"Today we'll learn about the Picts". I went to school in Iceland, they taught us a lot of Icelandic history and only allocated one week to 600 years of legalised slavery.
People were not property in Iceland, but, if you didn't have enough land to support something like 3 cows you were forced to go into service of a farmer for a year. During that year you could leave and die, go to another farm and hope they have food for you or die or swap and get beaten up for not working all waking hours and only maybe die.
The church backed the people up when Iceland was Catholic but with protestantism land was transferred to Denmark and then leased to the farm-archy (agrarchy?).
Iceland was poorer than Romania 120 years ago because fishing villages were illegal. All fishing was property of the farmer that was the current master of the person. They also made law that banned people from getting married without permission of the farmer and supposedly there was a lot of gay sex back then.
