The Kingdom of Epirus was formed after the death of the Despotate of Epirus' first monarch, Michael I Komnenos Doukas. He died of a heart attack. A brief civil war occurred before a new monarch rose to the throne The new monarch was Claudian II Chrysós, who was a member of the Chrysós royal house. Chrysós roughly means gold in greek.
During the 1220s they faced their first war with the Latin empire. After a series of victories in Macedonia Epirus gained huge amounts of land from the Latin empire, weakening it so that the Empire of Nicaea could take it in one sweeping blow.
In 1234 the Bulgars north of Epirus invaded the newly acquired territory and pushed into the Epirian heartland and besieged their capital. The Epirians called on the Nicaeans for help but they refused to heed the call, thus igniting a hatred that would fuel Epirian expansion. In 1240 the Bulgars were caught flat-footed when they were invaded by the Hungarians and they called off the siege. The Epirians took advantage of the Bulgars' weakness and they invaded and took some land away from the Bulgars, the Hungarians took most of the Bulgarian land.
By the 1250s Epirus had established a proper tax system which kickstarted their economy and they started to train native Epirian soldiers. On March 20th of 1257 Claudian II Chrysós passed away and his son Claudian III Chrysós succeeded him.
In 1261 the Nicaeans captured Constantinople and restored the Byzantine Empire, leaving the Latin Empire crippled. By this point the Latin Empire only held a few territories in the balkans and Epirus finished the Latin Empire in a quick war.
The rest of the 1200s were peaceful and the Epirians used this time to grow and expand their cities, commissioning new buildings and building projects in Arta.
The 1300s started strong for both Byzantium and Epirus but they both faced huge amounts of trouble in the 14th century.
In 1311 a civil war broke out after Claudian II Chrysós "lost" son returned to Arta and claimed the throne and his he fought Claudian III for control of Epirus. This devastating civil war would end on July 20th, 1317 when Claudian defeated his brother Julius and locked him away.
Only a few years after the devastating civil war in 1325, Byzantium under Andronikos II Palaiologos attacked Epirus in the a war that lasted well beyond Andronikos' death and continued into his sons rule.
In 1329 the First Epirian-Byzantine War ended.
In 1338 the Serbians declared war against both the Epirians and the Byzantine, hoping to gain some more land and they expected both Epirus and Byzantium to be exhausted by war, which they both were to an extent. The Serbians had some initial success against Epirus but they were turned away by the great Epirian general: John II Taktikós. He helped defend against most of the Serbian attacks and sent them back to their homeland.
In 1354 an earthquake devastated Gallipolis, which allowed the Ottoman Turks to migrate into the Balkans and allowed them to set their sights on Europe. They declared war against Epirus and attempted to invade Epirian heartland but they failed at doing that, but they did succeed in taking both Athens and Morea.
In the 1360s the Ottomans took over huge amounts of territory in Thrace, taking Serbian and Byzantine settlements.
In 1361 Claudian III died. His eldest son Claudian IV rose to the throne.
In 1369 the Ottomans took Adrianople which worried Claudian IV and he strengthened the defences in Epirian cities.
In 1380 Arta had grown in population and city size, making it one of the most developed cities in the eastern med.
In 1382 the Ottomans attacked all of the balkan states including Epirus and they won for the most part, they defeated Bulgaria but they could not defeat Epirus.
In 1393 John III, Claudian IV younger brother died of an arrow to the chest.
In 1395 the Ottoman-Balkan War ended.
The 1400s was a very important century for Epirus, in this century it found it's place in the world and had a stable heartland which was needed to repel the Ottoman turks. The fall of Byzantium only weakened Epirus because it was the only thing blocking the Ottomans from Europe.
In 1410 Claudian IV dies, his only son Claudian V rose to the throne.
In 1435 the Ottomans declare war starting the second Ottoman-Epirian War.
In 1444 the war ends
In 1450 Claudian V dies and his son Claudian VI succeeded him.
