Rugby Union in : The tackle

South Africa, with four (1995, 2007, 2019, 2023) — the only team to win four Rugby School, England, in the 1820s-1840s; the Rugby Football Union codified the laws in 1871 15 a side over two 40-minute halves on a pitch up to 100 m by 70 m, plus in-goal areas What grips people is the collision of brute force and fine strategy inside the same phase. A rolling maul grinding towards the line is settled by leverage and lung capacity; a backline strike move a moment later is settled by timing and sleight of hand. Rugby rewards a 130-kilogram prop and a 75-kilogram winger equally, giving almost any body type a position, and its culture prizes deference to the referee — addressed as 'sir' — and the post-match handshake between opponents. Territory is the game's currency: sides kick for position, defend their own 22, and strangle opponents through relentless pressure as often as they score.

What makes rugby singular is the permanent, legal fight for possession. Unlike most invasion games, the defending side can win the ball back at almost every tackle, scrum and lineout, so possession is never safe and momentum swings on a single turnover. The oval ball bounces unpredictably, turning kicks into lotteries; the offside line, running across the pitch at each breakdown, forces attackers to build through phases rather than simply pass forward. The sport stayed rigidly amateur until 1995, when it turned professional almost overnight, and that late transition still shapes its finances, its global map, and its fierce present-day argument over player welfare and head injury.

The object of rugby union is to score more points than the opposition across eighty minutes by carrying, passing or kicking an oval ball over the opponents' goal line and grounding it for a try, then adding points by kicking the ball between the posts and above the crossbar. Two teams of fifteen contest a pitch up to 100 metres long between the goal lines, with an in-goal area beyond each, and up to 70 metres wide. Play flows almost continuously, and the ball may travel forward only by kicking or running — never by a forward pass or a knock-on.
