This is a flag of the Tsardom of Voyislavia. It's name is a made of two words: vojnik (soldier) + slava (glory), and it deserved it because of many heroes who were born in this land.
It is formed on the territories of nowadays Albania, Macedonia, and Montenegro. This country is neighbor with Serbia, Greece, Bulgaria, Croatia, Bosnia and the Northern Hellada [fictional country formed on the southern part of Macedonia]. With the most of the neighbors it has good relationships, except of Bulgaria, who wants an eastern part of a former Macedonia. Croatia and Bosnia have imposed sanctions to the Voyislavia because this country closed the borders, making Croatian and Bosnian trade with Greece and Middle East impossible. That was an answer for open Bosnian and Croatian support of rebellion in Voyislavia.
The main social system is monarchy, and the Tzar is from the famous family of Stefan Dušan VII Orlović, hero from the last war between Voyislavia and Albanian Republic. Recently Voyislavian king considered the establishment of democracy.
The main currency is Dinar, same currency as Serbia use, making it more stable than in 2016, where it nearly devalued on European markets.
Military is strong, but defensive. The Voyislavian Army is consisted of Voyislavia Royal Navy, Voyislavia Royal Airforce and Ground forces. The most weapons are Serbian and Russian manufactured, but with NATO standard small caliber weapons.
Population: around 17 000 000 people [census from 2016: 14 762 054]
There is the 80% of Slavic population. 70,4% are Orthodox Christians, 12,9% Muslims, 11,2% Catholics and rest are various religions.
Official languages: Serbian, Greek, Macedonian, Bulgarian.
