Ruin of Doriath

Doriath, the ancient Elven realm of Thingol and Melian, was ultimately destroyed by the Sons of Fëanor. After the Dwarves had sacked Menegroth and were slain in Ossiriand by the Laiquendi, Dior and his wife, Nimloth, returned to Doriath to rule. Not long after, Beren and Lúthien died once more, and the Silmaril came to Dior. When the Sons of Fëanor learned this, they sent Curufin as messenger for regain the Silmaril, but Dior refused. So they assaulted Menegroth and killed Dior Eluchíl and his wife, and their two sons. Although three of Fëanor's sons died also, Doriath was destroyed forever.
