The Serbian king Dusan went to war with Stjepan II Kotromanic over Hum and penetrated deep into Bosnia. Only the sudden invasion of the Byzantines to the far south saved Stjepan from Dusan, who fled Bosnia.

1377.

Bosnian banus Stjepan Tvrtko Kotromanic, gathering under his rule not only "small land" Bosnia but also Usora, Hum's area, Travunja, Primorje, Donji Krajevi, Zapadne Strane and Podrinje, has declared himself as the king of "Srblji, Bosnia and Primorje", by which act Bosnia became an independent kingdom and seceded from Croatian-Hungarian state. By making use of political turmoil in the Croatian-Hungarian state--the twenty-five-years's Croatian movement--- king Tvrtko has for a short period around 1390. taken the rule over whole Croatia south from Velebit, except Zadar and Dubrovnik. This traditionally Croatian state survived until 1463., when the Turks have conquered Bosnian kingdom. Elizabeth, the daughter of Bosnian banus Tvrtko Kotromanic and the wife of Croatian-Hungarian king Ludovik Angevin, has ordered to make the silver sarcophagus of St. Simun, a masterwork of Middle-Age Croatian gothic goldsmithery.

Viganj Miloševic deceased. A part of the grave-stone from his grave in Kocerin field nearby Siroki Brijeg is conserved, with the inscription on it written in Bosnian/Croatoan/Western Cyrillic (this alphabet being known as "bosancica"), which states: "+ Va ime oca i sina i svet(a)go d(u)ha. Amin! Se (ovdje) lezo Vig(a)ri Miloševic. Sluzi banu Stipanu, i kralu T(vrt')ku, i kralu Dabisi i kralici Grubi, i krala Ostoju. I u to vrime doide, i svadi se Ostoja kral' s Hercegom i z Bosn(o)m i na Ugre poe Ostoja. To vrime mene Vigna doide koncina i legoh na svom plemenitom pod Kocerinom. I molu vas, ne nastupaite na me! Ja s(a)m bil kako vi (j)este, vi cete biti kako (j)esam ja."
The approximate translation of this inscription would be as follows:
"+ In the name of the Father and the Son and the Holy Spirit. Amen! (Here) lieth Vigari Milosevic. Served banus Stipan, and king Tvrtko and king Dabisa, and queen Gruba, and king Ostoja. And the time came, when king Ostoja was quarelling with the Herzog and with Bosnia, and when Ostoja fetched Ugre. At that time I Vigna came to my end and laid down on my noble Kocerina. I beg you, do not step on me! I was as such as thou art, thou willest be as such as I am."

Duke Hrvoje's autocratic reign incited discontent among many Hungarian and Croatian aristocrats, and especially in Bosnia, where his personal enemies were king Ostoja and Sandalj Hranic. They succeeded in persuading Zigmund finally to proclaim Hrvoje guilty of high treason and he called upon all aristocrats to revolt against Hrvoje and his followers. Abandoned by everyone, Hrvoje asked for help from the Turks.

1415 .
Hrvoje, with his own and Turkish troops, defeated the Hungarian-Slavonian army around Doboj (on the Spreca). After that victory, he became the sole master of western Bosnia, while the rest of the country was, in greater part, under Turkish supreme authority.

In order to defend Croatia and Slavonia from the Venetians and the Turks, Zigmund installed three military camps: a Croatian one towards the Adriatic sea and Dalmatia, a Slavonian one towards Una, and one at Usora, ordering in great detail how many soldiers each camp had to give, and an inventory of noblemen and their property in each district. That system was the beginning of the latter Vojna Krajina (Military Frontier).

1448.

Stjepan Vukcic Kosaca declared himself duke ("herceg"), after which title his estate -- the region from Prijepolje, Pljevlje, Niksic and Boka Kotorska to Omis and Poljice, Livno and upper Vrbas -- was named Hercegovina. As a separate political region, between Turkey and neighbouring Christian states, in reduced measure, Herzegovina has survived till the beginning of 1482., when the Turks conquered the last stronghold Herceg Novi.

Juraj Dragisic, a refugee from Bosnia (Srebrenica), a Franciscan, classic and orientalist, an arbiter in intellectual disputes, a philosopher, theologian and humanist, has published his work "Profecitae solutiones.." in Florence 1497. By this work he stood in defence of Dominican monk Girolamo Savonarola, who died at the stake from heresy 1498. Although Dragisic, as a humanist, philosopher and theologian has had a great reputation, under
pressure he nevertheless has sequestered himself to Dubrovnik; in his own words "compelled by the rage of enemies, and attracted by the love to my fellow-countrymen...to unknown homeland....alien to my brothers and the stranger to the sons of my own mother."
