Despite losing 1-0 to Frosinone on Thursday, Spezia earned promotion to Serie A for the first time in their history after winning via the tiebreaker rule over two legs.
After each team won 1-0 in each leg respectively, Spezia won the tie after finishing higher than Frosinone in the regular Serie A season when they placed third.
In their entire 114-year existence, they have never featured in Serie A, but did play in the old First Division in the 1920s.
With a population of under 100,000 people, the town is one of the smallest ever to have a side play in the top flight.
Spezia will be joined by fellow promoted sides Benevento and Crotone in Serie A, with Lecce, Brescia and SPAL relegated with the new season getting underway on 19 September.
They actually gain promotion having won less than half of their league matches in 19/20, with them accumulating 17 wins, ten draws, and 11 losses over the course of the campaign.
Their top scorer was Emmanuel Gyasi with nine, while Paolo Bartolomei recorded the most assists with 11.
They had one of the best defensive records in the league, conceding 40 goals over the 38 games.
Two main contributors to this were the performances of defenders Elio Capradossi and Martin Erlic, who received the top two FootballCritic ratings for the season. Both are currently on a 68 FC Rating for their exploits.
Under head coach Vincenzo Italiano, they like to play out from the back and control possession. They had the second-highest tally for average passes completed per game with 487.14 which was bettered only by Crotone.
They are slightly shot-shy, though, as they attempt the 11th most average shots of any team in the league with 13.07 per 90 minutes.
