‘When in Rome, do as the Romans do’ – Origin, Meaning, Expansion and Significance

Origin of the phrase.

This phrase derives from a medieval Latin phrase which is attributed to St Ambrose. The original Latin is, ‘si fueris Romae, Romano vivito more’ which means, ‘if you are in Rome, then live in the Roman manner’.

St Ambrose was the bishop of Milan and he lived in the fourth century AD. He wrote this proverb in 387 AD.


The phrase ‘when in Rome, do as the Romans do’ means that ‘when you are living in, or visiting, a community of people, you should follow the laws and customs of that community’.

Literally, the proverb means that when you are in Rome, you should act like the Romans. However, in broader sense, it signifies that ‘whatever country we are in, we should act like the locals’.

Thus, though in the original phrase, St Ambrose referred specifically to Rome, the proverb is most usually used in a more general sense. It refers to the fact that, ‘no matter where in the world we are, we should respect local laws and customs’. In fact, St Ambrose added on a little extra to his proverb, noting that ‘and when I am elsewhere, I act according to other customs’.

However, the proverb also has a more general moral sense. It is polite and respectful to observe local customs and do as locals do. It demonstrates a ‘willingness to learn about others’ way of life and to see things from their point of view, and a respect for that viewpoint too‘.

Thus, in essence, the proverb ‘when in Rome, do as the Romans do’ is all about:

  • Respecting other people’s ways of life.
  • Learning about other cultures.
  • Not imposing one’s own beliefs and habits on others.
  • Respecting local laws.
  • Integrating oneself into another society.

The proverb has yet another meaning. It also means that ‘a novice or beginner should learn and follow the person who has expertise in that particular field’.


It is fascinating that Ancient Rome has been a vehicle for metaphor in this proverb. This suggests the enduring power of Roman civilization in human culture today.

‘Do as the Romans do’ can mean following local laws, integrating with local culture, or learning the language. It is essential to follow local laws when abroad.

Following the local culture when abroad is a mark of respect and has many benefits. Integrating with other cultures expands our minds. Integrating with locals is a great way to make friends. It is a good way to learn about local life. It is polite to respect other cultures.

Living by the idea of ‘when in Rome, do as the Romans do’ enables us to acknowledge that we should not think that we are ‘right’ and other cultures are wrong about these things.

2. Learning: When we promise ourselves that we will act as the locals do when we visit other communities, we open ourselves up to a great learning experience. Acting as other people act helps us to empathize with them and to understand their way of viewing the world. This is a great way to attain wise new ideas, to learn helpful habits, and to get a different perspective on life.

7. Practical: When visiting a different country or region of the world, it is often very practical to act in the same way as locals do. In some very hot countries, for instance, locals sleep during the middle of the day to avoid getting caught in the sun.
