Actually. the drawves killed Thingol, the elven king, because he wanted their necklace, the Nauglamir, to hold the Silmaril he had gotten from Beren's quest. This necklace was among the greatest drawven treasures, as was the Silmaril one of the greatest treasures among elven-kind. This is, I am pretty sure, one of the main reasons, if not the main reason, that these races were enemies for so long.
