A curfew is an order specifying a time during which certain regulations apply.
The word "curfew" comes from the French phrase "couvre-feu", which means "fire cover". It was later adopted into Middle English as "curfeu", which later became the modern "curfew". Its original meaning refers to a law made by William The Conqueror that all lights and fires should be covered at the ringing of an eight o'clock bell to prevent the spread of destructive fire within communities in timber buildings.
On 28 January 2011, and following the collapse of the police system, President Hosni Mubarak declared a country-wide military enforced curfew. However, it was ignored by demonstrators who continued their sit-in in Tahrir Square. Concerned residents formed neighborhood vigilante groups to defend their communities against looters and the newly escaped prisoners.
On the second anniversary of the revolution, January 2013, a wave of demonstrations swept the country against President Mohamed Morsi who declared a curfew in Port Said, Ismaïlia, and Suez, three cities where deadly street clashes had occurred. In defiance, the locals took to the streets during the curfew, organizing football tournaments and street festivals, prohibiting police and military forces from enforcing the curfew.
Under Iceland's Child Protection Act (no. 80/2002 Art. 92), children aged 12 and under may not be outdoors after 20:00 (8:00 p.m.) unless accompanied by an adult. Children aged 13 to 16 may not be outdoors after 22:00 (10:00 p.m.), unless on their way home from a recognized event organized by a school, sports organization or youth club. During the period 1 May to 1 September, children may be outdoors for two hours longer.
Children and teenagers that break curfew are taken to the local police station and police officers inform their parents to get them. The age limits stated here shall be based upon year of birth, not date of birth. If a parent cannot be reached, the child or teenager is taken to a shelter.
The United Kingdom's 2003 Anti-Social Behaviour Act created zones that allow police from 9 PM to 6 AM to hold and escort home unaccompanied minors under the age of 16, whether badly behaved or not. Although hailed as a success, the High Court ruled in one particular case that the law did not give the police a power of arrest, and officers could not force someone to come with them. On appeal the court of appeal held that the act gave police powers to escort minors home only if they are involved in, or at risk from, actual or imminently anticipated bad behaviour.
