Editing Frederick V of the Palatinate (section)

==Death==
In 1630, King [[Gustavus Adolphus of Sweden]] intervened in the [[Thirty Years' War]] on the Protestant side. He won the [[Battle of Breitenfeld (1631)]] against the Imperial army and marched into southern Germany. When the Swedes captured [[Oppenheim]] in December 1631, Frederick believed the time was ripe for him to reestablish himself in the Palatinate, and he left for [[Heidelberg]].

In February 1632, Frederick met Gustavus Adolphus at [[Frankfurt]], with Gustavus Adolphus paying Frederick full royal honours. However, Gustavus Adolphus did not  offer Frederick support for restoring him in the Palatinate because England and the Netherlands had not signed off on such a proposal.

Frederick subsequently took part in Gustavus Adolphus' march into the [[Duchy of Bavaria]], and was present for the march into [[Munich]] on 17 May 1632. He pressed his case with Gustavus Adolphus, who told Frederick that he would accept Frederick's restoration without Dutch/British support only if Frederick would agree to hold the Palatinate as a [[fief]] of the King of Sweden. The lands of the Palatinate were simply too important strategically for Gustavus Adolphus to hand them over to Frederick. Gustavus Adolphus also insisted that Frederick would have to establish equal rights for [[Lutherans]] in his territories. Frederick refused Gustavus Adolphus' conditions and they parted. Frederick travelled to Swedish-occupied [[Mainz]], intending to return to the Hague.

About this time, England finally determined to send an expeditionary force to Germany. Unfortunately for Frederick, it was too late. Gustavus Adolphus was killed at the [[Battle of Lützen (1632)]] on 16 November, and in October, Frederick developed an infection that got worse in the following weeks. The famed physician [[Peter Spina]] was summoned from Darmstadt to Mainz, but nothing could be done for Frederick. He died on the morning of 29 November 1632, of a "pestilential fever".

Frederick's son and heir, [[Charles I Louis, Elector Palatine|Charles Louis]], was only 15 years old. Therefore, his uncle, Frederick's brother [[Louis Philip, Count Palatine of Simmern-Kaiserslautern|Ludwig Philipp of Simmern-Kaiserslautern]], served as regent. Frederick's internal organs were buried at St. Catherine's in [[Oppenheim]] and his embalmed body was taken to [[Frankenthal]]. On 9 June 1635, with Spanish troops approaching, Ludwig Philipp fled to [[Kaiserslautern]] with Frederick's body. It is believed that Ludwig Philipp transferred Frederick's body to [[Sedan, Ardennes|Sedan]] in September 1637, but Frederick's final resting place is unknown.
