The Reign of Gustav Vasa:AD 1523-1560
The reign of Gustav Vasa can be argued to be one of the best in European history. In 1523, Sweden, was one of the poorest nations in Europe, it's army poorly armed and trained, the diplomatic situation was desperate.
Gustav Vasa created an elite guard known as the Vasa Imperial Guard. Numbering at 5,000, these men were equiped with good weapons and trained for 6 months, they also had the first artillery in the history of the Swedish army.
The first 15 years saw Swedish stability improved[+2] and the economy thrive due to a massive increase in baltic trade. The money, stability, and the elite military would be hard pressed in the first Scandinavian War.
Scandinavian War
By 1540, Sweden, had changed for the better. It's economy and military had improved so much that Sweden was expected to become a great power in 10 to 20 years.
The Danish king, Christian II, was a ruthless man would had a burning desire to annex Sweden. The Danish military was one of the best in Europe, it had a large navy and it's army was well armed and trained.
The war began with a simple plan for Sweden. War Taxes would be collected and a loan from the new Bank of Sweden would be taken out. The entire Swedish army[excluding the army in Mecklenburg]would capture as many provinces and kill as many Danish soldiers as possible.
Gustav Vasa lead the army personally and began a bloddy rampage through Denmark. The Danish and Swedish armies fought desperate battles which lead to few victorys, many defeats, and some stalemates.
The naval war did not go well for Sweden, they could not gain the upper hand and were forced to stay in port for most of the war.
The war turned when Sweden captured a province in mainland Denmark. The Danish people tired of war and surprised of the major defeat wanted to end the war. Finally in 1543 the ended with 25,000 Swedes and 34,000 Danes dead, 13 ships on both sides lost.
The North German War:AD 1543-1552
The Mecklenburg War had seen allies betray each other and nations commit atrocites. The major rivalry in North Germany were between Saxony and Bohemia. Bohemia had England and Pommern as an ally, Saxony had Brandenburg and Denmark as allies.
Sweden and Denamark planned to stay out of the war, their economies were drained and their armies small and weak.
When Bohemia finally declared war in March she called on her allies which entered the war. Saxony called on her allies and after a string of political events, Denmark relutently entered the war. The year after, Saxony, using the Danish/Swedish rivalry,asked Sweden to join her. Gustav Vasa decided that if Denmark was to be destroyed then this was the perfect time so Sweden entered the war.
The fighting was bloddy and entire armies were crushed. Sweden used several good generals to capture provinces but the war took it's toll. Thousands were dieing and even the new use of mobile artillery could not prevent this.
Battle after battle armies parished and borders were redrawn. Austria entered the war in 1546, so did the Netherlands. Sweden had 2 bank loans and had war taxed the country to the depths of the peasants pockets[-2].
Finally in 1552, Sweden, left the war, it was a bloddy war which resulted in the lives of 46,000 Swedes and 17 ships. It is estimated that 6,700 ducats were spent on this war. For the remaining 8 years of Gustav Vasa's rule, Sweden, would stabilize and establish a powerful elite[yet small] military, a massive trade empire would be started and relations with Denmark and Russia would improve to the point of an alliance.
