For over five millennia, flickering candles have illuminated the history of humanity with their mystical glow. For many, they have been more than just sources of light and heat against hours of darkness, signifying at times moments of spirituality as well as the remembrance of the deceased. In present-day Korea, candlelight has turned into a symbol of peaceful resistance against social injustice, most notably during the candlelight vigils held for the victims of the 2014 Sewol Ferry disaster and in the protests to impeach President Park Geun-hye that followed in 2016 and 2017.
