The first person to formulate the modern idea of Pan-Serbism was Dositej Obradović (1739–1811), a writer and thinker who dedicated his writings to the "Slavoserbian people", which he described as "the inhabitants of Serbia, Bosnia, Herzegovina, Montenegro, Dalmatia, Croatia, Syrmium, Banat, and Bačka", and who he regarded as all his "Serbian brethren, regardless of their church and religion". Other proponents of Pan-Serbism included historian Jovan Rajić and politician and lawyer Sava Tekelija, both of whom published works incorporating many of the aforementioned areas under a single umbrella name of "Serbian lands".
