Swimming has long been a fundamental skill for humans, evolving from a means of survival into a structured sport. The history of swimming strokes goes back thousands of years, with early techniques used for crossing bodies of water and for military training.
Over time, these strokes were refined into clearer forms, eventually giving rise to the four competitive strokes you know today: freestyle, backstroke, breaststroke, and butterfly.
This article looks at how swimming strokes developed throughout history, their role in various cultures, and how they evolved into modern competitive techniques.
The background of swimming as a sport
Swimming has been an important part of human life for thousands of years, with evidence showing that early humans developed basic swimming techniques for both survival and cultural purposes.
Ancient civilisations such as Egypt, Greece, and Rome documented swimming through murals, statues, and texts, showing how important swimming was in their lives. Over time, swimming developed from a basic skill into a structured activity, and this shaped the swimming techniques you see today.
Swimming in Ancient Civilisations
One of the earliest depictions of swimming dates back to around 10,000 BC, in the form of cave paintings found in the Cave of Swimmers in the Gilf Kebir region of Egypt.
These illustrations show human figures performing movements resembling breaststroke and doggy paddle, indicating that swimming was already recognised as a skill at that time.
In addition, paintings on Egyptian tombs from 2000 BC show swimmers using coordinated hand and leg movements, further confirming that swimming was practised and valued in ancient society.
The Greeks and Romans also greatly valued swimming, making it part of daily life. In ancient Greece, swimming was considered an essential skill and was often taught alongside running and wrestling as part of military and athletic training.
The Greek philosopher Plato even stated that an uneducated person was “one who cannot read or swim,” showing that swimming was considered a fundamental ability.
Public baths and pools were common in Greek and Roman society, where people gathered for recreation, hygiene, and sport.
Roman soldiers were trained to swim across rivers using movements resembling breaststroke, showing how important swimming was in military strategy. The Romans even built artificial pools specifically for swimming training, some large enough to host early forms of swimming competitions.
Swimming as a Survival Skill
Before swimming became a sport, it mainly served as a survival skill. Early humans relied on natural bodies of water for hunting, foraging, and migration, and so they developed techniques to move efficiently through water.
Rivers and lakes were major sources of food, and the ability to swim allowed early humans to catch fish, gather aquatic plants, and travel more effectively. Tribes living near coasts or rivers naturally incorporated swimming into their daily routines, passing this skill down to future generations.
Migration also played a major role in shaping swimming techniques. As humans began spreading across continents, crossing rivers and lakes became essential for survival. Those who could swim had an advantage, as they could cross bodies of water while carrying supplies, and could even help those who could not swim.
In some cases, simple rafts were used alongside swimming techniques to transport goods and people. Strokes such as sidestroke and the basic flutter kick were likely developed during these early crossings, as they allowed for more controlled movement in strong currents.
Trade also helped refine swimming skills. Civilisations engaged in maritime trade and fishing needed to be able to survive should accidents occur at sea.
Historical records mention Phoenician and Viking sailors as highly skilled swimmers, capable of navigating rough waters and rescuing fellow crew members. Practical uses of swimming like these formed the foundation for techniques that were later refined for sport and recreation.
The Development of Specific Swimming Strokes
Swimming strokes have developed significantly over the centuries, from simple survival techniques into refined movements used in competitive sport. Swimmers in ancient times used basic strokes such as breaststroke and sidestroke, which prioritised energy conservation and stability.
Each stroke evolved in response to the need for greater speed, endurance, and technique, and this is what shaped modern swimming as you know it today.
Breaststroke
Breaststroke is one of the oldest recorded swimming strokes, with origins dating back thousands of years. Paintings from ancient Egypt, Greece, and Rome often depict human figures swimming with movements very similar to breaststroke.
Early versions of this stroke used simultaneous arm movements and a frog-like kick, making it well suited for swimming in calm waters. Unlike strokes designed for speed, breaststroke in the past prioritised control and endurance, making it the preferred choice for long-distance swimming.
In the 17th century, breaststroke became one of the first strokes to be documented in a book. In 1696, French author Melchisédech Thévenot described it in his book The Art of Swimming, cementing its position as a recognised technique.
By the time competitive swimming began to develop in the 19th century, breaststroke was already a favoured stroke thanks to its stability and suitability for swimmers of all levels.
Although breaststroke has remained largely unchanged over the centuries, competitive swimming introduced a number of refinements to improve speed and efficiency.
Early swimmers used a technique with the head kept above water, which caused a lot of drag and slowed movement. Over time, swimmers realised that a sleeker body position closer to the water's surface could reduce drag and allow for smoother movement.
In the 1930s, new techniques such as the underwater pullout and dolphin kick emerged, increasing speed and momentum. However, these variations were later regulated to keep competition fair.
Modern breaststroke now includes a coordinated arm pull, a strong kick, and a glide phase designed to maximise efficiency while conserving energy. Competitive swimmers also focus on explosive starts and turns, using underwater techniques to gain an advantage.
Sidestroke and Trudgen
Sidestroke was once highly favoured for its efficiency and ease of breathing, making it a preferred choice for survival and long-distance swimming.
Unlike other strokes that require rhythmic breathing techniques, sidestroke allows you to keep your head above water at all times, giving you a clear view while swimming. This made it especially useful for rescue work, military training, and endurance swimming.
One of the key features of sidestroke is the scissor kick, in which both legs move apart before coming back together to propel the body forward.
The upper arm pulls while the lower arm extends forward, creating a smooth, energy-efficient movement. This technique allowed swimmers to cover long distances without tiring easily, and was essential for soldiers, lifeguards, and rescue teams.
Sidestroke was widely taught in military training programmes, particularly during the 19th and early 20th centuries. Soldiers and sailors used this stroke to cross rivers, help injured comrades, and carry out water rescues.
Although sidestroke is no longer used in competitive swimming, it remains a valuable skill in water safety and survival training.
In the late 19th century, British swimmer John Trudgen introduced a new variation of sidestroke involving an overarm stroke above the water.
During a visit to South America, he observed native swimmers using a technique involving alternating arm movements, rather than the sculling motion used in traditional sidestroke. By adapting this style, Trudgen created what later became known as the Trudgen stroke.
This new style was faster and stronger than the original sidestroke because the over-water arm movement reduced drag and increased propulsion.
The Trudgen technique quickly became popular in competitive swimming, where swimmers were always looking for ways to improve their times. This style later evolved into the front crawl, which is now the main stroke in the freestyle category.
Front Crawl
The front crawl, now known as freestyle, originated from the swimming techniques of indigenous peoples. At first, European swimmers used strokes like the sidestroke and breaststroke, which were slower but offered greater stability.
However, in the 19th century, British swimmer John Trudgen observed South American indigenous people using an overhead circular arm motion with a scissor kick. This technique was far more efficient as it allowed continuous propulsion with minimal drag.
Trudgen introduced this style to Europe, and later Australian swimmers refined it by replacing the scissor kick with a fast flutter kick, further increasing speed and efficiency.
The adoption of the front crawl revolutionised competitive swimming, particularly in the freestyle category. By the early 20th century, this stroke became the dominant style in races, as it proved far faster than the sidestroke and breaststroke. In the 1920s and 1930s, the technique was further refined with a focus on bilateral breathing and improved body rotation, which helped reduce drag and maintain momentum.
The front crawl became the foundation of the freestyle category, in which you are free to choose whichever swimming stroke you use. Its introduction drastically reduced race times, making it the preferred technique in international competitions, including the Olympics.
Backstroke
Backstroke was originally developed as a variation of breaststroke, allowing you to swim efficiently while keeping your face above the water's surface.
Early swimmers discovered that by turning onto their backs and performing arm and leg movements similar to breaststroke, they could reduce fatigue while maintaining a steady swimming rhythm. This method was particularly useful for open water swimming, where visibility and breathing were essential.
Unlike breaststroke, which requires periodic head movement for breathing, backstroke allows uninterrupted breathing, making it a practical alternative for long distance swimming.
By the early 20th century, backstroke was recognised as a competitive stroke, and its original technique was modified to increase speed and reduce drag. Instead of using a frog kick, competitors began using a fast flutter kick similar to that in the front crawl, providing better propulsion.
The arm movement also evolved from a simple paddling motion into an alternating overhead circular motion, allowing you to swim more smoothly and quickly. When backstroke was introduced to the Olympics in 1900, official rules began to be standardised, driving the development of the modern technique used today.
Over time, advances in training methods and technology have significantly improved backstroke performance. High speed cameras and underwater analysis have helped refine body position, movement efficiency, and turning technique.
The introduction of the backstroke flip turn in the 1990s allowed swimmers to maintain momentum when changing direction, helping to significantly cut down race times. In addition, modern swimwear designed for hydrodynamic efficiency has further reduced drag, making your movement through the water smoother.
Today, backstroke is one of the main events in competitive swimming, and athletes continue to push the limits of performance through strength training, technique optimisation, and scientific research.
Butterfly
Butterfly emerged in the 1930s as a variation of breaststroke, when swimmers experimented with new ways to increase speed. Traditionally, breaststroke required both arms to move in a circular motion underwater simultaneously.
However, some swimmers discovered that by lifting both arms out of the water at the same time, they could reduce drag and swim faster.
At first, this modification was still considered part of breaststroke, but as the technique developed, it was eventually recognised as a fundamentally different stroke.
The key difference lies in the introduction of the dolphin kick, in which both of your legs move together in a wave-like motion, replacing the frog kick typically used in breaststroke. This change significantly increased speed, making butterfly the second fastest stroke after freestyle.
When butterfly was officially introduced as its own event at the 1956 Olympics, the technique had already been highly refined, including strong upper body strength, precise timing, and streamlined turns.
Butterfly is known as the most physically demanding swimming stroke, as it requires exceptional strength, coordination, and endurance.
The simultaneous arm recovery and dolphin kick create high resistance, meaning you must generate maximum propulsion with every movement while maintaining rhythm.
Unlike freestyle and backstroke, which allow alternating arm movements, butterfly requires full body engagement, causing fatigue to set in more quickly.
To sustain this stroke over race distances of 50 metres to 200 metres, butterfly swimmers must train intensively to build upper body strength, core stability, and cardiovascular endurance.
Conclusion on the History of Swimming Strokes
The history of swimming strokes is clear evidence of humanity's ability to adapt, innovate, and share knowledge across cultures. What began as a basic survival skill has now evolved into refined techniques that define modern competitive swimming.
From the earliest depictions of breaststroke in ancient Egypt to the swift efficiency of the freestyle you see today, each stroke has undergone major refinement over the centuries through practice, competition, and technological advances.

Frequently asked questions
Do Modern Swimmers Still Use Ancient Swimming Techniques?
Yes, modern swimmers still use elements of ancient swimming techniques, although these have been greatly refined. For example, the breaststroke movement can be traced back to ancient paintings, but the modern version is far faster and more structured due to improved body positioning and movement timing.
In addition, techniques such as sculling, sidestroke, and floating, which were once used for survival, are still used today in lifesaving training and long distance swimming.
How Did Swimming Strokes Influence Military Training in the Past?
Swimming strokes played an important role in military training, particularly for naval forces and amphibious operations. The Romans, Greeks, and even Samurai practised combat techniques in water, using strokes such as breaststroke and sidestroke for quiet, efficient movement.
Today, elite military units such as the Navy SEALs and special forces still rely on energy efficient strokes such as the combat sidestroke for long distance swims and water operations.
Is There a Swimming Stroke That Doesn't Drain Energy but Is Still Effective?
Yes, sidestroke is one of the most energy efficient swimming strokes, making it well suited for long distance swimming and lifesaving. Unlike other strokes that require rapid, repeated arm movements, sidestroke allows you to glide through the water with minimal drag while conserving energy.
Which Swimming Stroke Has Changed the Least Throughout History?
Breaststroke is the stroke that has remained the most consistent from ancient times to today. Egyptian and Roman paintings depict this stroke with movements similar to the modern version.
Although the modern breaststroke is faster, with a more effective arm pull, a smoother glide, and a more directed kick, the basic movement, a frog kick and a simultaneous arm sweep, has remained almost unchanged for centuries.
Why Was Butterfly Originally Part of Breaststroke?
Butterfly was originally developed in the 1930s as a variation of breaststroke, when swimmers discovered that moving their arms above the water's surface could increase speed.
At the time, competitive swimmers were experimenting with various techniques to gain an advantage, and this movement proved to reduce drag and increase propulsion in the water.
