The Holly King and Oak King are personifications of the winter and summer in various neopagan traditions. The two kings engage in endless "battle" reflecting the seasonal cycles of the year: not only solar light and dark, but also crop renewal and growth. During warm days of Midsummer the Oak King is at the height of his strength; the Holly King regains power at the Autumn equinox, then his strength peaks during Midwinter, at which point the Oak King is reborn, regaining power at the Spring equinox, and perpetuating the succession.
