Born in Sozopol to a family of Bulgarian refugees from Eastern Thrace (now part of Turkey), he was given access to the Vatican Secret Archives in the 1980s, regarded as a great achievement considered the political situation of the time.

As the director of the National Historical Museum, he had an indirect conflict in 1997–1998 with the President Petar Stoyanov regarding whether to return the Istoriya Slavyanobolgarskaya rough copy to the Zograf Monastery or leave it in Bulgaria.

[2] Dimitrov is the author of 30 treatises and over 250 articles and papers in the sphere of his research, as well as several books (including The Ten Lies of Macedonism and Twelve Myths in Bulgarian History).

He has specialized in palaeography in Paris and also hosts the patriotic history-related Pamet Balgarska (Bulgarian Memory) show on Kanal 1.
