Vestitorul & Electromagnetica (1946–2001)

FC Rapid II București was founded right after the end of the World War II, in 1946, as Vestitorul București. Vestitorul played for years at the level of Bucharest Municipality (Divizia D), before being bought by Electromagnetica, the main manufacturer of telecommunications equipment in Romania. Vestitorul București was renamed as Electromagnetica București in the 1960s, but important achievements did not appear in the following years, and Electromagnetica remained a fourth tier squad.

After the 1989 Romanian Revolution and fall of communism in the country, the factory was privatized and for the football team started its most glorious time. The club based in Veseliei Street promoted in the Divizia C, for the first time in its history, at the end of the 1994–95 season, after crowning as champions of Bucharest. At the end of the first season Electromagnetica was ranked 15th of 20, achieving its goal, the avoidance of relegation.^[2]

In the next seasons, Electromagnetica was a constant presence in the top of its Divizia C series, being ranked 3rd for three times in a row (1996–97, 1997–98, 1998–99) and as runner-up at the end of the 1999–2000 season, before winning its series and promoting in the Divizia B, at the end of the 2000–01 season. The club from Bucharest won the fourth series with an advance of only one point in front of former Divizia A side Flacăra Moreni.^[3]

Rapid II (2001–present)

After promotion, Electromagnetica started a collaboration with Divizia A side Rapid București, becoming its "satellite". From the perspective of Rapid, this new collaboration gave them the chance of having a second senior squad at the level of second division, where the players who finished the youth academy could be accommodated with the intensity of seniors level of football. On the other hand, for Electromagnetica was a mouth of oxygen, both from a financial point of view, as well as the transfers.

In its first season, Rapid-Electromagnetica collaboration was a fruitful one, the team being ranked 3rd, best performance in its entire history. In the next seasons the club was ranked: 6th (2002–03) and 13th (2003–04).

In the summer of 2004, Electromagnetica București has come under the sole control of FC Rapid București and was renamed as Rapid II București, but continuing to play its home matches in Vesliei Street, on Electromagnetica Stadium. At the end of the 2004–05 season, Rapid II was ranked 6th of 16, then, next season, relegating after being ranked 13th of 16, three positions under the red line.

However, during the 2005–06 season, Rapid II achieved one of the greatest performance in the club's history by eliminating Steaua București, in the Round of 32 of the Romanian Cup, with 8–7 at penalties, after the score was 0–0 during regular time and extra time.^[4][5][6]

Rapid II continued to play at the level of Liga III, but the financial crisis of 2007–08 and the problems of the parent club, FC Rapid București, made the team to struggle in mediocrity, finally withdrawing from the championship during the winter break of the 2012–13 season.

In the summer of 2019, after the promotion of Rapid in the Liga II, it was decided the re-foundation of Rapid II, the squad being enrolled in the Liga IV – Bucharest. Marian Rada was named the new manager of the "Burgundy Little Eagles".^[7]
