The 1991 Rugby World Cup was the second edition of the Rugby World Cup, and was jointly hosted by England, Scotland, Wales, Ireland and France: at the time, the five European countries who participated in the Five Nations Championship. This was the first Rugby World Cup to be staged in the northern hemisphere, with England the hosts of the final. Also for the first time, qualifying competitions were introduced as the number of entrants had increased, from 16 nations four years earlier, to 33 countries. The eight quarter-finalists from 1987 qualified automatically with the remaining eight spots contested through qualifiers by 25 countries. This resulted in only one new side qualifying for the tournament, Western Samoa replacing Tonga. The same 16-team pool/knock-out format was used with just minor changes to the points system. South Africa was again not included because of sanctions imposed on the country by the International Rugby Board (IRB), due to the government's apartheid policies.
