The House of Hohenzollern is a noble family and royal dynasty of electors, kings and emperors of Prussia, Germany and Romania. It originated in the area around the town of Hechingen in Swabia during the 11th century. They took their name from their ancestral home, the Burg Hohenzollern castle near Hechingen.
The family uses the motto Nihil Sine Deo (English: Nothing Without God). The family coat of arms, first adopted in 1192, began as a simple shield quarterly sable and argent. A century later, in 1317, Frederick IV, Burgrave of Nuremberg, added the head and shoulders of a hound as a crest. Later quartering reflected heiresses’ marriages into the family.
The family split into two branches, the Catholic Swabian branch and the Protestant Franconian branch, known also as the Kirschner line. The Swabian branch ruled the area of Hechingen until the revolution of 1848/49. The Franconian branch was more successful: members of the Franconian branch became Margrave of Brandenburg in 1415 and Duke of Prussia in 1525. Following the union of these two Franconian lines in 1618, the Kingdom of Prussia was created in 1701, eventually leading to the unification of Germany and the creation of the German Empire in 1871.
Social unrest at the end of World War I led to the German Revolution of 1918, with the formation of the Weimar Republic forcing the Hohenzollerns to abdicate, thus bringing an end to the modern German monarchy. The Treaty of Versailles in 1919 set the final terms for the dismantling of the German Empire..
One of the most prominent ruling houses in the history of Europe, the Hohenzollern Dynasty played a major role in the history of Germany from the late Middle Ages until the end of World War I. It takes its name from a castle in Swabia first mentioned as Zolorin or Zolre (the modern Hohenzollern, south of Tübingen, in the Land Baden-Württemberg).
Counts of Zollern (before 1061–1204) 
The oldest known mention of the Zollern was in 1061 by Berthold of Reichenau. It was a county, ruled by the counts of Zollern, whose descent has been attempted to be linked (without success) to the Burchardinger dynasty.
- until 1061: Burkhard I
- before 1125: Frederick I
- between ca. 1125 and 1142: Frederick II, eldest son of Frederick I:XLI
- between ca. 1143 and 1150-1155: Burkhard II, 2nd oldest son of Frederick I:XLI
- between ca. 1150-1155 and 1160: Gotfried of Zimmern, 4th oldest son of Frederick I:XLI
- before 1171 – c. 1200: Frederick III/I (son of Frederick II, also Burgrave of Nuremberg)
Count Frederick III of Zollern was a loyal retainer of the Holy Roman Emperors Frederick Barbarossa and Henry VI, and around 1185 he married Sophia of Raabs, the daughter of Conrad II, Burgrave of Nuremberg.
After the death of Conrad II, often referred to as Kurt II who left no male heirs, Frederick III was granted the burgraviate of Nuremberg in 1192 as Burgrave Frederick I of Nuremberg-Zollern. Since then the family name has been Hohenzollern.
After Frederick's death, his sons partitioned the family lands between themselves:
- The older brother, Frederick IV, received the county of Zollern and burgraviate of Nuremberg in 1200 from his father, thereby founding the Swabian branch of the House of Hohenzollerns. The Swabian line remained Catholic.
- The younger brother, Conrad III, received the burgraviate of Nuremberg from his older brother Frederick IV in 1218, thereby founding the Franconian branch of the House of Hohenzollern. The Franconian line later converted to Protestantism.
Franconian cadet branch and Brandenburg-Prussian Branch 
The cadet Franconian branch of the House of Hohenzollern was founded by Conrad III, Burgrave of Nuremberg.
Beginning in the 16th century, this branch of the family became Protestant and decided on expansion through marriage and the purchase of surrounding lands.
These acquisitions eventually transformed the Hohenzollerns from a minor German princely family into one of the most important in Europe.

Reigning (1871–1918) 
In 1871 the German Empire was proclaimed. With the accession of Wilhelm I to the newly-established imperial German throne, the titles of King of Prussia, Duke of Prussia and Elector of Brandenburg were always attached to the title of German Emperor.

Line of succession (1918 to present) 
Despite the abolition of the German monarchy in 1918, the House of Hohenzollern never relinquished their claims to the thrones of Prussia and the German Empire. These claims are linked by the Constitution of the second German Empire: according to this, whoever was King of Prussia was also German Emperor. However, these claims are not recognised by the Federal Republic of Germany.
|William II||1918–1941||Exiled in the Netherlands until his death|
|Crown Prince William||1941–1951|
|Prince Louis Ferdinand||1951–1994|
|Prince Georg Friedrich||since 1994|
|Prince Carl Friedrich||heir presumptive|
The head of the house is the titular King of Prussia and German Emperor. He also bears a historical claim to the title of prince of Orange. Members of this line style themselves princes of Prussia.
Genealogy and Coat of arms of the Hohenzollerns, Brandenburg, Prussia, and the German Empire 
On January 27, 1701, King Frederick I changed his arms as prince-elector of Brandenburg. The older arms of the electors of Brandenburg depicted a red eagle on a white background. Henceforth, the Prussian eagle, now royally crowned and with 'FR' (Fridericus Rex, "King Frederick") on its breast, was placed in an escutcheon on the shield with 25 quarters instead of the electoral scepter. All the helmets made way for one royal crown.
The wild men—figures from Germanic and Celtic mythology representing the 'Lord of the Beasts' or 'Green Man'— that held the arms of Prussia are probably taken from the arms of Pomerania or Denmark. They are also to be found as supporters of the arms of Braunschweig, Königsberg, and the Dutch towns of Anloo, Beilen, Bergen op Zoom, Groede, Havelte, 's-Hertogenbosch, Oosterhesselen, Sleen, Sneek, Vries and Zuidwolde. A wild man and a wild woman have held the shield of the principality of Schwarzburg in Thuringia and the city of Antwerp since the beginning of the 16th century. Two wild men and a wild woman have been included in the seal of Bergen op Zoom since 1365.
A decree from 11 February 1701 placed a crown on the Prussian escutcheon. The king ordained that the whole should be placed on a royal pavilion after the French and Danish examples.
When William, Prince of Orange and King of Great Britain died on March 19, 1702, the king ordered the arms of the principality placed on his shield. This was to support his claim as sole heir by his mother, although the Frisian branch of the House of Orange-Nassau claimed it as well.
In 1708 Frederick announced that he would place the quarters of the dukes of Mecklenburg in the Prussian arms to stress his rights to Mecklenburg-Schwerin and Mecklenburg-Strelitz if their ducal lines were to die out. Although Mecklenburg-Strelitz protested, Emperor Joseph I gave permission to Frederick in October 1712. This design was twice officially altered but was not fundamentally changed since.
The electoral scepter had its own shield under the electoral cap. Around the shield, with 36 quarters (including Veere-Vlissingen and Breda), appeared the Order of the Black Eagle with a crowned helmet resting on top. The wild men held banners of Prussia and Brandenburg and behind the pavilion rose a Prussian banner after the example of the French Oriflamme. The motto Gott mit uns ("God with us") appeared on the pedestal.
Already during the reign of Frederick I there is a notable difference between the 'Gothic' representation of the Prussian eagle in the arms and the more naturally depicted and often flying eagle on most coins and military standards.
Frederick William I followed his father on the throne on February 25, 1713. According to Ströhl he gave the eagle a scepter and orb. He made an arrangement with the Frisian Nassaus over the title to the Principality of Orange, although it was occupied by France. Besides the arms of Orange, he officially added Veere and Vlissingen on July 29, 1732. The king also added East Frisia to his arms, claiming it in case the prince would die without heir. A fourth escutcheon appeared among the 36 quarters.
Frederick II became king on May 31, 1740. He laid claim to the duchy of Silesia after the death of Emperor Charles VI and declared war on Charles' daughter and heir, Maria Theresa of Austria, thereby starting the Silesian Wars.
Frederick II was followed by his nephew, Frederick William II, on August 17, 1786. Frederick William II inherited the Franconian cadet branches (Ansbach and Bayreuth) of the House of Hohenzollern in 1791. For reasons of economy, however, the official seals were unchanged.
Frederick William III took the throne on November 16, 1797 and changed the arms on July 3, 1804. The reorganisation of Germany by Napoleon I of France made alterations necessary. A new escutcheon was created for Silesia and the shield held 42 quarters. The Order of the Red Eagle of the Franconian line was also added around the shield.
After the fall of Napoleon, Prussia gained extensive territories on the Rhine and in Saxony. New arms were therefore decreed on January 9, 1817. The number of quarters rose to 48, including the horse of Westphalia and Lower Saxony. The number of escutcheons was reduced to four: the black eagle of Prussia, the red eagle of Brandenburg instead of the scepter, the burgravate of Nuremberg (though ceded to Bavaria), and Hohenzollern proper.
The so-called 'middle arms' were then issued: a shield with the same four escutcheons and ten quarters for Silesia, Rhineland, Posen, Saxony, Pomerania, Magdeburg, Jülich-Cleves-Berg, and Westphalia. This was encircled by the Order of the Black Eagle and held by two wild men with clubs.
The small arms already in use on coins of the 1790s were legitimized as well.
Frederick William IV was followed by his brother William I on January 2, 1861. He changed the arms on 11 January 1864 by combining the escutcheons of Nuremberg and Hohenzollern. After the Second Schleswig War of 1864 and the Austro-Prussian War of 1866, Prussia annexed Schleswig, Holstein, Hanover, Hesse-Kassel (or Hesse-Cassel), and Nassau. King William I of Prussia became William I, German Emperor on 18 January 1871 during the unification of Germany. The Kingdom of Prussia became the predominant state in the newly-created German Empire.
William decreed new arms on August 16, 1873. The number of quarters was again 48 with three escutcheons. Added were the collars of the Order of the House of Hohenzollern and the Order of the Prussian Crown. The motto was placed on the dome of the pavilion.
The middle arms of 1873 show more clearly the changes by the additions of Schleswig-Holstein, Hanover, and Hesse-Kassel and the removals of Magdeburg and Cleves-Jülich-Berg.
The Reichsadler had already been introduced at the Proclamation of Versailles, although the first version had been only a provisional one. The design of the eagle had been altered at least twice during the German Empire (1871–1918). It shows the imperial eagle, a realistic black eagle, with the crown of the Holy Roman Empire. The eagle has a red head and claws, with open wings and feathers, but only one head, looking to the right. This is in contrast to its predecessor, the eagle of the German Confederation, because it symoblised that important parts of the old empire, Austria and Bohemia, were not part of this new empire. Its legal basis was an imperial rescript:
To the Reich Chancellor Prince of Bismarck. Following your report of June 27 of this year I authorize: 1. that public authorities and public servants, appointed by the Emperor according the requirements of the constitution and the laws of the German Empire, are to be called imperial; 2. that the black, one-headed, rightward-looking eagle with red beak, tongue and claws, without scepter and orb, on the breast shield the Prussian eagle, overlaid with the shield of the House of Hohenzollern, over the same the crown in the form of the crown of Charlemagne, but with two crossing bows, may be brought into use; 3. that the Imperial standard [Script continues]—Kaiser Wilhelm, Rescript of August third, 1871, concerning the names of the public authorities and public servants of the German Empire, as well as the declaration of the Imperial coat of arms and the Imperial standard

Below is an overview table of the relationships of the House of Hohenzollern:
Swabian senior branch 
Ruling the minor German principalities of Hechingen, Sigmaringen and Haigerloch, this branch of the family decided to remain Roman Catholic and from 1567 onwards split into the Hohenzollern-Hechingen, Hohenzollern-Sigmaringen and Hohenzollern-Haigerloch branches. The Romanian branch of this family became Orthodox, starting from Ferdinand's I children. When the last count of Hohenzollern, Charles I of Hohenzollern (1512–1579) died, the territory was to be divided up between his three sons:
- Eitel Frederick IV of Hohenzollern-Hechingen (1545–1605)
- Charles II of Hohenzollern-Sigmaringen (1547–1606)
- Christopher of Hohenzollern-Haigerloch (1552–1592)
They never expanded from these three Swabian principalities, which was one of the reasons they became relatively unimportant in German history for much of their existence. However, they kept royal lineage and married members of the great royal European houses.
In 1767 the principality of Hohenzollern-Haigerloch was incorporated into the other two principalities. In 1850, the princes of both Hohenzollern-Hechingen and Hohenzollern-Sigmaringen abdicated their thrones, and their principalities were incorporated as the Prussian province of Hohenzollern.
The last ruling Prince of Hohenzollern-Sigmaringen, Karl Anton, would later serve as Minister-President of Prussia between 1858 and 1862.
However, a member of the Hohenzollern-Sigmaringen family, Charles Eitel, second son of prince Karl Anton, was chosen to become prince of Romania as Charles I in 1866. In 1881 Charles I became the first king of the Romanians.
Charles' older brother, Leopold, was offered the Spanish throne after a revolt removed queen Isabella II in 1870. Although encouraged by Bismarck to accept it, Leopold backed down once France's Emperor, Napoleon III, stated his objection. Despite this, France still declared war, beginning the Franco-Prussian war.
Charles I had only a daughter who died very young, so Leopold's younger son Ferdinand I would succeed his uncle as king of the Romanians in 1914, and his descendants continued to rule in Romania until the end of the monarchy in 1947.
In modern times this branch has been represented only by the last king, Michael I of Romania, and his daughters. The descendants of Leopold's oldest son William continue to use the titles of prince or princess of Hohenzollern.
King Michael renounced his connection in 2011.

In 1850 the principality was sold to the Franconian branch of the family and incorporated into the kingdom of Prussia. Nevertheless, the family continued to use the princely title of Fürsten von Hohenzollern-Sigmaringen until 1869 and still use the title of Fürsten von Hohenzollern.
Kings of the Romanians 
Reigning (1866–1947) 
The Principality of Romania was established in 1862, after the Ottoman vassal states of Wallachia and Moldavia had been united in 1859 under Alexandru Ioan Cuza as Prince of Romania in a personal union.

In 1947 the Kingdom of Romania was abolished and replaced with the People's Republic of Romania.
Succession (1947 until today) 
Michael has retained his claim on the defunct Romanian throne. At present, the claim is not recognised by Romania, a republic. At 10 May 2011, Michael severed all of the dynastic and historical ties between the House of Romania and the House of Hohenzollern.
House of Hohenzollern-Sigmaringen 
The princely House of Hohenzollern-Sigmaringen never relinquished their claims to the princely throne of Hohenzollern-Sigmaringen or the royal throne of Romania. Because the last reigning king of the Romanians, Michael I, has no male issue, upon his death the claim will devolve to the head of the House of Hohenzollern-Sigmaringen (or to the king's female line descendants, if one follows the amended Romanian house laws).
