Did The Romans Invade Ireland?

The Romans didn't invade Ireland.
They are said to have had plans to do so but didn't go ahead.
They probably had trade alliances and social contacts with Ireland. It is very unlikely that some Irish mercenaries did not fight with the Roman army.
Given the close proximity between Britain and Ireland the Romans and Irish probably had a good knowledge of each other. Possibly the Roman administrators and military personell had reasons for not pushing their influences into Ireland on a scale parallelled elsewhere.

The culture, laws and traditions in Ireland remained untouched by Roman influences as did their religion. Ireland remained in the 'Iron Age' until around 450-500AD and their Druids remained influential until the advent of established Christianty in Ireland.

No the Celts living there scared them off the idea, same with Scotland but instead of the Celts they had the Pict's to deal with

St. Patrick was a Roman citizen that Irish slavers had kidnapped. So thats activity between the Irish and Romans.

There is no evidence to sugest tht the Romans inavded Ireland.

Unlike the rest of the British Isles ( apart from the North of Scotland), Ireland has no archaelogical remains ascribed to the Roman period, nor any evidence for Roamn influence.

It is more likely that Roman Traders visited Ireland and exchanged the resouces Ireland had available for export. Intermarriage betwee the native Irish and the peoples of the Roman Empire probably took place, if only on a small scale.

A burial in Ireland revealed the body of a women dressed in clothes which were described as in the Roman style. It is thought that she may have been the wife of an indiginous Irish man or the wife of a Roman trader who had settled in Ireland.
Artefacts rom the Roman period were found deposited at Newgrange the pre-historic monument in Meath. These may have been imported from Britain or elsewhere.

Yes and No, because the Slavers and Deserters attempted the Slavers captured some Irish and Deserters fought Irish, and most of the time failed completely, because of tactics Roman soldiers are trained to fight in high numbers therefore not effective while in about 10-50 soldiers while the Irish didn't use many to kill off the invaders/visitors (wrecking up the place) so basically ambush and other Celtic tactics killed off many Romans. The Irish realized they would be slow for nothing if they wore this armor, but some did because it made them feel safer and gave moral to them.

First of all there was an invasion
but there was only one legion ie 100 men this was due to confusion of Ireland's size it was possible it was mixed up with the isle of man then ireland was named hibernia which I think means land of wet and cold which was an excuse not to invade which makes no sense as they tried to invade scotland an even colder wetter region also there was evidence of trade.

And just to throw this in
several irish kingdoms invaded britain after the fall of the roman empire,they were destroyed in wales northern england and Plymouth but completely conquered scotland and f.y.I Scottish in the Scottish language meant irish up to the 17th/18th century.
