It is the oldest and most important of all the international events organized by the FIVB and must not be confused with the World Cup, World Grand Champions Cup, or the World League/World Grand Prix.

The history of the World Championship goes back to the beginnings of volleyball as a professional, high level sport. One of the first concrete measures taken by the FIVB after its foundation in 1947 was the establishment of an international competition involving teams from more than one continent. In 1949, the first edition was played in Prague, Czechoslovakia. At that point, the tournament was men's only and still restricted to Europe.

Three years later, a women's version was introduced; the events were synchronized and expanded to include nations from Asia, and began to be held in 4-year cycles. By the following edition, there were also teams from South, Central and North America.

Since volleyball was to be added to the Olympic Program in 1964, the 4-cycles were advanced in 2 years after the fourth edition (1960), so that the World Championship may alternate with the Summer Olympics. As of 1970, teams from Africa also took part in the competition, and the original goal of having members from all five continental confederations in the games was achieved.

The number of teams involved in the games has changed significantly over the years. Following volleyball's increase in popularity, they raised steadily to over 20 in the 1970s and part of the 1980s, were then cut short to 16 in the 1990s, and finally set up in 24 after 2002. Today, the World Championship is the most comprehensive of all events organized by the FIVB, and arguably the second most important, surpassed in prestige only by the Olympic Games.

Until 1974, the host nation of the tournament organized both the men's and the women's events, with the single exception of the 1966/1967 games, which took place in different years. Russian National Volleyball Team is the most successful team in both men and women with 13 times winning (6 for men and 7 for women).
