The Bosnians or Bosniaks resemble their Servian kinsfolk in both appearance and character.
Herzegovina, where Vukcic offered a desperate resistance, held out until 1483; but apart from the heroic defence of Jajce, the efforts of the Bosnians were feeble and inglorious, many of the Bogomils joining the enemy.
Instead of extending the foreign conquests of their sultan, the Bosnians were hard pressed to defend their own borders.
The Bulgarians, Bosnians and Servians had at different periods invaded and conquered the territories inhabited by them; the Albanians, original natives of their land, were governed by princes of their own.
In Bosnia the persistent attempts of the Magyar princes to root out the stubborn, crazy and poisonous sect of the Bogomils had alienated the originally amicable Bosnians, and in 1353 Louis was compelled to buy the friendship of their Bar Tvrtko by acknowledging him as king of Bosnia.
