, Wolfgang William, Count Palatine of Neuburg, disregarded a 1647 agreement with Frederick William which had favored the Protestants in the duchies, while Frederick William insisted that the agreement be upheld. Besides these religious motives, Frederick William's invasion also aimed at territorial expansion.

The conflict had the potential to spark another international war since Wolfgang William wanted to have the still not demobilized army of Lorraine, which continued to operate in the region despite the Peace of Westphalia, to intervene on his side, and Frederick William sought support of the Dutch Republic

. The latter however followed a policy of neutrality and refused to aid Frederick William's campaign, which was furthermore opposed by the Imperial estates as well as the local ones. Politically isolated, Frederick William aborted the campaign after the Treaty of Cleves negotiated by Imperial mediators in October 1651. The underlying religious dispute was only solved in 1672. While military confrontations were avoided and the Brandenburg-Prussian army was primarily occupied with stealing cattle (hence the name), it considerably lowered Frederick William's reputation.

Standing army

Due to his wartime experiences, Frederick William was convinced that Brandenburg-Prussia would only prevail with a standing army

 was a privilege of the estates, yet Frederick William envisioned a standing army financed independently of the estates. He succeeded to get the consent and necessary financial contributions of the estates in a landtag decree of 26 July 1653. In turn, he confirmed several privileges of the knights, including tax exemption, assertion of jurisdiction and police powers on their estates (Patrimonialgerichtsbarkeit) and the upholding of serfdom
Serfdom
Serfdom is the status of peasants under feudalism, specifically relating to Manorialism. It was a condition of bondage or modified slavery which developed primarily during the High Middle Ages in Europe and lasted to the mid-19th century...

 (Leibeigenschaft, Bauernlegen).

Initially, the estates' contributions were limited to six years, yet the Frederick William obliged the estates to continue the payments thereafter and created a dedicated office to collect the contributions. The contributions were confirmed by the estates in 1662, but transformed in 1666 by decree from a real estate tax to an excise tax. Since 1657, the towns had to contribute not soldiers, but monetary payments to the army, and since 1665, the estates were able to free themselves from contributing soldiers by additional payments. The initial army size of 8,000 men had risen to 25,000 to 30,000 men by 1688. By then, Frederick William had also accomplished his second goal, to finance the army independently of the estates. By 1688, these military costs amounted to considerable 1,500,000 talers or half of the state budget. Ensuring a solid financial basis for the army, undisturbed by the estates, was the foremost objective of Frederick William's administrative reforms. He regarded military success as the only way to gain international reputation.

 in 1538). The margraviate's liabilities and tax income as well as the margrave's finances were controlled by the Kreditwerk, an institution not controlled by the elector, and the Großer Ausschuß ("Great Committee") of the estates. This was due to concessions made by Joachim II in 1541 in turn for financial aid by the estates, however, the Kreditwerk went bankrupt between 1618 and 1625. The margraves further had to yield the veto of the estates in all issues concerning the "better or worse of the country", in all legal commitments, and in all issues concerning pawn or sale of the elector's real property.

, started to centralize the Brandenburg-Prussian government with an attempt to establish the Geheimer Rat as a central authority for all territories in 1651, but this project proved to be unfeasible. Instead, the elector continued to appoint a governor (Kurfürstlicher Rat) for each territory, who in most cases was a member of the Geheimer Rat. The most powerful institution in the territories remained the governments of the estates (Landständische Regierung, named Oberratsstube in Prussia and Geheime Landesregierung in Mark and Cleves), which were the highest government agencies regarding jurisdiction, finances and administration. The elector attempted to balance the estates' governments by creating Amtskammer chambers to administer and coordinate the elector's domains, tax income and privileges. Such chambers were introduced in Brandenburg in 1652, in Cleves and Mark in 1653, in Pomerania in 1654, in Prussia in 1661 and in Magdeburg in 1680. Also in 1680, the Kreditwerk came under the aegis of the elector.

Frederick William's excise tax (Akzise), which since 1667 replaced the property tax raised in Brandenburg for Brandenburg-Prussia's standing army with the estates' consent, was raised by the elector without consultation of the estates. The conclusion of the Second Northern War

 had strengthened the elector politically, enabling him to reform the constitution of Cleves and Mark in 1660 and 1661 to introduce officials loyal to him and independent of the local estates. In the Duchy of Prussia, he confirmed the traditional privileges of the estates in 1663, but the latter accepted the caveat that these privileges were not to be used to interfere with the exertion of the elector's sovereignty. As in Brandenburg, Frederick William ignored the privilege of the Prussian estates to confirm or veto taxes raised by the elector: while in 1656, an Akzise was raised with the estates' consent, the elector by force collected taxes not approved by the Prussian estates for the first time in 1674. Since 1704, the Prussian estates had de facto relinquished their right to approve the elector's taxes while formally still entitled to do so. In 1682, the elector introduced an Akzise to Pomerania and in 1688 to Magdeburg, while in Cleves and Mark an Akzise was introduced only between 1716 and 1720. Due to Frederick William's reforms, the state income increased threefold during his reign, and the tax burden per subject reached a level twice as high as in France

Frederick William's testament would have divided Brandenburg-Prussia among his sons, yet firstborn Frederick III with the emperor's backing succeeded in becoming the sole ruler based on the Treaty of Gera, which forbade a division of Hohenzollern territories. In 1689, a new central chamber for all Brandenburg-Prussian territories was created, called Geheime Hofkammer (since 1713: Generalfinanzdirektorium). This chamber functioned as a superior agency of the territories' Amtskammer chambers. The General War Commissariat (Generalkriegskommissariat) emerged as a second central agency, superior to the local Kriegskommissariat agencies initially concerned with the administration of the army, but until 1712 transformed into an agency also concerned with general tax and police tasks.

 was sent to Guinea to erect the fortress Großfriedrichsburg. On 24 February 1684, another treaty with indigenous chiefs was signed that allowed the erection of a second fort in nearby Accada (now Akwida), named Dorotheenschanze after Frederick William's second wife. On 4 February 1685, a treaty was signed with the chiefs of Taccararay (now Takoradi), some 30 kilometers east of Großfriedrichsburg. A fourth fort was built at a spring near the village of Taccrama, between Großfriedrichsburg and Dorotheenschanze, named Loge or Sophie-Louise-Schanze. Overall, the colony comprised roughly 50 kilometers of coastline, and did not extend into the hinterland.

, who due to high maintenance costs abandoned it and demolished the fort soon after. On 27 July 1685, an expedition was mounted by Frederick William and Raule, who took possession of the vacated colony on 1 October. Subsequently, the fort was rebuild and contacts to the indigenous population established. France was alarmed and sent a vessel to re-conquer the fort in late 1687, but the attack of a French frigate and a smaller vessel was beaten back by the Brandenburg-Prussian garrison. The victory improved the relations to the indigenous people, many of whom were carried off as slaves by the French before. While Arguin did not reach the economic importance of Großfriedrichsburg, it temporarily advanced to the world's primary staple port for rubber.
