Romuva celebrates the Ethnic or Old Religion of the Lithuanians. This religion has very ancient roots and many international links. It was the national and state religion of the Grand Duchy of Lithuania until 1387. It is very closely kindred to Latvian Ethnic Religion known as Dievturi (which means "Bearing God Dievas"). It is also similarly related to the religion of the Old Prussians, and other Baltic peoples.
Followers of Lithuanian Religion chose the name "Romuva" in 1920's. The name honors the Prussian Baltic sanctuary Romuva, which stood in the Prussian land of Nadruva (near Chernahovsk in the Kaliningrad region). http://www.wcer.org/members/europe/Lithuania/
