In 1920 the club renamed "Talleres Football Club", and five years later it promoted to Primera División, the top division of Argentina. The club also acquired the land where its headquarters and sports field are now located. Some years after, the club would adopt the current name, "Club Atlético Talleres".
The 1970 squad promoted to the second division
Talleres merged with Club Atlético Lanús in 1934 to form a competitive team for the Primera División championship. The new club switched to "La Unión Talleres-Lanús" although the merger only lasted a year. Talleres played in Primera until 1938 when the team was relegated to the second division. Talleres has been playing in lower divisions and never returned to Primera since then.
In 1945 Talleres inaugurated a swimming pool and the club increased its social activities (the carnival celebrations amongst them). Likewise other sports were incorporated as sports, such as basketball, water polo, swimming and athletics.
In 1999 the club was declared bankrupt, being closed for a short time. In 2000 Talleres signed an agreement with Club Atlético Vélez Sarsfield which ended in 2003. At the end of 2008 Talleres could revoke the bankruptcy petition.
The club colours (red and white, in vertical stripes) were taken from the Alumni Athletic Club, a legendary team founded in 1893 by a group of students of the Buenos Aires English High School which was dissolved in 1913. Alumni was the most successful team during the first 20 years of Argentine football, having won 10 Primera División titles between 1900 and 1911,[2] when the squad played its last official match versus Club Porteño.[3]
