A Grand Slam champion can mean very different things depending on the era. Before 1968, the majors were amateur events; later, travel, technology, surfaces and the professional tour reshaped who could win them. The clearest way to follow the story is to look at the champions who defined each period—and the conditions they faced.
Here, “Grand Slam” means the singles titles at the Australian Open, French Open, Wimbledon and US Open. Era boundaries are useful guideposts, not official divisions. To keep the recent examples on a consistent footing, the title counts below are historical snapshots through the end of 2024, rather than a complete record of later seasons.
Before the Open Era: champions of the amateur majors
From the first championships through 1967, the major tournaments were officially reserved for amateur players. The best professionals played elsewhere, so the draw did not always include every top player. That makes direct comparisons with later eras complicated: a remarkable title count was built in a different competitive landscape.
Among the men, Australian Roy Emerson won 12 major singles titles, all before the Open Era. American Bill Tilden collected 10, while Australia’s Rod Laver won six as an amateur before adding five more after professionals were admitted. In 1962, Laver won all four majors in one calendar year—the first man to do so since Don Budge in 1938.
The women’s records are just as striking. Helen Wills Moody won 19 singles majors, while Maureen Connolly completed a calendar-year Grand Slam in 1953. Margaret Court won 11 majors before the Open Era and went on to become the only player to complete a calendar-year Grand Slam in the Open Era, in 1970. Her 24 career singles majors remain the highest total in the women’s game.
1968–1979: the Open Era begins
When professionals became eligible for the majors in 1968, the field widened. But the change did not make every tournament equally deep overnight. The Australian Open, in particular, was sometimes skipped by leading players because of its timing and travel demands.
Laver’s 1969 Grand Slam remains the Open Era’s defining early achievement. On the women’s side, Billie Jean King, Court and Chris Evert helped set the standard. Evert’s steady, deep groundstrokes were especially effective on clay: she won the French Open seven times, a record she held until Rafael Nadal surpassed it. Evert finished with 18 singles majors.
The decade also introduced two very different men’s champions. Jimmy Connors brought relentless pace and aggression, while Björn Borg paired exceptional movement with heavy topspin and remarkable composure. Borg won 11 majors before retiring at 26, including five straight Wimbledon titles from 1976 to 1980.
The 1980s: specialists, rivalries and a new power game
The 1980s were shaped by rivalries across distinct playing styles. John McEnroe’s touch and serve-and-volley game contrasted with Ivan Lendl’s punishing baseline attack. Boris Becker and Stefan Edberg became Wimbledon rivals from opposite ends of the net: Becker hit with explosive force, while Edberg relied on crisp, athletic serve-and-volley tennis.
On the women’s side, Martina Navratilova dominated grass and indoor hard courts, winning 18 majors. Her serve, movement and willingness to attack the net made her especially dangerous at Wimbledon, where she won nine singles titles. Evert remained a formidable counterpoint, and their rivalry produced 80 matches—a rare long-running contest between champions with contrasting games.
Steffi Graf arrived near the end of the decade and quickly changed the conversation. In 1988 she won all four majors and Olympic gold, completing the “Golden Slam.” Her forehand, speed and unusually effective combination of power and footwork helped carry her to 22 major singles titles.
The 1990s: Graf, Seles and Sampras
Graf remained the women’s benchmark, but Monica Seles briefly became her fiercest challenger. Seles won eight majors before turning 20, using two-handed strokes on both sides to take the ball early and rush opponents. After she was stabbed during a match in 1993, her absence reshaped the women’s tour; she later returned and added another major.
On the men’s side, Pete Sampras turned serve-and-volley tennis into a major weapon, particularly at Wimbledon. He won 14 majors overall, including seven Wimbledon titles, and held the men’s record until Roger Federer passed it. Andre Agassi offered a contrasting style: a brilliant returner who struck early from the baseline. Agassi’s 1999 French Open win completed his career Grand Slam, meaning he had won all four majors at least once.
Australia’s revival also gathered pace. The tournament’s move to a more convenient January schedule helped attract leading players, and the country produced major champions including Sampras, Agassi and, later, Federer and Djokovic—not all Australians, but all part of the event’s increasingly global field.
The 2000s: Federer, Nadal and Serena Williams
Roger Federer’s rise made the early 2000s look almost effortless. His fluid movement and precise shot-making delivered 15 major titles between 2003 and 2009. Then Rafael Nadal emerged as his most persistent rival. Nadal’s topspin, court coverage and intensity were tailor-made for clay, where he won the French Open in 2005 at age 19 and began a run that would make him the tournament’s defining champion.
Serena Williams was the era’s leading women’s champion. Her powerful serve and first-strike tennis held up across surfaces, and she won 10 major singles titles during the decade. Her 2002 season—when she captured the French Open, Wimbledon and US Open—began a run of dominance that would last well beyond the 2000s.
The 2010s: the Big Three and a changing women’s field
Federer, Nadal and Novak Djokovic shared the men’s spotlight, but their strengths were distinct. Federer’s attacking versatility, Nadal’s left-handed topspin and Djokovic’s elastic defense produced a rivalry era in which tactical adjustments mattered as much as power. Djokovic won 15 majors in the 2010s, including all four in his career by 2016. Nadal added 12 during the decade, with his French Open success remaining exceptional.
Serena won 10 more majors in the 2010s and completed the career Grand Slam long before then. Her 2015 season, with titles at the Australian Open, French Open and Wimbledon, brought her close to another calendar-year sweep. She ultimately finished with 23 major singles titles in the Open Era.
The decade also brought new champions and new storylines. Naomi Osaka won her first major at the 2018 US Open and showed how aggressively a young player could take control of a match. Simona Halep’s movement and counterpunching carried her to two majors, while Ashleigh Barty became Australia’s first women’s singles champion at Roland-Garros in 46 years.
The 2020s through 2024: new champions, familiar records
The 2020s have already introduced a new generation of men’s champions. Carlos Alcaraz won the US Open in 2022, then Wimbledon in 2023 and 2024, before claiming his first French Open in 2024. Jannik Sinner won his first two majors in 2024, taking the Australian Open and US Open. Their success suggests that the men’s game is moving beyond the era defined by Federer, Nadal and Djokovic—though Djokovic remained a major force, winning three majors in 2023.
On the women’s tour, Iga Świątek built a formidable record on clay, winning four French Open titles by 2024 and adding the 2022 US Open. Aryna Sabalenka claimed consecutive Australian Open titles in 2023 and 2024, then won the 2024 US Open. Coco Gauff’s 2023 US Open victory added another young champion to an increasingly open field.

How to compare champions across eras
Raw totals are a useful starting point, not the whole argument. A champion who won before 1968 faced a different eligibility system; an Australian Open title in the 1970s came in a less reliably complete field than one today. Equipment and playing conditions changed, too. Wooden rackets, grass-court schedules and long-distance travel shaped tactics and preparation in ways modern players do not face.
Surface variety matters as well. A career Grand Slam means winning each of the four majors, but it does not mean winning all four in one season. Only a small group has completed the calendar-year version; Laver did it twice, and Court, Steffi Graf and Don Budge also achieved it. The achievement is rare partly because the majors demand different skills: patience and spin on clay, quick adjustment on grass, and adaptability on hard courts.
Frequently Asked Questions
Who has won the most Grand Slam singles titles?
Margaret Court holds the overall women’s singles record with 24 titles, counting her amateur-era and Open Era wins. Novak Djokovic held the men’s record with 24 through 2024. Because the total changes when new majors are won, check the latest season’s results for a current count.
What does the Open Era mean?
The Open Era began in 1968, when major tournaments began admitting professional players alongside amateurs. It created a more complete field, although participation and travel patterns still varied, particularly at the Australian Open in earlier decades.
Is a career Grand Slam the same as a calendar-year Grand Slam?
No. A career Grand Slam means winning each of the four majors at least once during a career. A calendar-year Grand Slam means winning all four in the same calendar year, a much rarer achievement.
Why are champions from different eras difficult to compare?
They faced different rules, equipment, schedules and levels of participation. Title totals show who won most often, but they cannot fully capture the conditions, competition or tactics of each era.
Final Thoughts
Grand Slam history is not a straight line from one record-holder to the next. It is a succession of champions adapting to new surfaces, technology and rivals: Laver’s all-court brilliance, Graf’s speed, Sampras’s serve, Serena’s power, and the contrasting craft of Federer, Nadal and Djokovic. The numbers matter, but the era behind each number is what makes the comparison interesting.
