Philip William, Prince in Prussia (German: Philipp Wilhelm von Brandenburg-Schwedt; May 19, 1669, castle of Königsberg – December 19, 1711, castle of Schwedt) was a Prussian Prince, the first Margrave of Brandenburg-Schwedt and governor of Magdeburg from 1692 to 1711.
Philip William was the eldest son of the Great Elector's second marriage to Princess Sophia Dorothea. One of her major endeavours was to ensure the financial security of her sons, mostly by the purchase of land. Shortly after the birth of Philip William he was invested with his mother's dominion of Schwedt, later, the Brandenburg-Prussian government added the lands of Wildenbruch. Both dominions were improved by Princess Dorothea's care and investments. Following the death of his mother, Philip, in an accord of dating to 3 March 1692, reached agreement with his half-brother, the Elector Friedrich III, about income and lands left to him by the Great Elector, including the lordship, without sovereignty, of Halberstadt. Philip received for himself and his descendants guaranteed appanages generating an income of 24,000 thalers each year. Added revenue came in to the amount of 22,000 thalers from the rule of Schwedt, plus military salaries of about 20,000 thalers, so that with a total income of 66,000 crowns he was enabled to hold court, in some style, himself.
He held like all the male members of his house the courtesy title of "Margrave of Brandenburg". After the coronation of his elder brother Frederick, he became "Prince in Prussia, Margrave of Brandenburg" with the title "Royal Highness". The nomenclature "Brandenburg-Schwedt" came into use in the 19th Century, posthumously, to distinguish the lords of Schwedt from the main line of the Hohenzollerns. Philip William was the ancestor of the Schwedt branch of the royal House of Hohenzollern. On 25 January 1699 Philip Wilhelm married Princess Johanna Charlotte of Anhalt-Dessau (1682–1750), daughter of John George II, Prince of Anhalt-Dessau. As a widow she became Abbess of the Imperial Abbey of Herford.
Philipp Wilhelm served as a general in the campaigns against France and was promoted in 1697 to a "general field-marshal" and commander-in-chief of the artillery. His half-brother, Prince Elector Friedrich III (later King Frederick I of Prussia), also gave him the proprietership of several regiments. During his time as governor of Magdeburg, he was raised by the University of Halle (Saale) to the post of "Rector magnificentissimus”.
Philip's Berlin's residence, the Margrave Weilersche Palace, was later used by Kaiser Wilhelm I. He was buried in the Berlin Cathedral, where most of the senior members of the House of Hohenzollern are buried.
Since Philip's eldest son Frederick William was a minor at his death, the King of Prussia (Frederick I and Frederick William I) took over guardianship. With the death of his granddaughter, Anna Elisabeth Luise, the collateral line of Brandenburg-Schwedt became extinct in 1820.
