Host nation Azerbaijan was represented by 285 athletes at Baku 2015, winning 21 gold, 15 silver and 20 bronze medals.
The country ranked second in the final standings, only behind Russia.
Judoka Elmar Gasimov served as Azerbaijan's flagbearer at the Opening Ceremony, while boxer Teymur Mammadov, the men's 81 kilograms champion, did so at the Closing Ceremony.
According to a survey among 150,000 youngsters in Azerbaijan, 80 per cent of people there believe Baku 2015 boosted the international image of the nation.
The build-up to the Games was overshadowed by protests about Azerbaijan's human rights record and its relationship with Armenia.
The event, however, was widely considered a success.
Nearly 6,000 athletes representing all 50 members of the European Olympic Committees took part in the Games, comprising 253 events in 20 sports.
