Since I'm still a bit mixed up with the current PoW canon, I'll just edit it to fit both Ducky's application (partly) and the lore.
Nation: Republic of Slovene-Croatia
Leader: Janez Dvornik
History: Similar to many Balkan nations at the time, Slovenia and Croatia were occupied by Austria-Hungary before and during the Great War; in this time, the two countries were about to face the winds of change. The Balkan countries were unfortunately affected by the Great War, with battles continuously occurring in their country, often causing the destruction of many cities and loss of lives as some were conscripted by their dominating country. Later, in the midst of the Great War in 1922, it seemed that the Slovenes and Croats, like several other ethnic groups part of the former Austria-Hungary Empire, was caught in confusion and uncertainty as Hungary split from Austria and the Austria-Hungary Empire was dissolved.
For the remainder of the Great War and the years after that, Slovenia and Croatia remained as part of the Austria, despite Slovenia and Croatia's hopes of independence after the Great War. Their pleas were refused, and while Slovenia and Croatia were seen as an autonomous region, it was vigorously kept in place behind Austria using it's military force. Austria had its own problems, however, as after the Great War, Austria was in ruins, with her economy collapsing from war debts. Currency rapidly decreased in value, making even basic goods difficult to purchase.
This economic crisis affect Slovenia and Croatia as well, as the Austrian economy largely sustained Slovenia and Croatia. Many suffered from unemployment and possible hunger. While the Austrian government attempted to establish economic plans to reemploy people and restore the economy, the government was weak and oppressed the zones of Slovenia and Croatia, which planted the seeds of hatred against the Austrian government inside the minds of the Slovenes and Croats, along with other ethnic minorities.
Slovenia and Croatia remained part of Austria until the 1970s; the Slovenes and Croats held their thoughts of revolution temporarily as they focused on rebuilding themselves from the ashes of the Great War. After 1939, Austria, as well as Slovenia and Croatia, had restored themselves to their pre-war economic state. Despite these efforts, Austria still lagged behind in the world as a diminished power. Slovenia and Croatia watched as world changed with new borders being drawn and new countries being formed.
Eventually, in the 1970s, Slovenia and Croatia finally had enough of Austrian rule. Sick of seeing the world "progress" while they were in a standstill, nationalist groups in Slovenia and Croatia demanded self-rule. Yet every time, the protests were suppressed, sometimes with deadly force, further causing Austria to grow more unpopular.
It wasn't long before Prussia become involved. Austria, which was once again crumbling, was quickly annexed by Prussia with little resistance before an all-out rebellion from Croatia can occur. Slovenia and Croatia, on the other hand, was given independence by the Kingdom of Prussia; Slovenia and Croatia was declared a separate state from Austria in March 12, 1975. Janez Dvornik was elected as Slovene-Croatia's first president.
A few months later, in July 8, Slovene-Croatia's new flag was adopted: a red-white-blue striped flag with the new coat of arms, consisting of a figure of Mount Triglav inside a shield, the highest point in Slovene-Croatia, with five, smaller shields on top, being the ancient arms of five regions (Croatia, Dalmatia, Dubrovnik, Istria, and Slavonia). Later, in October 27, the Constitution of Slovene-Croatia was developed. The country was promised elections in 1980, which was more recently met by reelection to a second five-year team by Janez Dvornik.
Slovene-Croatia remains somewhat weaker compared to its neighboring countries, though the country's economy has steadily improved within the short five year time span. Serbia remains a problem, however, with her intention to "reunite" Yugoslavia. Slovene-Croatia, however, identify themselves as a separate ethnic group to Serbs. To many people, they fear that Serbia will attempt to dominate Slovene-Croatia, similar to how Austria-Hungary and Austria dominated them before.
President Dvornik took action rapidly, settling down with an agreement with Prussia to allow them access to their Mediterranean ports if Prussia sends troops to defend the country from a possible Serbian attack. To the Slovenes and Croatians, the future of the country remains uncertain as the enemy is closing upon them...
