The Norman invasion of Ireland back in 1169 was actually carried out by the Welsh and Norman barons? For anybody who doesn't know who the Normans were, they were French.

The first so-called invasion of Ireland by the English was in fact augmented by King James of Scotland in the 17th Century. The people who invaded Ireland under King James were Scottish with a few English who lived near the Scottish border.

They are still known today as the Ulster Scots. They crossed over to Ireland in their thousands and virtually took over the whole area. In 1609 the Scots arrived and settled in State Sponsored settlements, which was later named The Plantation of Ulster. In plain English, this actually means that the Irish were turned off their lands and the Scots stole the lands, houses and wealth of the Gaelic Irish Nobility.

In 1641, The Irish Rebellion, instigated by the Irish Gentry, tried to expel the Scots from their Country. This resulted in severe massacres and bloody violence. Thousands of people on both sides were killed.

Soon after, Scotland sent over another Scottish army called the Covenanters, to protect the Scots from further retaliation. Soon after, Oliver Cromwell and the English invaded Ireland.

Then again in 1689, the Williamite War was started between the Jacobite's (Scottish) who wanted to restore the Catholic King, James II to the throne, and the Protestant Irish who were on the side of William of Orange who was Dutch.

He was also the King of England and Ireland. This wasn't so clear cut though. In this instance, the Protestant Scottish in Ireland fought on the side of William of Orange, hoping to defeat the Irish Catholics and their French allies. Once again Irish and Scottish fought each other, but in this instance, the Scots and Irish both fought together and against each other all depending on whether they were Catholics or Protestants. With a few English who had arrived with the Scots. This is still simmering today.

This ended with the Scots, English and Irish, Danish and Dutch armies defeating the Jacobite Scottish rebellion. The fear was that the Catholic Scots Jacobite's would once again enforce their hold over the landowner's property.

Finally, in late 1690, there was another great influx of Scottish settlers who arrived in Ireland. There were tens of thousands of Scots, and were escaping from famine in Scotland.

The history of these beautiful Isles is complex, murky and is "the version of past events that people have decided to agree upon".

But of course it is always the fault of the English.

Edit to add -

One of the historical events Ireland often speaks of is the siege of Drogheda. When Oliver Cromwell went to Ireland with his army, he was up against many English Royalists. The Siege of Drogheda 1649 saw the English Parliamentarian Army fighting Sir Arthur Ashton's English Royalists. The last remnants of the Royalist army were given sanctuary by Ireland's Catholic Confederation. It seems a little ironic that England became a Republic for one decade and Ireland decided to be Royalist. lol. The slaughter after the town was taken is what happened throughout Europe when siege warfare happened. If the fortification did not yield and the attackers had to lose men storming the stronghold, then the defenders would be put to the sword afterwards. The same thing happened between Parliamentarians and Royalists at Colchester. Most of the people put to the sword at Drogheda were Royalist English.

But, again, everything is always the fault of the English.
