Nicolae Iorga (sometimes called Neculai Iorga, Nicolas Jorga, Nicolai Jorga or Nicola Jorga, born Nicu N. Iorga; January 17, 1871 – November 27, 1940) was a Romanian historian, politician, literary critic, memoirist, poet and playwright.
Co-founder (in 1910) of the Democratic Nationalist Party (PND), he served as a member of Parliament, President of the Deputies Assembly and Senate, cabinet minister and briefly (1931–32) as Prime Minister. A child prodigy, polymath and polyglot, Iorga produced an unusually large body of scholarly works, consecrating his international reputation as a medievalist, Byzantinist, Latinist, Slavist, art historian and philosopher of history.
Holding teaching positions at the University of Bucharest, the University of Paris and several other academic institutions, Iorga was founder of the International Congress of Byzantine Studies and the Institute of South-East European Studies (ISSEE). His activity also included the transformation of Vălenii de Munte town into a cultural and academic center.
