Origin
Meaning and history of Sigismund
The name Sigismund is of German origin, derived from the Old High German name "Sigimund" which means "victor's protection" or "victorious protector." This name was composed of two elements – "sigu" meaning "victory" and "mund" meaning "protector" or "hand."
The name has been widely used throughout Europe since the Middle Ages. It was particularly popular among the Germanic peoples and later spread to other parts of Europe through royal dynasties and aristocratic families.
One of the earliest recorded uses of the name Sigismund can be found in the Old Norse sagas, where it appears as the name of a legendary Norse king. In the 11th century, the name gained prominence with Sigismund of Burgundy (990-1031), who was a king of the Arles and the Holy Roman Emperor from 1010 to 1027.
Another notable figure bearing this name was Sigismund of Luxembourg (1368-1437), who was the King of Hungary, Croatia, and Germany, as well as the Holy Roman Emperor from 1433 until his death. He is famous for convening the Council of Constance, which aimed to resolve the Western Schism in the Catholic Church.
In the 16th century, Sigismund I the Old (1467-1548) was the King of Poland and Grand Duke of Lithuania. He is credited with strengthening the Polish-Lithuanian Commonwealth and promoting the Renaissance in his domains.
Sigismund III Vasa (1566-1632) was another notable figure, who was the King of Poland and Sweden, and the first monarch of the Polish-Lithuanian Commonwealth after the Union of Lublin. He played a significant role in the Counter-Reformation in Poland and the Polish-Swedish wars.
Sigismund of Sweden (1594-1632), also known as Sigismund III, was the King of Sweden from 1592 to 1599 and the King of Poland and Grand Duke of Lithuania from 1587 to 1632. His reign was marked by conflicts between Protestant and Catholic factions, leading to his deposition from the Swedish throne.

FAQ
Sigismund: questions and answers
How many people in the U.S. are named Sigismund?
Name Census puts the figure at roughly 3 living Americans. We arrive at this by taking every SSA birth registration for Sigismund going back to 1880 and adjusting each cohort for expected survival using CDC actuarial life tables. The result is an age-weighted living-bearer count, not a raw birth total. That works out to about 1 in 114,251,446 US residents.
Is Sigismund a common name?
We classify Sigismund as "Very Rare". It ranks above 4.9% of all first names in the SSA dataset by living bearers. Across the full history of the data, 138 babies have been registered with this name.
When was Sigismund most popular?
The single biggest year for Sigismund was 1920, when 19 babies received the name. The fact that the average living Sigismund is about 101 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
What does the SSA popularity chart show?
The chart tracks births, not the number of people alive with the name today. Each point shows how many babies were given the name Sigismund in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Sigismund a male name?
Yes, 100.0% of people registered as Sigismund in the SSA data are male. You can see the full per-sex comparison in the gender distribution section above, which includes the latest year rank, birth count, and peak year for each sex.
Is Sigismund still being used today?
Yes. The SSA still recorded Sigismund in 2024, and the page above shows its latest-year rank where available. A name can be well past its peak and still remain in steady use, especially if it built up a large population over earlier decades.
Why can a name have a lot of living bearers even if it is not trendy now?
Because living-bearer counts and current baby-name popularity measure different things. A name like Sigismund can build up a very large population over many decades, even if fewer parents are choosing it now than they did at its peak.
Where does this data come from?
First-name figures come from the Social Security Administration's national baby name files, which cover every name on a birth certificate from 1880 to 2024. Living-bearer estimates layer in CDC actuarial life tables broken out by sex to account for mortality. The population baseline (342,754,338) is the Census Bureau's latest national estimate. You can read the full calculation on our methodology page.
Does every first name have Census demographic data?
No. The public Census first-name release only covers names that met the Bureau's publication rules, so many rarer names in the SSA files do not have a published Census demographic snapshot. In those cases, the page still shows the SSA trend, gender history, and state data.
