended for the first time in years, and Bharatiya Janata Party won by a landslide.
The BJP won 41 of the 60 seats, enough for a supermajority.
The Janata Dal (United) finished a distant second, with 7 seats.
What changed
For the first time in this run of elections, power changed hands through a vote, not through defections.
The BJP grew from just 11 seats at the previous election to 41 this time.
30 seats — half the assembly — flipped from the INC to the BJP, a collapse for the party that had long governed the state.
Two parties, JD(U) and NPEP, won seats in Arunachal Pradesh for the first time.
Notable numbers
A few numbers from that election stand out.
The closest race: Seppa East, Arunachal Pradesh was decided by just 29 votes, the smallest margin — how far ahead the winner finished, in votes, over whoever came second — of the year.
At the other end, Thrizino-Buragaon, Arunachal Pradesh was won by 67.7% of the vote.
Mariyang-Geku, Arunachal Pradesh recorded the best turnout of the election, 94.3% — the share of registered voters who actually cast a ballot.
Bordumsa - Diyun, Arunachal Pradesh drew the most candidates of any seat that year, 10 in all.
The backdrop
The party that won this election had already been governing the state since an earlier wave of defections.
Following a 2015-16 leadership dispute inside the ruling Congress party, Chief Minister Pema Khandu and 43 MLAs joined the People's Party of Arunachal on 16 September 2016. On 31 December 2016 that PPA legislature party merged into the Bharatiya Janata Party, giving the BJP a governing majority without a fresh election.
