Hohenzollern in the context of "Ferdinand I of Romania"

Frederick II (German: Friedrich II.; 24 January 1712 – 17 August 1786) was the monarch of Prussia from 1740 until his death in 1786. He was the last Hohenzollern monarch titled King in Prussia, declaring himself King of Prussia after annexing Royal Prussia from the Polish–Lithuanian Commonwealth in 1772. His most significant accomplishments include military successes in the Silesian wars, reorganisation of the Prussian Army, the First Partition of Poland, and patronage of the arts and the Enlightenment. Prussia greatly increased its territories and became a major military power in Europe under his rule. He became known as Frederick the Great (German: Friedrich der Große) and was nicknamed "Old Fritz" (German: der Alte Fritz).

In his youth, Prince Frederick was more interested in music and philosophy than war, which led to clashes with his authoritarian father, Frederick William I of Prussia. However, upon ascending to the throne, he attacked and annexed the rich Austrian province of Silesia in 1742, winning military acclaim. He became an influential military theorist, whose analyses emerged from his extensive personal battlefield experience and covered issues of strategy, tactics, mobility and logistics.

Sigmaringen (German pronunciation: [ˈziːkmaʁɪŋən] ; Swabian: Semmerenga) is a town in southern Germany, in the state of Baden-Württemberg. Situated on the upper Danube, it is the capital of the Sigmaringen district.

Sigmaringen is renowned for its castle, Schloss Sigmaringen, which was the seat of the principality of Hohenzollern-Sigmaringen until 1850 and is still owned by the Hohenzollern family.

Victoria, Princess Royal (Victoria Adelaide Mary Louisa; 21 November 1840 – 5 August 1901) was German Empress and Queen of Prussia as the wife of Frederick III, German Emperor. She was the eldest child of Queen Victoria of the United Kingdom and Prince Albert of Saxe-Coburg and Gotha and was created Princess Royal in 1841. As the eldest child of the British monarch, she was briefly heir presumptive until the birth of her younger brother, the future Edward VII. She was the mother of Wilhelm II, the last German Emperor.

Educated by her father in a politically liberal environment, Victoria was married at the age of 17 to Prince Frederick of Prussia, with whom she had eight children. Victoria shared with Frederick her liberal views and hopes that Prussia and the later German Empire should become a constitutional monarchy, based on the British model. Criticised for this attitude and for her English origins, Victoria suffered ostracism by the Hohenzollerns and the Berlin court. This isolation increased after the rise to power of Otto von Bismarck, one of her staunchest political opponents, in 1862.

Berlin Cathedral (German: Berliner Dom), also known as the Evangelical Supreme Parish and Collegiate Church, is a monumental German Protestant church and dynastic tomb (House of Hohenzollern) at the Lustgarten on the Museum Island in central Berlin. Having its origins as a castle chapel for the Berlin Palace, several structures have served to house the church since the 15th century. The present collegiate church was built from 1894 to 1905 by order of Emperor William II according to plans by Julius Raschdorff in Renaissance and Baroque Revival styles. The listed building is the largest Protestant church in Germany and one of the most important dynastic tombs in Europe. In addition to church services, the cathedral is used for state ceremonies, concerts and other events.

Since the demolition of the Memorial Church (Denkmalskirche) section on the north side by the East German authorities in 1975, Berlin Cathedral has consisted of the large Sermon Church (Predigerkirche) in the center, and the smaller Baptismal and Matrimonial Church (Tauf- und Traukirche) on the south side and the Hohenzollern crypt (Hohenzollerngruft), which covers almost the entire basement. Damaged during the Allied bombing in World War II, the cathedral's original interior was restored by 2002. Currently there is discussion about restoring the historical exterior as well.

Albert Frederick (German: Albrecht Friedrich; Polish: Albrecht Fryderyk; 7 May 1553 – 27 August 1618) was the Duke of Prussia, from 1568 until his death. He was a son of Albert of Prussia and Anna Marie of Brunswick-Lüneburg. He was the second and last Prussian duke of the Ansbach branch of the Hohenzollern family.

Princess Marie Luise Alexandra Karoline of Hohenzollern-Sigmaringen (17 November 1845 – 26 November 1912), later Countess of Flanders, was a princess of Hohenzollern-Sigmaringen, later simply of Hohenzollern. She married Prince Philippe, Count of Flanders, second son of King Leopold I of Belgium, and she was the mother of King Albert I.
