The javelin throw is a track and field event where the javelin, a spear about 2.5 m (8 ft 2 in) in length, is thrown. The javelin thrower gains momentum by running within a predetermined area. Javelin throwing is an event of both the men's decathlon and the women's heptathlon.
The javelin was part of the pentathlon of the Ancient Olympic Games beginning in 708 BC, in two disciplines, distance and target throw. The javelin was thrown with the aid of a thong, called ankyle wound around the middle of the shaft. Athletes would hold the javelin by the thong and when the javelin was released this thong unwound giving the javelin a spiraled flight.
Throwing javelin-like poles into targets was revived in Germany and Sweden in the early 1870s. In Sweden, these poles developed into the modern javelin, and throwing them for distance became a common event there and in Finland in the 1880s. The rules continued to evolve over the next decades; originally, javelins were thrown with no run-up, and holding them by the grip at the center of gravity was not mandatory. Limited run-ups were introduced in the late 1890s, and soon developed into the modern unlimited run-up.
As an Olympic discipline, the javelin throw was introduced in the 1906 Intercalated Games for men, and in the 1932 Summer Olympics for women. It has been included in the decathlon since its introduction in 1912; the all-around, an earlier form of the decathlon held at the 1904 Summer Olympics, did not include the javelin throw.
Of the 69 Olympic medals that have been awarded in the men's javelin, 32 have gone to competitors from Norway, Sweden or Finland. Finland is the only nation to have ever swept the medals at a currently recognized official Olympics, and has done so twice, in 1920 and 1932. (However, Sweden swept the first four places at the 1906 Intercalated Games. Finland's 1920 sweep also featured an additional fourth-place finish. Sweeping the first four places is no longer possible, as only three entrants per country are allowed.) In 1912 Finland also swept the medals in the only appearance in the Olympics of two-handed javelin, an event in which the implement was separately thrown with both the right hand and the left hand and the marks were added together. Quite popular in Finland and Sweden at the time, this event soon faded into obscurity, together with similar variations of the shot and the discus; Sweden's Yngve Häckner, with his total of 114.28 m from 1917, was the last official world record holder.
