Random Historical Event Generator: 200 Events With Date and Place: how it works

Two hundred real events sit behind this random historical event generator, from the building of the Great Pyramid to the pandemic declared in 2020, and each press draws five. Every card gives the date, the place and one line on what happened, so it doubles as a random historical date generator.

From the Great Pyramid to 2020, narrowed three ways

The Era row splits the list by date, from 28 ancient events before the year 500 to 33 since 1946. Two more rows sort by kind and by region, and a draw has to match all three: Invention with 1800 to 1899 leaves seven cards, from the first postage stamp to the first telephone call. More than half of the events took place outside Europe, and every continent has one, Antarctica included.

Play it as a timeline or a quiz

Press Hide all dates, draw five and read the names aloud. The group orders them, then a tap on each card settles it. For a quiz, read the summary and ask for the year. Wars, disasters and assassinations are included, each held to one plain line.

Tips

  • A full date such as October 14, 1066 means both sources gave that day. Where they disagreed, the card keeps only the month or the year.
  • Start the 60-second timer and count how many events a team can place in the right century.
  • Africa in the Region row holds 15 events, from the Great Pyramid to South Africa's 1994 election.

Questions and answers

How were the 200 events checked?

Each line was last checked on September 18, 2026 against the event's encyclopedia article and a second source, usually a day-by-day history calendar. Seven candidates failed that check and were cut, among them the first ARPANET message and the start of work on the Taj Mahal. If a date or a place looks wrong, tell us through the contact page.

Why do some cards say 'by tradition'?

Nobody recorded the day, or the record was written centuries later. The founding of Rome in 753 BC and the first Olympic Games in 776 BC are the years ancient writers settled on, so those cards say so. BC years count down toward year 1, so 490 BC comes before 480 BC, and there is no year zero.

Can I draw a bare date or year from the past instead?

Not here: every card is an event with its date attached. The random date generator draws a day, month and year from any range you set, back to the year 1. The random year generator draws a bare year from 1900 to 2026.

How this list was compiled: Compiled by Random Generator HQ. We chose the 200 events and wrote the lines ourselves, then checked each one on 2026-09-18 against two sources that had to agree on the event and on its date. The place is the one given in the first source. The first source is the event's own English Wikipedia article (https://en.wikipedia.org/). The second is the On This Day page for the event's year (https://www.onthisday.com/events/date/ followed by the year, with bc added for years before year 1). A busy year runs over several pages there, so an event late in the year sits on a later page or on the page for its month, such as https://www.onthisday.com/events/date/1969/july for the Moon landing. On This Day has no usable entry for 14 events, mostly ancient ones, so for those the second source is the World History Encyclopedia article instead: https://www.worldhistory.org/Ashoka_the_Great/, https://www.worldhistory.org/Battle_of_Kadesh/, https://www.worldhistory.org/Battle_of_Red_Cliffs/, https://www.worldhistory.org/Black_Death/, https://www.worldhistory.org/Charles_I_of_England/, https://www.worldhistory.org/Code_of_Hammurabi/, https://www.worldhistory.org/Colosseum/, https://www.worldhistory.org/Genghis_Khan/, https://www.worldhistory.org/Great_Pyramid_of_Giza/, https://www.worldhistory.org/Nicolaus_Copernicus/, https://www.worldhistory.org/Olympic_Games/, https://www.worldhistory.org/Shi_Huangdi/, https://www.worldhistory.org/Third_Punic_War/, https://www.worldhistory.org/hannibal/. Where the two sources gave different days, the line keeps only the month or the year. Where they gave different figures, the line uses a figure both support or leaves the figure out. Dates that rest on tradition or on estimates say so with the words by tradition or about. The smallpox entry was also read against the World Health Organization page https://www.who.int/news-room/spotlight/history-of-vaccination/history-of-smallpox-vaccination. On 2026-09-19 three lines were changed after a second reading of the same sources: the Colosseum line now says about 100 days, the figure both sources support; the founding of Tenochtitlan now says 1325 by tradition, because its article calls the exact date unclear and On This Day calls it legend; and the Good Friday Agreement line was reworded. Events we could not confirm in two sources were left off the list, among them the Edict of Milan, the Battle of Talas, the start of work on the Taj Mahal and the first ARPANET message.
