Another source of the Bulgarian national revival was the Romantic nationalist vision of a people sharing oral traditions and practices. These ideas were stimulated by the work of Johann Gottfried Herder in particular, and were reinforced by Russian Slavophiles and the model Serbian nationalism under the stimulus of scholar-publicists such as Vuk Karadžić. In Bulgaria, the scholar and newspaper editor Lyuben Karavelov played an important role in collecting and publishing oral traditions, and comparing them with the traditions of other Slavic peoples.
