(You may be looking for the Unnamed king (Snow White and the Huntsman)) Edit
The Huntsman: Winter's War Edit
Little is known about him, save for the fact he was seduced by Ravenna, with the king eventually marrying her and making her his queen. Ravenna then used magic to secretly kill him - she is shown touching the king chess piece in chess set, which causes the real king to rapidly bleed to death. He body is shown laid out before his court, with Ravenna assuming control of his kingdom after his death. The rest of the court (save for Ravenna's sister, Freya) are apparently unaware that the king was murdered, no doubt believing he died of some illness. It can be assumed he had no children or other heirs, as Ravenna, as his widow, automatically assumed the throne upon his death.
