Real Madrid Club de Fútbol (meaning Royal Madrid Football Club), commonly referred to as Real Madrid, is a Spanish professional football club based in Madrid. Founded on 6 March 1902 as Madrid Football Club, the club has traditionally worn a white home kit since inception. The word real is Spanish for "royal" and was bestowed to the club by King Alfonso XIII in 1920 together with the royal crown in the emblem. The team has played its home matches in the 81,044-capacity Santiago Bernabéu Stadium in downtown Madrid since 1947. Unlike most European sporting entities, Real Madrid's members (socios) have owned and operated the club throughout its history. The club was estimated to be worth €3.8 billion ($4.2 billion) in 2019, and it was the second highest-earning football club in the world, with an annual revenue of €757,3 million in 2019. The club is one of the most widely supported teams in the world. Real Madrid is one of three founding members of La Liga that have never been relegated from the top division since its inception in 1929, along with Athletic Bilbao and Barcelona. The club holds many long-standing rivalries, most notably El Clásico with Barcelona and El Derbi with Atlético Madrid. Real Madrid established itself as a major force in both Spanish and European football during the 1950s, winning five consecutive European Cups and reaching the final seven times. This success was replicated in the league, which the club won five times in the space of seven years. This team, which consisted of players such as Alfredo Di Stéfano, Ferenc Puskás, Francisco Gento, and Raymond Kopa, is considered by some in the sport to be the greatest team of all time. In domestic football, the club has won 65 trophies; a record 33 La Liga titles, 19 Copa del Rey, 11 Supercopa de España, a Copa Eva Duarte, and a Copa de la Liga. In European and worldwide competitions, the club has won a record 26 trophies; a record 13 European Cup/UEFA Champions League titles, two UEFA Cups and four UEFA Super Cups. In international football, they have achieved a record seven club world championships. Real Madrid was recognised as the FIFA Club of the 20th Century on 11 December 2000, and received the FIFA Centennial Order of Merit on 20 May 2004. The club was also awarded Best European Club of the 20th Century by the IFFHS on 11 May 2010. In June 2017, the team succeeded in becoming the first club to win back to back Champions Leagues, then made it three in a row in May 2018, extending their lead atop the UEFA club rankings.

Tennis is a racket sport that can be played individually against a single opponent (singles) or between two teams of two players each (doubles). Each player uses a tennis racket that is strung with cord to strike a hollow rubber ball covered with felt over or around a net and into the opponent's court. The object of the game is to maneuver the ball in such a way that the opponent is not able to play a valid return. The player who is unable to return the ball will not gain a point, while the opposite player will. Tennis is an Olympic sport and is played at all levels of society and at all ages. The sport can be played by anyone who can hold a racket, including wheelchair users. The modern game of tennis originated in Birmingham, England, in the late 19th century as lawn tennis. It had close connections both to various field (lawn) games such as croquet and bowls as well as to the older racket sport today called real tennis. During most of the 19th century, in fact, the term tennis referred to real tennis, not lawn tennis. The rules of modern tennis have changed little since the 1890s. Two exceptions are that from 1908 to 1961 the server had to keep one foot on the ground at all times, and the adoption of the tiebreak in the 1970s. A recent addition to professional tennis has been the adoption of electronic review technology coupled with a point-challenge system, which allows a player to contest the line call of a point, a system known as Hawk-Eye. Tennis is played by millions of recreational players and is also a popular worldwide spectator sport. The four Grand Slam tournaments (also referred to as the Majors) are especially popular: the Australian Open played on hard courts, the French Open played on red clay courts, Wimbledon played on grass courts, and the US Open also played on hard courts.

Football is a family of team sports that involve, to varying degrees, kicking a ball to score a goal. Unqualified, the word football normally means the form of football that is the most popular where the word is used. Sports commonly called football include association football (known as soccer in some countries); gridiron football (specifically American football or Canadian football); Australian rules football; rugby football (either rugby league or rugby union); and Gaelic football. These various forms of football are known as football codes. There are a number of references to traditional, ancient, or prehistoric ball games played in many different parts of the world. Contemporary codes of football can be traced back to the codification of these games at English public schools during the 19th century. The expansion of the British Empire allowed these rules of football to spread to areas of British influence outside the directly controlled Empire. By the end of the 19th century, distinct regional codes were already developing: Gaelic football, for example, deliberately incorporated the rules of local traditional football games in order to maintain their heritage. In 1888, The Football League was founded in England, becoming the first of many professional football competitions. During the 20th century, several of the various kinds of football grew to become some of the most popular team sports in the world.

Golf is a club-and-ball sport in which players use various clubs to hit balls into a series of holes on a course in as few strokes as possible. Golf, unlike most ball games, cannot and does not utilize a standardized playing area, and coping with the varied terrains encountered on different courses is a key part of the game. The game at the usual level is played on a course with an arranged progression of 18 holes, though recreational courses can be smaller, often having nine holes. Each hole on the course must contain a tee box to start from, and a putting green containing the actual hole or cup in diameter. There are other standard forms of terrain in between, such as the fairway, rough (long grass), bunkers (or "sand traps"), and various hazards (water, rocks) but each hole on a course is unique in its specific layout and arrangement. Golf is played for the lowest number of strokes by an individual, known as stroke play, or the lowest score on the most individual holes in a complete round by an individual or team, known as match play. Stroke play is the most commonly seen format at all levels, but most especially at the elite level. The modern game of golf originated in 15th century Scotland. The 18-hole round was created at the Old Course at St Andrews in 1764. Golf's first major, and the world's oldest tournament in existence, is The Open Championship, also known as the British Open, which was first played in 1860 in Ayrshire, Scotland. This is one of the four major championships in men's professional golf, the other three being played in the United States: The Masters, the U.S. Open, and the PGA Championship.
