Early Olympic Games allowed for individuals in a team to be from different nations. The International Olympic Committee (IOC) now groups their results together under the mixed team designation. Until 2024 IOC used code ZZX and since 2024 code XXB for designating mixed teams. During the 1900 Summer Olympics, several teams comprising international members won six medals. Until 2024 the IOC attributed to mixed teams 13 more medals, however, since 2024 these medals were reallocated to the particular countries.
