Swimming is a skill in which a person floats upwards under the buoyancy of water, and through the regular movement of their limbs through buoyancy, the body moves regularly in the water.
In the 1760s, swimming activities were quite active in many parts of the UK. In 1828, Britain built the first indoor swimming pool at George's Pier in Liverpool, and by the 1830s, this type of swimming pool had emerged in major cities in England. In 1837, the first swimming organization was established in London, England, and the earliest swimming competition in the UK was also held. In 1896, swimming was listed as an Olympic competition. 
The highest organization for swimming is the International Swimming Federation, headquartered in Lausanne, Switzerland. Founded in 1908 at the initiative of the Swimming Association of Belgium, Denmark, Finland, France, Germany, the United Kingdom, Hungary, and Sweden.
