The Galadhrim had gone undisturbed since the founding of Lórien in the Second Age until TA 1980, when the Balrog in Khazad-Dûm was freed. Upon this event, many of them fled south to Dol Amroth, while many other Galadhrim sailed over the sea. The Galadhrim that remained lived happily in Lórien until the end of the Third Age. With the departure of Galadriel to the Undying Lands, Lórien was deserted. The remaining Galadhrim went with Celeborn to East Lórien.
Their language was a dialect of Sindarin.
Galadhrim was also the name of the royal Lothlórien army.
