You're about to listen to a BBC podcast, but this is about something else you might enjoy.

My name's Katie Lecky and I'm an assistant commissioner for on demand music on BBC Sounds.

The BBC has an incredible musical heritage and culture and as a music lover, I love being part of that.

With music on sounds, we offer collections and mixes for everything, from workouts to

helping you nod off, boogie in your kitchen, or even just a moment of calm. And they're all put

together by people who know their stuff. So if you want some expertly curated music in your life,

check out BBC Sounds. Hello, I'm Margaret McMillan, and in my Rees lectures, I'm exploring the relationship

between humanity and war.

In the fourth podcast in this series, I'm looking at the age-old conundrum of how do we control

war, how do we set rules for it, how do we try and end it, and how perhaps do we try and

abolish it?

Welcome to Stormont in Belfast. This is the home of the devolved government of Northern Ireland,

although there hasn't been an administration for a year and

a half now. But it was here that the Good Friday Agreement was signed in 1998 after 30 years of

conflict, often referred to as the troubles. And that violence left more than 3,600 people dead

and thousands more injured. This is the fourth out of five of Professor Margaret

McMillan's wreath lectures in her series called The Mark of Kane. And she's been addressing

the impact of war on humanity and exploring the complex relationship between war, culture,

and the citizen. Now she's going to be assessing how the law and international agreements have attempted to address

conflict. Can war really ever be managed? Her lecture is called Managing the Unmanageable. Please

welcome the 2018 BBC Reith Lecturer, Professor Margaret McMillan.

Thank you. BBC wreath lecturer Professor Margaret McMillan. I want to start by talking about someone that you will probably most of you know, and that is Betty Williams.
