The Thomas Cup (men) and Uber Cup (women) are badminton's world team championships, where nations — not individuals — compete for the sport's most coveted team trophies. This guide explains their history (the Thomas Cup from 1948–49, the Uber Cup from 1956–57), how the tie format works, why Indonesia and China dominate the honours, and how these cups differ from the mixed-team Sudirman Cup — with the dates checked against the BWF.
