Unirea Slobozia

Unirea Slobozia was founded in 1955 under the name Combil Slobozia, initially under the patronage of the local Ialomița combine for the production and industrialisation of pork meat. The club spent its first fifteen seasons in the regional and county championships, during which it competed under several names, including Avântul, Voința and Energia.

In the 1969–70 season, Energia earned promotion to Divizia C after winning the Ialomița County Championship and defeating ITA București, the Bucharest Municipal champions, in the promotion play-off, drawing 0–0 at home and winning 2–1 away.

Meanwhile, the club was taken over by the Amonil chemical fertiliser combine and, following promotion to the third division, was renamed Azotul Slobozia. The club spent most of the 1970s as a mid-table Divizia C side, finishing 6th in Series III in 1970–71, 8th in Series V in 1971–72, 4th in 1972–73, 8th in 1973–74, 3rd in both 1974–75 and 1975–76, and 7th in 1976–77. After moving to Series IV, Azotul finished 5th in 1977–78 and 2nd in 1978–79. The club was renamed Amonil Slobozia in 1979 and continued in Divizia C, finishing 2nd in 1979–80, 9th in 1980–81 and 7th in Series V in 1981–82.

In the summer of 1982, the club was renamed Unirea Slobozia. Under the guidance of Ion Păciulete, Unirea won Series IV of the 1982–83 Divizia C and earned promotion to Divizia B for the first time. The squad included Soare, Ionescu, Tache, Drăguț, Cristea, Borș, Gogan, Mateiu, N. Nicolae, Gh. Nicolae, Lazăr, Lupu, Păun, Liviu, Vintilă, Constantinescu and Damaschin.

In its first season in the second division, Unirea strengthened its squad with players such as Gheorghe Tătaru, who also served as player-coach, alongside Toader, Niță, Jercălău, Ene, Hadadea, Marchidan, Petrescu and Simionov. However, the team endured a difficult campaign, finishing 17th and being relegated back to Divizia C. Following its return to the third division, the club struggled to recover and finished 11th out of 16 teams in 1984–85, level on points with four other clubs and surviving on goal difference.

Unirea earned promotion back to Divizia B at the end of the 1985–86 season, pulling clear during the final two rounds following a close battle with Sportul 30 Decembrie. The team, managed by Constantin Dinu, included Soare, Suciu, Șoltuz, Drăguț, Gogan, Cristea, Țanicoiu, Ene, Iordache, Dumitru, Lupu, Constantin, who scored 34 goals, Vintilă, Păun and Dănilă.

In the 1986–87 season, Unirea was managed by Nicolae Dumitru during the first part of the campaign and Emanoil Hașoti during the second. Reinforced by players such as Istrate, Dinu, Cîrîc, Mihale, Gache, Prepeliță, Roșu, Bătrâneanu and Mustacă, the club finished 7th in Series I. Its stay in the second tier lasted only two seasons, as Ialomițenii finished 16th in 1987–88 and were relegated to Divizia C.

Promotion was immediate. Under Constantin Prepeliță as player-coach during the first part of the season and Vasile Dobrău during the second, Unirea won Series IV of Divizia C in the 1988–89 campaign. Slobozenii also reached the quarter-finals of the 1988–89 Cupa României, eliminating two first-division teams, Universitatea Cluj 1–0 in the first round and Bihor Oradea 2–0 in the second round, before losing 1–3 to Steaua București. The squad included Istrate, Matei, Drăguț, Țanicoiu, Cîrîc, Nedelciu, Iordache, Ioniță, Paraschiv, Prepeliță, Proșteanu, Vlase, Mîndru, Vintilă, Piștalu, Costin, Iovănescu and Constantin.

In Divizia B, Unirea competed in Series I, finishing 13th in 1989–90, just one point above the relegation zone, followed by 8th place in 1990–91 and 9th in 1991–92. However, the 1992–93 season ended with the club in last place out of 18 teams, resulting in relegation after four seasons in the second division.

In the summer of 1993, the club was renamed ASA 93 Slobozia and competed in Series II of the 1993–94 Divizia C, finishing 19th out of 20 teams and being relegated to the Ialomița County Championship. After reverting to the name Unirea Slobozia, the club won the Divizia D Ialomița title in the 1997–98 season and defeated Șantierul Naval Tulcea, the Tulcea County champions, 2–0 in the promotion play-off, returning to the third division after a four-year absence.

In Divizia C, Unirea competed in Series II, finishing 12th in 1998–99 and 14th in 1999–2000. However, the club encountered financial problems in the early 2000s and withdrew after the first half of the 2000–01 season, being subsequently dissolved.

The club was re-founded in 2004 as AFC Unirea 04 Slobozia and secured a place in the 2005–06 Divizia C, finishing 7th in Series II. It followed this with 6th place in 2006–07, 8th in 2007–08, 4th in 2008–09 under Marian Catană and 3rd in 2009–10, a campaign in which Ion Răuță was replaced by Constantin Prepeliță towards the end of the season.

Under Prepeliță, the Yellow and Blues reached the fifth round of the 2010–11 Cupa României, where they were eliminated 3–4 on penalties by Viitorul Constanța, and finished as runners-up in 2010–11, one point behind Callatis Mangalia. Viorel Gheorghe finished as the series' top scorer with 23 goals, as Unirea achieved its best league finish in nineteen years.

In the 2011–12 season, Constantin Prepeliță was appointed general director, while Ion Ionescu took over as head coach. Unirea won its series and secured promotion to Liga II three rounds before the end of the season. The squad included Dobre, Oprea, Judeanu, Lazăr, Stan, Roșu, Bozean, V. Toma, Cristian, Sescioreanu, Soare, Macare, Cristea, Ivașcă, Drăguț, C. Toma, Ibrian, Tudor, Patrianca, V. Gheorghe, T. Gheorghe, Zevedei, Stanciu, Ștefan and Anghel.

Ahead of the 2012–13 season, Ion Ionescu was replaced by Marin Dună as head coach. Among the club's signings was Adrian Mihalcea, who was approaching the end of his playing career and was regarded as one of the most prominent products of Slobozia football. Dună led Unirea to the fourth round of the 2012–13 Cupa României, where it was eliminated 1–3 by Săgeata Năvodari, and to a 7th-place finish in Series I of Liga II.
