1999 Rugby World Cup in the context of "Rugby World Cup"

The Millennium Stadium (Welsh: Stadiwm y Mileniwm), known since 2016 as the Principality Stadium (Welsh: Stadiwm Principality) for sponsorship reasons, is the national stadium of Wales. Located in Cardiff, it has a retractable roof and is the home of the Wales national rugby union team; it has also held Wales national football team games. Initially built to host the 1999 Rugby World Cup and replacing the National Stadium, it has gone on to host many other large-scale events, such as the Tsunami Relief Cardiff concert, the Super Special Stage of Wales Rally Great Britain, the Speedway Grand Prix of Great Britain and various concerts. It also hosted FA Cup, League Cup and Football League play-off finals while Wembley Stadium was being redeveloped between 2001 and 2006, as well as football matches during the 2012 Summer Olympics.

The stadium is owned by Millennium Stadium plc, a subsidiary company of the Welsh Rugby Union (WRU). The architects were Bligh Lobb Sports Architecture. The structural engineers were WS Atkins and the building contractor was Laing. The total construction cost of the stadium was £121million, of which the Millennium Commission funded £46 million.

The Wales national rugby union team represents Wales in men's international rugby union. Its governing body, the Welsh Rugby Union (WRU), was established in 1881, the same year that Wales played their first international against England. The team plays its home matches at the Millennium Stadium in Cardiff, which replaced Cardiff Arms Park as the national stadium of Wales in 1999.

Wales has competed annually in the Six Nations Championship (previously the Home Nations Championship and Five Nations Championship) since it was established in 1883. They have won the tournament (and its predecessors) outright 28 times, most recently in 2021. Since the Six Nations was formed in 2000, Wales have won six Six Nations titles, including four Grand Slams, and finished bottom three times. Wales has also participated in every Rugby World Cup since the competition was established in 1987; they finished third in the inaugural tournament and have since made two semi-finals, in 2011 and 2019. Wales were the host nation for the 1999 Rugby World Cup, although matches were also played in England, Scotland, Ireland and France.

The Namibia national rugby union team (nicknamed the Welwitschias) represents Namibia in men's international rugby union competitions. They are a tier-two nation in the World Rugby tier system, and have participated in seven Rugby World Cup competitions since their first appearance in 1999. They are governed by the Namibia Rugby Union.

Namibia has been playing international rugby since the early 1900s. As well as having competed at the World Cup, Namibia competes annually in the Africa Cup. Until independence, players for Namibia were also eligible to represent South Africa, with Namibian-born Springboks including Jan Ellis.
