Rama I (Buddha Yodfa Chulaloke) Chakri

Gen 1 · 1737 - 1809

Buddha Yodfa Chulaloke, known as Rama I, founded the Chakri dynasty in 1782 after the fall of the Thonburi kingdom and established Bangkok as the new capital of Siam on the east bank of the Chao Phraya River. Born in Ayutthaya in 1737, he rose through military ranks under King Taksin before taking the throne himself. As king, he rebuilt Siamese administration, law, and religion after decades of war with Burma, commissioning a revised legal code and restoring Buddhist temples and texts. His son with chief consort Amarindra, Isarasundhorn, succeeded him as Rama II. He reigned until his death in 1809 and remains the dynasty's namesake, its royal house named for his pre-royal title, Chao Phraya Chakri.

Rama II (Buddha Loetla Nabhalai) Chakri

Gen 2 · 1767 - 1824

Buddha Loetla Nabhalai, known as Rama II, ruled Siam from 1809 to 1824 as the second monarch of the Chakri dynasty. Born in 1767, the son of Rama I and Queen Amarindra, he is remembered chiefly as a poet-king who revived Siamese literature and classical arts after the disruptions of the eighteenth century, personally composing verse and sponsoring the royal poets of his court. He fathered two sons who would each later reign as king: Prince Jessadabodindra, by consort Sri Sulalai, who became Rama III, and Prince Mongkut, by principal queen Sri Suriyendra, who became Rama IV. He died in Bangkok in 1824.

Rama III (Nangklao) Chakri

Gen 3 · 1788 - 1851

Phra Nangklao, known as Rama III, reigned as King of Siam from 1824 to 1851, succeeding his father Rama II ahead of his more senior half-brother, the future Rama IV. Born in 1788, he expanded Siam's trade with China and, later in his reign, with Western powers, while overseeing military campaigns that secured Siamese influence over Laos and Cambodia. A devout patron of Buddhism, he sponsored the restoration and construction of numerous temples, including Wat Pho and Wat Arun in Bangkok. He never married a principal queen and left no heir positioned to succeed him, so on his death in 1851 the throne passed to his half-brother Mongkut, who became Rama IV.

She lived to see her son and grandson (Rama III) both reign, dying in 1826 at an advanced age, one of the longest-lived consorts of the early dynasty.

Somdet Phra Sri Suriyendra (born Boonrod) was the principal queen consort of King Rama II and mother of Prince Mongkut, who later reigned as Rama IV. Born in 1767, she was a cousin of her husband and held the highest rank among his consorts, giving her son a strong claim to the succession that was nonetheless passed over in 1824 in favor of his older half-brother, Rama III. She lived to see Mongkut spend nearly three decades as a Buddhist monk before finally ascending the throne in 1851, though she died in 1836, some years before his accession.

Sri Sulalai Chakri

Gen 2 · 1770 - 1837

Somdet Phra Sri Sulalai (born Riam) was a royal consort of King Rama II and mother of his eldest surviving son, Prince Jessadabodindra, who reigned as Rama III. Born around 1770 near Nonthaburi, she came from a family involved in the court's confectionery service rather than high nobility, and never held the rank of queen. Her son's accession in 1824, chosen by the Accession Council over more senior-born half-brothers including the future Rama IV, made her one of the most consequential royal mothers of the early Bangkok era. She was posthumously honored with the title Somdet Phra Sri Sulalai. She died in 1837.

Hohenzollern Family Tree - Prussia's Royal House from Frederick the Great to Kaiser Wilhelm II

The House of Hohenzollern is the German dynasty that ruled Brandenburg from 1415, held the Prussian crown from 1701, and gave Germany its three emperors between 1871 and the fall of the monarchy in 1918. This tree follows the senior Prussian line in one unbroken descent, from Frederick William the Great Elector, through the kings of Prussia and the German Emperors, down to Georg Friedrich, Prince of Prussia, the present head of the house. ## Origins The family takes its name from Hohenzollern Castle on a hill in the Swabian Alb, where a line of counts is recorded from the eleventh century. A Swabian Zollern married into the burgraviate of Nuremberg in 1192, and the Franconian branch that grew from it spent two centuries accumulating lands and credit with the Holy Roman Emperors. The decisive moment came in 1415, when Emperor Sigismund invested Frederick VI of Nuremberg as Elector of Brandenburg in return for his political and financial support. The Duchy of Prussia, a separate inheritance lying outside the Empire, passed to the Brandenburg electors in 1618, and Frederick William, the Great Elector, welded the two into a single functioning state after the devastation of the Thirty Years' War. ## Notable members Frederick I turned the electorate into a kingdom in 1701. His son Frederick William I, the Soldier King, built the army and the treasury that his own son, **Frederick the Great**, used to seize Silesia and to make Prussia a European power, while also composing music, building Sanssouci and corresponding with Voltaire. **Queen Louise** became the emotional centre of Prussian resistance to Napoleon. **Wilhelm I**, with Otto von Bismarck as his minister president, was proclaimed German Emperor at Versailles in 1871. His son **Frederick III** and the liberal English princess he married, Victoria, daughter of Queen Victoria, reigned for only ninety nine days. **Wilhelm II**, the last Kaiser, abdicated in 1918 and died in Dutch exile in 1941. ## Significance No other German family shaped the modern state so directly. Hohenzollern rulers created the Prussian civil service, compulsory schooling and the general staff, sponsored the Berlin academies and the Humboldt university model, and then used Prussian power to unify Germany around themselves. The monarchy ended with the revolution of November 1918, but the house continues as a private family: the headship passed from Wilhelm II to his eldest son, then to Louis Ferdinand, and in 1994 to Georg Friedrich, whose own father and uncles are part of the succession story told in this tree. ## Quick facts | Fact | Details | |---|---| | Family name | Hohenzollern | | Place of origin | Hohenzollern Castle, Swabia, southern Germany | | Ruled | Brandenburg from 1415, Prussia from 1618, Germany from 1871 | | Royal title | King in Prussia from 1701, King of Prussia from 1772 | | Imperial title | German Emperor, 1871 to 1918 | | German Emperors | Wilhelm I, Frederick III, Wilhelm II | | Monarchy ended | 9 November 1918 | | Present head of the house | Georg Friedrich, Prince of Prussia, since 1994 | | Principal residences | Berlin City Palace, Sanssouci and Cecilienhof at Potsdam, Charlottenburg | | Branch shown here | The senior Prussian line only, not Hohenzollern-Sigmaringen |

Stuart Family Tree - The House of Stuart from Mary, Queen of Scots to Bonnie Prince Charlie

The House of Stuart was the royal dynasty that ruled Scotland from 1371 and both Scotland and England from 1603 until 1714, giving Britain fourteen monarchs from Robert II to Queen Anne as well as the Jacobite claimants who carried its cause into exile. Spelled Stewart in Scotland and Stuart after Mary, Queen of Scots adopted the French form, the family holds the unusual distinction of having united two crowns by inheritance rather than conquest, and of ending in a disputed succession that reshaped the British constitution. ## Origins The family took its name from its office. The Stewarts were hereditary High Stewards of Scotland, a post granted in the twelfth century to a Breton house settled in Renfrewshire. In 1315 Walter Stewart, 6th High Steward, married Marjorie Bruce, daughter of King Robert the Bruce. Their son became Robert II in 1371 when the direct Bruce line failed, and the stewardship turned into a crown. For more than two centuries afterwards the Stewarts ruled Scotland alone, through a run of reigns cut short by battle, captivity and long royal minorities that left the nobility unusually powerful. ## Notable members James IV, the most cultivated of the Scottish kings, married Margaret Tudor in 1503 and so planted the claim that would carry his descendants to the English throne. His granddaughter Mary, Queen of Scots became queen at six days old, reigned briefly and turbulently, and was deposed in 1567 and executed in England twenty years later. Her son, James VI of Scotland, inherited the English crown in 1603 as James I and became the first monarch to rule both kingdoms. His son Charles I lost the Civil Wars and his throne; Charles II returned at the Restoration in 1660; James II and VII was deposed in the Revolution of 1688, after which his daughters Mary II and Anne reigned in his place. In exile his son James Francis Edward Stuart and grandson Charles Edward Stuart, remembered as Bonnie Prince Charlie, led the Jacobite attempts to recover the throne, ending with the rising of 1745. ## Significance No other British dynasty changed the shape of the state so much. The Stuarts brought Scotland and England under one sovereign, presided over the King James Bible and the theatre of Shakespeare's late career, lost a king to Parliament, and provoked the settlements of 1689 and 1701 that made the monarchy answerable to Parliament and Protestant by statute. When Queen Anne died childless in 1714, the crown passed under the Act of Settlement to the descendants of her cousin Sophia of Hanover, granddaughter of James VI and I, so every British monarch since is still a Stuart descendant. | Fact | Details | | --- | --- | | Founder | Robert II, King of Scots from 1371 | | Ruled | Scotland 1371 to 1714; England and Ireland 1603 to 1714 | | Origin | Renfrewshire, Scotland | | Union of the Crowns | 1603, under James VI of Scotland and I of England | | Last reigning monarch | Anne, Queen of Great Britain, died 1714 | | Jacobite claimants | James Francis Edward, Charles Edward and Henry Benedict Stuart | | Succeeded by | The House of Hanover, through Sophia of Hanover |

Vanderbilt Family Tree - America's Gilded Age Dynasty

The Vanderbilts are an American family who rose from Dutch farming stock on Staten Island to hold the largest private fortune in the United States, built by Cornelius Vanderbilt, known as the Commodore, out of nineteenth century shipping and railroads, and known today for the Gilded Age houses their descendants built and for figures from Consuelo, Duchess of Marlborough, to the journalist Anderson Cooper. ## Origins on Staten Island The family descends from Jan Aertsen van der Bilt, a Dutch settler who reached New Netherland in the seventeenth century and whose descendants farmed on Staten Island for generations. Cornelius Vanderbilt (1794-1877) was born there, the son of a boatman, and began work as a teenager carrying freight across New York Harbour in a single sailing barge. He married his first cousin Sophia Johnson in 1813. ## The railroad fortune Vanderbilt moved from sail to steam, dominated the Hudson River and coastal trade, and after the Civil War turned to railroads, consolidating the New York Central system and building Grand Central Depot. He left almost the whole fortune to one son, William Henry Vanderbilt, who nearly doubled it in eight years before dividing it evenly among his own eight children. They built the family's great houses: The Breakers and Marble House at Newport, Biltmore House in North Carolina, Hyde Park on the Hudson, Florham in New Jersey and Shelburne Farms in Vermont. ## Notable members The third and fourth generations produced Consuelo Vanderbilt, who married the 9th Duke of Marlborough and became a social reformer in England; the sculptor Gertrude Vanderbilt Whitney, founder of the Whitney Museum of American Art; Alfred Gwynne Vanderbilt, who died in the sinking of the Lusitania; and Harold Stirling Vanderbilt, who won the America's Cup three times and invented contract bridge. The modern line runs through Reginald Claypoole Vanderbilt to the designer Gloria Vanderbilt and her son, the CNN anchor Anderson Cooper. ## Significance No American family is more closely identified with the Gilded Age. The Vanderbilts set the pattern for how new industrial wealth was spent, and then for how quickly such a fortune disperses across many heirs. What endures is institutional: Vanderbilt University, the Whitney Museum, and the houses at Newport, Hyde Park, Shelburne and Asheville that are now museums and public estates. | Fact | Details | | --- | --- | | Founder | Cornelius Vanderbilt (1794-1877), the Commodore | | Origin | Staten Island, New York, of Dutch descent | | Source of wealth | Steamboat shipping, then the New York Central railroads | | Famous houses | The Breakers, Marble House, Biltmore House, Hyde Park | | Best known members | Consuelo Vanderbilt, Gertrude Vanderbilt Whitney, Gloria Vanderbilt, Anderson Cooper | | Generations covered | Five, from the Commodore to Anderson Cooper |
