A candlelight vigil or candlelit vigil or candlelight service is an assembly of people carrying candles, held after sunset in order to pray, show support for a specific cause, or remember the dead, in which case, the event is often called a candlelight memorial. Such events may be held to protest the suffering of some marginalized group of people. A large candlelight vigil may have invited speakers with a public address system and may be covered by local or national media. Speakers give their speech at the beginning of the vigil to explain why they are holding a vigil and what it represents. Vigils with a religious purpose often contain prayer and fasting. On Christmas Eve and Easter Eve, many churches hold a candlelight vigil service.
