Estrela was founded on the 22nd of January 1932 by a group of seven students from Amadora who shared a passion for football. According to Júlio da Conceição, while looking at the stars in the sky he came up with the idea to the name of the club, which was accepted by all of the founders. The club played their first match against Palmense, from Palma de Baixo, Estrela won by 2-1, curious was the fact that the Estrela players walked to the opponent's stadium, as a warm-up for the match. Registered only in 1941, in 37 years Estrela climbed through the lower leagues, until in 1978 when they were promoted to the 3rd National Division. In the 1988/89 season Estrela made it to the Primeira Ligafor the first time in their history. Their highest point in history is the winning the 1989/90 Taça de Portugal, under the command of João Alves, defeating Farense in the final by 2-0, after drawing 1-1 in the first match. With the victory in the cup, they guaranteed their place in the UEFA Cup Winners' Cup. In the 1st round Estrela Eliminated the Swiss club Neuchâtel Xamax, after drawing in Amadora 1-1, in the 2nd leg in Neuchâtel they drew 1-1 once again, it ended with Estrela winning 4-3 on penalties, a victory celebrated by the thousands of Portuguese emigrants in Switzerland in the stadium and who outnumbered the Swiss fans. In the 2nd round Estrela faced RFC Liége, In the first leg Estrela was defeated 2-0, in the second leg Estrela defeated the Belgian team 1-0 in the 2nd leg, however that one goal wasn't enough and Estrela's European Cup adventure came to an end. The best result Estrela has achieved in the Primeira Liga was 7th place in the 1997/98 season. In the 2008/2009 season, although they managed to stay out of the relegation zone, staying in a comfortable 11th place, they were relegated instead of Belenenses, due to financial reasons. This season was the beginning of the serious financial crisis at the tricolor club. Debts to suppliers, employees, players, tax authorities, social security, etc. At this time, the Professional Players Union was still supporting the club with 1 month's salary, which was not enough to save the. They were automatically relegated to the 3rd tier of Portuguese football, and they were barred from participating in any professional competitions. In the 2009/2010 season, Estrela da Amadora started with coach António Veloso. The results were not as expected and shortly after 2 weeks, their manager was sacked, being replaced by Jorge Paixão, a coach who was used to coaching smaller clubs. In the 1st round of the Taça de Portugal that year, Estrela da Amadora eliminated Mafra, but was disqualified and Mafra was awarded the victory, as Estrela had not paid the players' registration fees to the Portuguese Football Federation. Estrela was going through their worst phase of its existence. They mainly relied on their youth players and players on loan. Starting in the 3rd week, the results of Jorge Paixão started coming in, reaching the top of the standings, winning, 4-1 against Atlético Clube de Portugal. But unfortunately their serious financial situation continued. Overdue wages, workers' strikes, lack of medical treatment, maintenance, buses, etc. The players' striked threating to terminate their contracts, starting a serious decline in the table. Estrela da Amadora finished the season in 10th place, with the majority of their points being won in the 1st half of the season. On September 29, 2009, the Court of Sintra declared the club insolvent. Debts exceeded 11.5 million euros. Former members, coaches and chairmen point out the appropriation of the club for personal gain and the poor management of the last decade as the great evil that the club suffered. Estrela played their last football match on May 2, 2010, in the second division, south zone. Estrela da Amadora lost 0-1 against Real Massamá. In 2010 the club folded due to financial problems. The club was unable to restart as a SAD in the 2nd district division or participate in the 2nd division. A new club, Clube Desportivo Estrela was founded in 2011 to keep their youth teams and other sports, and continue the history and legacy of Estrela da Amadora. In 2018, CF Estrela created a main football team. In 2020, CF Estrela merged with Sintra Football Club to form CF Estrela da Amadora, SAD with the same history as the old Estrela da Amadora.
