Roman numerals – a little bit of history

Roman numerals are strictly connected with Rome – the special form between a country and a state, that is the city-state. The first versions of Roman numerals appeared when Rome was founded.

There are mostly 2 systems, which are considered previous versions of Roman numerals. They are Etruscan numerals and Early Roman numerals. We can say these 2 systems are the base of Roman numerals.

There is no confirmed year in which Roman numerals were started using. But there are sources thanks nowadays we know for sure that Roman numerals were used years ago.

And one of the sources like that is the Colosseum. This monument was constructed in CE 72-80. It is not preserved in pristine condition but numbered entrances survived. To be more precise, the entrances from XXIII (23) to LIIII (54).

Though Roman numerals were used years ago, it doesn’t mean that they are currently not used at all. And we don’t talk only about math or history classes. Roman numerals you can also see on clocks, even produced these days, or murals. Roman numerals are a popular theme in tattoos too.

And that’s why we created the Roman numerals converter.

Roman numerals – how do they look?

Despite being used nowadays, Roman numerals can be quite complicated for some people at first sight. Why? Because they are not defined as numbers (values) but as dedicated symbols (sometimes described as letters).

What are the basic symbols of Roman numerals? See the chart down below.

















With these symbols, it is possible to create other values, like 4, 9, or 15. They will look as follows:

  • 4 = IV (formerly IIII);
  • 9 = IX;
  • 15 = XV.

The bigger numbers, for instance, like years in Roman numerals, look like this:

  • 1985 = MCMLXXXV;
  • 2002 = MMII;
  • 2020 = MMXX.

And now you see clearly that the Roman numerals can be problematic to convert. But… It doesn’t have to look like that anymore.
