The first official match of Újpesti FC was a 1:1 draw on April 29, 1900 against III. Kerületi TVE. In 1901 the two clubs (UTE and Újpesti FC) merged together and formed the football division of Újpesti TE and the club joined the second division of the newly formed Hungarian League. Újpest is one of only two teams in Hungary that have never missed a season since the start of league games in the country.

Újpest were promoted to the first division in 1904 and they have managed to stay in the top flight ever since, except for season 1911-12, when they finished as champions of the second division, after previously being relegated.

The club built the new Megyeri road stadium in 1922, which marked the opening of a new era of trophy success. The legendary "Fogl-gate" (Fogl-gát in Hungarian), a strong defensive formation, made up 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 played under the name Újpest FC.

The late 20's and 30's brought the first golden age for the club, which saw them finish top of the Hungarian first division 5 times. There was further international cup success, including two Mitropa Cup titles in 1929 and 1939, and also the Cup of Nations title in 1930. The team finished in a top three position in every season between 1926 and 1942, and played in 5-cup finals during the 20's and 30's.

Újpest supplied 5 players for the World Cup of 1938, which saw Hungary finish as runners-up. They included György Szűcs, Antal Szalay, István Balogh I, Jenő Vincze, and the rising star of Hungarian football, Gyula Zsengellér. 

The immediate years after World War II saw the second golden era of Újpest, and saw the club win the domestic championship three times in a row. They even managed to supply 9 players to the Hungarian international squad. Players like Ferenc Szusza, Béla Egresi, Sándor Balogh II, István Nyers or Mihály Nagymarosi were setting records of winning 30 consecutive games, and even managing to score 187 goals in one single season.

In 1950 the communist government chose Újpest as the 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 countries "police clubs" were all named Dinamo/Dynamo.) 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 the 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 put down by the Soviets, the Hungarian government - unlike for FTC or MTK - didn't let the club use their old name. This resulted in the name Újpesti Dózsa, which referred both to the district and to the police. After 13 years without a league title, Újpest finally became champions of Hungary in 1959-60, and reached the Cup Winners' Cup semi-final in 1962 with the help of new star, János Göröcs.

1967 marked the start of a new golden era under manager Lajos Baróti. After two runners-up medals, Újpest won the league in 1969 and played in the Inter-Cities Fairs Cup final in the same year (and 6-2 on aggregate against Newcastle United). The team then went on to win an amazing 7 titles in a row. They were champions for each season from 1969 to 1975, setting incredible post-war records like scoring exactly 500 goals in the seven seasons and losing only 4 home matches in 10 seasons.

The club also enjoyed success in the other domestic competition, winning the Hungarian Cup for the first time in 1969, and also in 1970 & 1975. On the international scene, besides the Inter-Cities Faris Cup final, Újpesti Dózsa reached the European Cup quarter-finals in three consecutive years from 1972, making the semi-finals in 1974, where only the eventual winners Bayern Munich put a stop to their campaign. The club was considered one of the best teams in Europe beating such teams as English champions Leeds United in 1969, Spanish champion Valencia CF in 1971, and Scottish champions Glasgow Celtic in 1972. They also beat top Portuguese side Benfica in 1973. 

The 'landmark' of the team - as always for Újpest - was goal scoring. The famous Fazekas - Göröcs - Bene - Dunai II - Zámbó attacking formation, invented and led by manager Lajos Baróti, scored dozens of goals, attracting thousands of football fans both in Hungary and abroad. Bene became 5 times top scorer of Hungary, Dunai II and Fazekas won the Silver boot award for scoring the second most goals in the continent.

After Göröcs, Bene and Dunai left the team, András Törőcsik and László Fekete joined Újpest and they won two more league titles in 1978 and 1979 with former player Pál Várhidi as the head coach. Törőcsik was considered a "magician" by the fans of the club, possessing unbelievable dribbling skills, scoring amazing goals and supplying unexpected assists to team-mates, while Fekete also won the European Silver boot.

With the fall of the communist government and the termination of state sponsorship, came financial problems as well, just like for all other Hungarian football clubs. Professionalism was once again introduced into Hungarian football in 1998, thus the club changed their name again, but this time to the well known Újpest FC.
