History.
The Roman fairs were holidays on which there was an intermission of labor and pleadings. In the Roman provinces of Judea and Syria Palaestina, Jewish rabbis prohibited Jews from participating in fairs in certain towns because the religious nature of the fairs contravened the prescribed practice of Judaism.
In the Middle Ages, many fairs developed as short-lasting markets and were very important for long-distance and international trade. Traders travelled, sometimes for many days, to fairs where they could be sure to meet those they needed to buy from or sell to. Fairs were usually tied to special Christian religious events, such as the Saint's day of the local church. Stagshaw, in England, held annual fairs as early as 1293 consisting of the sales of animals. Along with the main fair held on 4 July, the city also hosted smaller fairs throughout the year where certain types of animals were sold, such as one for horses, one for lambs, and one for ewes.
The Kumbh Mela, held every twelve years, at Allahabad, Haridwar, Nashik, and Ujjain is one of the largest fairs in India, where more than 60 million people gathered in January 2001, making it the largest gathering anywhere in the world. "Kumbha" means a pitcher and "Mela" means "fair" in Sanskrit.
In the United States, fairs draw in as many as 150 million people each summer. Children's competitions at an American fair range from breeding small animals to robotics, whilst the organization 4-H has become a traditional association.
