The history of Újpest FC begins with its founding in 1885. The club have won the Hungarian League 20 times and the Hungarian Cup 8 times.

Early years The club was founded on 16 June 1885 by school teacher János Goll in Újpest, a separate city in those times, just next to the borders of Budapest under the name Újpesti Torna Egylet. It was formed first as a general athletic club, performing gymnastics and fencing, and its motto was "Soundness, Strength, Harmony" (). In 1899, a football club was formed in the city of Újpest under the name Újpesti FC and with the same colours, purple and white. The first official match of Újpesti FC was a 1:1 draw on 29 April 1900 against III. Kerületi TVE. In 1901 the two clubs (UTE and Újpesti FC) merged and formed the football division of Újpesti TE and the club joined the second division of the newly formed Hungarian League. Újpest is ever since one of two teams in Hungary that have never missed a season since the beginnings of league games in the country.

Újpest were promoted to the first division in 1904 and they have managed to play on top flight ever since except for the season of 1911–12 when they finished as champions of the second division after a one-year relegation.

The first golden era

The club built the new Megyeri úti stadion in 1922, which marked the opening of a new era of medal collection. The legendary "Fogl-gate" (Fogl-gát in Hungarian), a massive defending formation of brothers Károly Fogl II and József Fogl III for both the national team and Újpest was the key point for the club's successes. From 1926, after the introduction of professional football in Hungary, the football team was playing under the name Újpest FC. The late 1920s and 30s brought the first golden age of the club, marked by finishing on top of the Hungarian first division 5 times and international cup success, including two Mitropa Cup titles in 1929 and 1939, and also the Cup of Nations title in 1930. In the 1938–39 season, Béla Guttmann coached the team to wins of the Hungarian League and the Mitropa Cup (the precursor to the European Cup). The team finished on one of the first three positions in every season between 1926 and 1942, and played in five cup finals during the 1920s and 30s.

Újpest gave 5 players for the World Cup of 1938 to silver medalist Hungary including György Szűcs, Antal Szalay, István Balogh I, Jenő Vincze, and the rising star of Hungarian football, Gyula Zsengellér.

After World War II The first years after World War II saw the second golden era of Újpest, and saw the club on the top of the championship three times in a row, once even giving 9 players to the Hungary national team. Players like Ferenc Szusza, Béla Egresi, Sándor Balogh II, István Nyers or Mihály Nagymarosi were setting records of winning 30 consecutive games, or scoring 187 goals in one single season. Béla Guttmann in early 1947 rejoined Újpest FC, then known as Újpesti TE, and won another Hungarian League title.

In 1950 the communist government chose Újpest as official club of the police and renamed them Budapesti Dózsa (after György Dózsa), a fairly common practice in Eastern Bloc countries (except that in other places "police clubs" were typically named Dinamo/Dynamo) and two decades of moderate league and cup success followed. In 1951, defender Sándor Szűcs, after being executed by the communist government for high treason during a secret pre-arranged trial, became a martyr of the club. As a result of the less successful years, Mihály Tóth was just one of two Újpest players in 1954 World Cup squad, and the only one to play in the final. During the 1956 revolution, the club renamed itself Újpesti TE; however, after the revolution was pulled down by the Soviets, the Hungarian government – unlike for FTC or MTK – didn't let the club use their old name. This resulted the name Újpesti Dózsa, which was referring both to the district and to the police. After 13 years without a league title, Újpest became champions of Hungary in 1959–60, and reached the Cup Winners' Cup semi-final in 1962 with the help of the new star, János Göröcs.
