Curfew is a restriction of movement at certain times (usually valid from 22 pm to 6 am). Is introduced by the government in connection with dangerous situation such as riots, natural disaster or threat to national security. Unfortunately, curfew is introduced by totalitarian governments to suppress peaceful protests or resistance movement. During curfew it is forbidden to being on the street. Everywhere are arranged police patrols. If someone breaks the limitation, he will be arrested and sentenced to prison. In Poland last curfew was in force during last martial law. It was directed against “Solidarność” by Polish government at the behest of Moscow. This led to many bloody clashes on the streets. Finally defeated the rebels and overthrow the Communist government.
