Just finished this fascinating listen on the history of Plantagenet kings of England by Dan Jones.
So much of not just English history but also world history originated during this time - from Magna Carta to Parliaments, to the basic idea that those who are in power have a responsibility to the people they govern.
Would definitely recommend - https://www.audible.co.uk/pd/The-Plantagenets-The-Kings-Who-Made-England-Audiobook/0008363056
