CB Estudiantes Madrid

The club Estudiantes was founded in 1948 by a group of students (the "Estudiantes") of a public preparatory school (the Instituto Ramiro de Maeztu, IRM) in Madrid to form a team to practice sport during the school recesses. Mr. Antonio Magariños, Professor of Latin and head of studies of the high school, was the first president of the club. He held the position until 1964. From 1949 it has played in the maximum category of the Spanish basketball.

By the time when the first Spanish-wide season-long championship was organized in 1955, by the Spanish Basketball Association (FEB), it was one of the six clubs participating in that tournament, as the second best team from the Province of Madrid (the first being Real Madrid. Until 2021, it had always participated in the premier Spanish basketball league along with Real Madrid and Joventut. It was also one of two only Spanish basketball clubs with teams both at the top male and female Spanish championships.

In May 1963, Estudiantes won their first trophy, the Spanish Cup, against Real Madrid. In April 1992, a month after winning his second Spanish Cup against CAI Zaragoza, Estudiantes reached the 1992 EuroLeague Final Four in Istanbul, finishing in 4th place. It was his Annus mirabilis. In March 1999, the team played his only European final, in the 1998–99 Korać Cup, by defeated by FC Barcelona. In January 2000, Estu won his third Spanish Cup against Valencia, the last one until today. In the 2003–04 ACB season, it reached the Spanish ACB League finals, where they could not win against FC Barcelona.

In May 2012, after several irregular seasons, marked by a bad economic situation, Estudiantes was relegated for the first time in its history from the top tier of Spanish basketball, but remained in the league because LEB Oro champion CB 1939 Canarias didn't present the required documentation and money. In May 2016, again, the team was relegated, but remained in the ACB because champion Palencia Baloncesto didn't present the required documentation and money. Finally, after several relatively stable years, the team's relegation was completed during the coronavirus pandemic in May 2021. Since then, Estu remains in LEB Oro, fighting for promotion and returning to the ACB.
