When T71 celebrated its 50 years in 2021, it was more than just 50 years "existence". The roots of T71 go back to 1954 at which time, at the initiative of the local CAD (track & field), some basketball fans founded a basketball section. In 1959, the basketball section separates from the CAD and joins the HB Dudelange (handball) club. In 1968, the basketball section becomes an independent entity within the HBD organization.

The T71 mens team has achieved 13 Championship wins and 12 Cup wins and the ladies team won 4 Championships and 3 Cups.
