Do you think we live in hard times?
I highly recommend studying the Britain and Ireland of the mid-to-late 9th century to put things in perspective. Ivar the Boneless has a reputation for being one of the most ruthless Viking sea kings in history. He was fond of torturing Christians and selling them into slavery.
Ivar was a son of Ragnar Lothbrok and a brother of Björn Ironside. He was the leader of the Great Heathen Army that conquered most of England in the 9th century. He was active in Ireland too where he was the king of Dublin which used to be the biggest slave market in Western Europe. The Vikings sold Frankish, English, British and Irish slaves to the Moors in al-Andalus. They also took lots of pretty Irish female slaves to Iceland which is how we got the Icelanders.
In addition to conquering Northumbria and East Anglia, Ivar also conquered the British kingdom of Alt Clud in what is now southern Scotland. If you have ancestors that come from northern England and southern Scotland or Ireland as most Southerners do, they probably had an encounter with Ivar the Boneless and his successors back in the day. The same is true of the southern English who fought off the Great Heathen Army from Wessex and Mercia.
