A free party is a party "free" from the restrictions of the legal club scene, similar to the free festival movement. It typically involves a sound system playing electronic dance music from late at night until the time when the organisers decide to go home. A free party can be composed of just one system or of many and if the party becomes a festival, it becomes a teknival. The parties can be thought of as autonomous zones where all the people present create and enforce the rules. This typically means that drugs are readily available and noise levels are usually illegally high. The word free in this context is used both to describe the entry fee and the lack of restrictions and law enforcement.
Motivations for organisers range from political protest to simply wanting to have fun. An example of free parties as political protest was their prominence during the M11 link road protest. At most parties no money is asked for entrance since the aim is not to make profit. However at some (most often indoor) events it is requested at the door to make a donation to cover costs. Typically organisers make little profit or make a loss setting them up. The term free party is used more widely in Europe than in the USA. In Canada and some parts of Europe they are also referred to as Freetekno parties. A free party might have once been described as a rave, and the origins of the two are similar. Since the birth of nightclubs in town centres in Europe the use of the word rave had largely fallen out of fashion, however in recent times it is increasingly being used again.
The term squat party defines the free parties with secret indoor locations. The address is obtained on the day of the event personally from organizers as the buildings are squatted. The parties often last over 24 hours.
After the emergence of the Acid House parties in the late 1980s up to 4,000 people were known to attend a rave. These events happened almost every weekend. The noise and disturbance of thousands of people appearing at parties in rural locations, such as Genesis '88, caused outrage in the national media. The British government made the fine for holding an illegal party £20,000 and six months in prison.
