The Maglia Rosa has been the striking symbol worn by the leader of the Giro d’Italia since 1931. In 1946 the organisers decided it was time bring out a second jersey which was to be worn by the ‘leader’ of a separate contest within the Giro. It wasn’t given, as you might expect, to the rider winning the mountains or points classification. The climbers competition has run since 1933 but there was no leaders jersey until 1974 when the Spaniard José Manuel Fuente was the first to wear the green maglia verde (It is now the blue maglia azzurra). He wore it through the whole race so also became the first to win it. The points competition was first run in 1958 then disappeared till 1966 and in 1967 the first maglia rosso (red jersey) was worn by Giorgio Zancanaro and eventually won by the then reigning Tour of Flanders champion Dino Zandegù. (In 1970 the maglia rosso became the maglia ciclamino which was mauve. It went back to red in 2010 but the maglia ciclamino returns this year).
The new jersey which arrived in 1946 was black and it was awarded to the man who was placed last at the Giro d’Italia. The colour of the jersey was chosen as it was a gloomy alternative to the leaders striking pink but there was also a possible political undertone to it. The 1946 race was the first edition since the Second World War. Fascism had been defeated and the fascist uniform, the black shirt, was something that no longer commanded respect, it was to be ridiculed. Those wearing black shirts were no longer the leaders at the top, they were the losers. The race director Vincenzo Torriani was known to have anti-fascist sympathies which may explain the colour but his reason for creating the icon of the black jersey was as much to do with marketing as anything else. Race fans would hang around the stage end for a lot longer to catch a sight of the black jersey coming in, perhaps spending a little money as they did so.
