Most of what was written about Njegoš during his lifetime was the work of foreigners (officials, scholars or travelers). One of the earliest detailed academic analyses of Njegoš's works was published by Milan Rešetar in 1890. Following the establishment of a common South Slav state in 1918, scholars reinterpreted Njegoš in a Yugoslav light, despite some of his writings being decidedly anti-Muslim and having the potential to alienate Yugoslavia's Muslim citizens, who formed about ten percent of the new country's population. During the interwar period, future Nobel Prize winner Ivo Andrić wrote extensively about Njegoš and his works, and published several papers on the "vladika"'s poetry after the war, as well. Other authors who wrote about Njegoš include Mihailo Lalić, Isidora Sekulić and Anica Savić Rebac.
