That's the Irish title. I studied the entire Duolingo module, but that was in 2017-2018. My mother's family comes from Northern Ireland. Mostly Scots-Irish. Not sure if it's that region, but it might be. Either way, in Early Medieval Ireland, these were the hostages and slaves. The O'Neill's were the boorish Australians to the North. Sandwiched between the two O'Neill territories, in fact.
