A political machine is an unofficial system of a political organization base on patronage, the spoils system, "behind-the-scenes" control, and longstanding political ties within the structure of a representative democracy. Machines sometimes have a boss, and always have a long-term corps of dedicated workers who depend on the patronage generated by government contracts and jobs. Machine politics has existed in many United States cities, especially between about 1875 and 1950, but continuing in some cases down to the present day. It is also common (under the name clientelism or political clientelism) in Latin America, especially in rural areas, and also in some African states and other emerging democracies, like postcommunist Eastern European countries. Japan's Liberal Democratic Party is often cited as another political machine, maintaining power in suburban and rural areas through its control of farm bureaus and road construction agencies.
