The lottery is a type of gambling in which people purchase chances, called tickets, to win prizes. The prizes are drawn from a pool that contains all the tickets sold. The pool can be a single large prize, or it may contain many smaller ones. The amount of money paid out to winners is often determined by the promoter, who also pays all expenses related to the drawing, including advertising and taxes.

The first recorded lotteries appeared in China between 205 and 187 BC, where they were used to finance public works projects. They were also widely used in Europe from the 15th century on, especially in Flanders and Burgundy. In France, Francis I permitted the establishment of lottery organizations in several cities in the 1500s.

During the 17th century it became customary in most European countries to use lotteries for a wide range of public purposes, such as raising funds for roads and other public uses. They were viewed as a convenient means of avoiding the need for taxation, but they also came under criticism for their role in promoting compulsive gambling.

In colonial America, lotteries were popular for financing both private and public ventures. They were particularly useful in funding construction of churches and college buildings, roads and wharves.
