Historically, lottery games were used in the United Kingdom to raise money for local government and public works projects. One of the first examples was a game called “keno” that originated in China during the Han dynasty from 205 to 187 BC. It was an extremely popular game in the city of Nanjing and is believed to have helped finance major projects such as the Great Wall.

European lotteries began in the 15th century with towns and cities raising money to fortify defenses and help the poor. Francis I of France introduced the first French lotteries in or around 1505. These were public lotteries for the Paris municipality and private ones for religious orders.

In colonial America, lotteries were a popular means of financing both private and public ventures. These included roads, canals and bridges as well as colleges, churches and libraries. They were also used to fund military fortifications and the American Expedition against Canada in 1755. During the French and Indian Wars, colonies raised money through lotteries to pay for their militias.

Today, lotteries are an integral part of state governments. While critics of the games focus on the problem of compulsive gambling and alleged regressive impact on lower-income groups, proponents argue that lotteries provide an alternative source of revenue for states. This is especially important in the immediate post-World War II period, when many states sought to expand their array of social safety nets.

However, lotteries have a long history of evolving with little or no public oversight. This is largely because the process of establishing a lottery is often piecemeal and incremental, with authority and pressures being divided between legislative and executive branches. Moreover, once a lottery is established, it is difficult to change the fundamental policies that govern it. As a result, few, if any, states have a coherent “gambling policy” or “lottery policy.”
