Nicolae Densusianu (1846-1911) was a Romanian ethnologist and folklorist, although he was born in Transylvania, at the time part of the Austro-Hungarian Empire. He claimed that ancient Dacia had been the centre of a widespread Pelasgian Empire. His major work, published posthumously, Prehistoric Dacia, includes the suggestion that Atlantis had been located in Dacia, now Romania. The text of this extensive book, in English, is available in its entirety on the Internet.
His excessive nationalism, popular during the communist regime, is now deemed unacceptable and his work discredited.
Densusianu’s work has also been recently echoed in two books by the Serbian historian, Ranko Jakovljevic, although he moves the focus further west from Romania to his own native Serbia.
