Atromitos Athinon

Atromitos was officially founded on 31 May 1923 when Kalomvounis, Petos, Glykofridis, Stathopoulos, Synodinos, Rigopoulos, Stamatopoulos, and other students living in Victoria Square, (which was then called Kyriakou Square) decided to form a football team. That same year, Vaggelis Stamatis, a mathematics teacher and member of the Panhellenic football league, joined Atromitos' administration board – because of his prominence in pre-war Greek football history, Stamatis' involvement increased the new team's stature in Athenian football.

In 1924, Atromitos was accepted into the Greek football league. At the time, Atromitos played at Aris Park, which was the home ground of Panellinios and Panathinaikos. During their first season in the league's first division, they ended in third place behind Panathinaikos and AEK. In 1928, they defeated Goudi 4–3 in the final game at Rouf Stadium to become champions of Athens. That same year, they took part in the first Panhellenic Championship as Athens champions, which was organised by the HFF. On 24 May 1928, they were beaten 3–1 by Aris Thessaloniki (who later became champions) in an away game, and were defeated again on 3 June by Ethnikos Piraeus (5–0). On 10 June, they managed a draw at home against Ethnikos (1–1), before losing again to Aris 3–1 seven days later. Overall in the national championship, Atromitos finished third.

During the following two years, Atromitos stayed in the upper part of the first division of Athens, and in 1929, they finished third behind Panathinaikos and AEK. They repeated the feat in 1930 but they were relegated from the first division of Athens in 1931, as they came last with only one point.

In 1932, Ioseph Chourouktsoglou and Nikolaos Epioglou decided to move Atromitos to Peristeri. Earlier, it was located in the same area as Panathinaikos, and they had found it hard to establish a large fan base or develop a unique identity. There, they formed a merger with the local team of Astir Peristeriou (meaning "Star"), from which comes the crest of Atromitos, a blue star.

Before occupation of Greece, they played again in Panhellenic championship in the season of 1938–39.

Atromitos played in the second division until May 1972 when, under the coaching of Savvas Papazoglou, they were re-promoted to the first level. It proved a change too hard to handle, and they were demoted the following year. In 1975, a better-prepared Atromitos returned to the first division with a large fanbase, and ended the year in 13th place, securing their spot in the top flight. In 1976, they improved to end the season in 9th place, the best in the club's history. But, they were relegated in 1977.

By 1981, Atromitos had succeeded in attracting renowned players such as Stylianopoulos, Álvarez, Toskas and Athanasopoulos. However, despite high expectations, the club finished last in the top flight, and once more returned to the lower divisions. After years of playing in the third division, Atromitos won promotion back to the second division in May 2002 by beating Levadiakos at Patras Stadium. The team played again in the top flight between 2005 and 2008 by merging with Chalkidona and returned to the top flight after playing one season in the second division in 2008–09.

In the 2010–11 season, Atromitos made a historic run to the Greek Cup Final. However, they lost 3–0 to AEK.

Atromitos finished the 1st half of the season in 4th place, together with Asteras Tripolis and 14 points from the top, but 4 points from 6th place, that doesn't redirect to the playoffs. On 6 January 2013, at the debut of Nikos Anastopoulos in the coaching position and the Portuguese footballer Fabio, Atromitos beat Kerkyra 2–0, with two headers. From Sokratis Fytanidis at the 26th minute and from Stathis Tavlaridis at the 31st minute. In other words, the win was awarded to the team by the two centre backs. The team stayed in 4th with Asteras Tripolis, but now 6 points from the 6th place. One matchday later, they managed to get the 0–0 from PAOK at Toumba, retaining the 6 points difference from PAS Giannina. On Matchday 18, they beat Platanias 1–0, getting to be only 3 points from 2nd place. The goal was scored by Eduardo Brito.

For the 2015–16 season, Atromitos has achieved an important qualification to the UEFA Europa League playoffs after recording two wins against AIK Stockholm, 3–1 in the first game in Sweden and 1–0 in the rematch at Peristeri Stadium. There they faced highly rated Fenerbahçe S.K. of Turkey. They lost 0–1 in the first match at Peristeri Stadium and 0–3 in the rematch in Turkey and were eliminated.

At 21 June 2017, Atromitos announced Damir Canadi as the new head coach of the club. At 23 October 2017, Atromitos won AEK 0–1 in an away game and then recognition began. Atromitos finished 4th at the 2017–18 season.

On 20 March 2017, announced that Canadi will manage the club also for the 2018–19 season.
