The team of Fourth High School went together with players of Czarni Lwów in May 1906 to Kraków, where they tied with local students 1:1.
The change accelerated the club's growth, as soon afterwards it found a rich sponsor, Ludwik Kuchar, who was the owner of several cinemas located in Lwów and Kraków.
During the first years of existence, Pogoń played games against other local teams, and in 1907 its lineup consisted of the following footballers: Rysiak, Marion, Kawecki, Harasymowicz, Spanring, Rzadki, Pirozynski, Kleban, Dudryk, Karasinski, Zausner.
The first international game took place in May 1909, when Pogoń went to Košice, losing 0:5 to the champion of northern Hungary, Kassai AC.
In 1910, Pogoń joined the Austrian Football Association, which enabled the club to make contacts with several teams of the Austrio-Hungarian Empire.
In the fall of that year, after the Russians had withdrawn from Lwów, Pogoń played at home against Cracovia (October 1, 0:2), and then went to Kraków, to lose 0:7.
In 1917, while the conflict was still on, Pogoń played several matches versus teams of the Austrian Army units, stationed in the city.
When the hostilities had stopped, Lwów's side went on several away games across newly restored Poland, visiting Poznań, Warsaw, Łódź and Kraków.
The tournament was a propaganda exercise, with its main purpose to show Polish-speaking Upper Silesians the strength of Polish sports.
However, in the final tournament, Lwów's team was placed in the last (fourth) position, after the champions (Cracovia), Polonia Warsaw, and Warta Poznań.
It was then that Lwów's side won the first Polish championship, owing not only to a score of talented players, but also to Austrian coach named K. Fischer, who preferred an offensive, modern style of play.
In 1923, Pogoń again became the champions of Lwów's district of the Polish Football Association, winning 9 games and drawing 1 (with the record victory 21:1 versus Rewera Stanisławów).
Then, in the Eastern Poland group of the Championship it won all games, routing Lauda Wilno 13:0, and WKS Lublin 8:0 and 7:0.
The club purchased a very talented goalkeeper from Katowice, Emil Goerlitz, who also represented the national team of the country.
The lineup consisted of Gorlitz (goalkeeper), Olearczyk and Giebartowski (defenders), Hanke, Fichtel, Gulicz (midfielders), Slonecki, Batsch, W. Kuchar, Grabien and Szabakiewicz (forwards).
After the successes of 1925, Pogoń found itself in severe financial trouble, and the following year, the club was unable to contract any games with foreign opponents.
For the fourth time in a row, Pogoń turned out to be the best Polish team, beating on the way to championship Cracovia Kraków, WKS/Lublinianka Lublin, Warta Poznań (2:2, 7:1), and Polonia Warsaw (2:2, 2:0).
The 1926 success was the last championship for the club, and the winners fielded such players, as Lachowicz (goalkeeper), Olearczyk, Giebartowski (defenders), Deutschman, Fichtel, Hanke (midfielders), Urlich, Batsch, W. Kuchar, Grabien, Szabakiewicz (forwards).
It must be mentioned that Pogoń was stripped of 6 points, because it played a friendly game with Cracovia – the team that was banned by the League.
As the League was very time-consuming, Pogoń played only one international friendly, beating the Romanian side Fulgerul Bucharest 4:2 at home .
The lineup consisted of a generation of young players (Albanski, Jezewski, Deutschman, Nahaczewski, Maurer, Michal Matyas, Adolf Zimmer), who were supported by veterans – Waclaw Kuchar, Hanke, or Szabakiewicz.
In international friendlies, Pogoń beat 3:0 Jahn Czernowitz, ethnic German side from Cernauti, and lost to III Kerulet FC 3:5, 1:2, as well as Atilla Miskolc 1:3.
After purchasing Karol Kossok from Cracovia and Edmund Majowski from AKS Chorzów, Pogoń finished on the 4th spot, only two points behind the champion, Garbarnia Kraków.
The team finished Ekstraklasa games on the 6th position, and in summer of that year, Pogoń hosted the champion of Bulgaria, Levski Sofia, winning 1:0.
In 1937, Pogoń played several international friendlies, including two games with exotic side Hapoel Tel Aviv (both won 4:2 and 7:2).
Following the German-Soviet invasion of Poland, which started World War II in September 1939, the city was occupied by the Soviet Union.
Two pre-war footballers, Alfred Zimmer and Tadeusz Kowalski, and athlete Karol Cybulski were among Poles murdered by the Russians in the large Katyn massacre in April–May 1940.
[1] After the war, when it became clear that Lwów would no longer belong to Poland, its Polish citizens were forced to leave the city.
Odra Opole was originally called Lwowianka, but the name was disliked by Communist authorities and had to be changed some time in late 1940s.
