Other events
The 1891 British Lions tour to South Africa is the first British Isles tour of South Africa and only the second overseas tour conducted by a joint British team. Between 9 July and 7 September, the team plays 20 games, including three Tests against the South Africa national rugby union team. The British Isles wins all 20 matches including the three Tests. Although not named as such at the time, the tour is retrospectively recognised as a British Lions tour.
Tennis
Events
Inaugural French championship is held as the Championat de France International de Tennis. Initially, only the men's singles is contested; the women's singles will begin in 1897. Until 1924, the tournament is open only to tennis players who are licensed in France but, ironically, the inaugural tournament is won by an Englishman, H Briggs, who defeats French player P Baigneres in the final. Briggs is a British resident living in Paris.
