Royal boy names
Every name on this page was worn by a real reigning monarch, and every entry says which crown and how many — nothing is here for merely sounding regal.
- WilliamWIL-yumEngland
Four kings of England and Britain: the Conqueror in 1066, Rufus, William III and William IV. The present Prince of Wales will be the fifth.
- HenryHEN-reeEngland
Eight kings of England, Henry I to Henry VIII, and four kings of France as Henri. No English name has been on the throne longer.
- EdwardED-wardEngland
Eight numbered kings, Edward I to Edward VIII in 1936 — plus three Anglo-Saxon Edwards before the Conquest, including the Confessor, whom the heralds never numbered.
- GeorgeJORJBritain
Six kings of the United Kingdom, from the Hanoverian George I in 1714 to George VI. Before 1714 the name was barely used in England at all.
- CharlesCHARLZBritain
Three British monarchs, most recently Charles III, and ten kings of France counting Charlemagne as the first of them.
- JamesJAYMZScotland
Seven kings of Scotland, James I to James VII. In 1603 James VI inherited England as James I and commissioned the translation that still carries his name.
- Alexanderal-ig-ZAN-derScotland
Three kings of Scotland in the twelfth and thirteenth centuries and three Russian tsars — and, long before either, Alexander III of Macedon.
- LouisLOO-issFrance
The French royal name above all others. The numbering ran as far as Louis XVIII, although Louis XVII never reigned, and Louis XIV's seventy-two years is the longest reign of any European sovereign.
- Felipefeh-LEE-pehSpain
Spain's reigning king is Felipe VI, on the throne since 2014. France had six kings called Philippe as well; the name has been royal in two countries at once for centuries.
- FrederikFREDH-rekDenmark
Denmark alternated Frederik and Christian for four hundred years. Margrethe II broke the sequence in 1972 and her son restored it as Frederik X in January 2024.
- ChristianKRIS-chunDenmark
The other half of that alternation: ten kings of Denmark have reigned as Christian, and the current heir to the throne carries it.
- MagnusMAG-nusNorway
Seven kings of Norway, Magnus I to Magnus VII, with Swedish and Danish bearers besides. It has never been an English royal name.
- HaraldHAH-raldNorway
Harald Fairhair is traditionally credited with pulling Norway into one kingdom in the late ninth century; Harald V has reigned there since 1991.
- GustavGUUS-tavSweden
Six kings of Sweden. The first, Gustav Vasa, was elected on 6 June 1523, which is why that is the Swedish national day.
- ErikEH-rikSweden
A Swedish throne name with a fictitious pedigree: when Erik XIV took the crown in 1560 he numbered himself from a list of earlier Eriks that a sixteenth-century historian had largely invented.
- Afonsouh-FON-sooPortugal
Afonso Henriques styled himself Portugal's first king after Ourique in 1139. Five more Afonsos followed, down to Afonso VI in the seventeenth century.
- Joãozhoo-OWNGPortugal
Six kings of Portugal. João VI fled Napoleon in 1807 and became the only European monarch to govern his empire from the Americas.
- Duartedoo-AR-tuhPortugal
Royal in exactly one country and only once: Duarte I, 1433 to 1438. It is Portuguese for Edward, and he was named for his English great-grandfather Edward III.
- Kazimierzkah-ZHEE-myeshPoland
Kazimierz III is the only monarch in Polish history whom Poles call the Great. The name went on serving the Jagiellonian dynasty for two centuries after him.
- Kamehamehakah-MEH-hah-MEH-hahHawaii
Five kings of Hawaii, Kamehameha I to V. The first had unified the islands by 1810, and in Hawaii the name is still read as a claim rather than a style choice.
- CyrusSY-russPersia
Cyrus II built the Achaemenid empire out of a small kingdom in Fars from about 559 BC. Darius and Xerxes inherited the same throne.
- Mehmetmeh-METOttoman
The Ottoman throne name. Mehmed II took Constantinople in 1453, and the last sultan of all, deposed in 1922, was a Mehmed too.
- HaileHIGH-layEthiopia
Tafari Makonnen was crowned emperor of Ethiopia on 2 November 1930 as Haile Selassie I, and was the last man to hold that throne.
Getting the counts right, and choosing between crowns
Royal-name lists go wrong in the same place every time: the arithmetic. William is four kings of England and Britain, not six, and the fifth is currently the Prince of Wales. Edward is eight numbered kings but eleven men if you count the Anglo-Saxons the medieval heralds declined to number. Louis reached XVIII without eighteen reigns, because the boy who would have been Louis XVII died in the Temple prison and never ruled. If you are not certain of a figure, name the country and the highest numeral instead — "the Norwegian line ran to Magnus VII" is checkable, and "a long line of" is honest.
The second thing worth knowing is that royal in one place is not royal everywhere. Duarte is simply Portuguese for Edward, and Portugal used it for a single five-year reign; in England the same name ran for six centuries. Magnus is Norwegian and Swedish and was never English, and it began as a misunderstanding — Snorri Sturluson's account has the first Magnus named after Charlemagne, Karla-Magnús, by a skald who took the Latin epithet for a personal name. Kamehameha is the sharpest case: a Hawaiian dynastic name that is not available as a decorative pick, because in Hawaii it belongs to the monarchy, a holiday and a school.
As choices, these are the safest heavyweight names on the site. They are familiar, they spell one way, and they arrive with nicknames pre-fitted — Will, Harry, Ed, Charlie, Jamie. The risk is not grandeur but frequency: Henry, James and Charles are all in current American use, and one classroom may hold several. If you want the weight without the crowd, cross a border and take the same name from another kingdom — Felipe rather than Philip, João rather than John, Kazimierz rather than any of them.
