On 31 March 1929, Juventus won their twelfth consecutive league match, setting a club record that lasted until 2015.
It was the last season in Italy under the old regional structure, which would give way to a new national league the following year. Juventus, winners of the title in 1905 and 1926, had finished second in their regional group the previous season (out of eleven teams), and needed only to finished eighth out of an expanded group of sixteen teams in order to qualify for the new top flight, Serie A.
They got off to a strong start in the fall, going undefeated in their first eight matches (which included a pair of 11-0 wins over Fiorentina and Fiumana) before losing to Brescia on 9 December. They quickly rebounded in their next game, a 3-4 win over Pro Vercelli on 16 December, to start their record streak. More victories followed, capped by a twelfth consecutive win, 1-3 over Fiumana, on 31 March.
Bologna ended the streak by holding Juventus to a 1-1 draw on 14 April. With eight games remaining, Juventus limped to the finish line with four losses and four draws, but it was enough to earn them second place in the table and a guaranteed spot in Serie A.
The record held until 2015, when they won a streak of 13 straight league matches that started toward the end of the previous season. They further extended the streak to 15 in the 2015-16 season.
