Amid a global pandemic, it has gone by largely unnoticed - not least because the crisis also kept out election observers from the East African Community (EAC), the only foreign group the government accredited.
The ruling party has grown increasingly isolationist since the last election in 2015 when outgoing President Pierre Nkurunziza decided to stand for a third term, sparking months of protests.
The results - announced by the electoral commission three days after the vote - give the CNDD-FDD's candidate Evariste Ndayishimiye 68% of the vote.
Ndayishimiye's balancing act
One of the new president's key challenges on taking office will be to balance the various interests within the ruling party.
Ndayishimiye is new in the job and has made subtle overtures to international bodies in recent months, meeting with the AU Chairperson Moussa Faki and EAC officials.
