Request: The Importance of Leadership in Time of Strife

Hello. People. With talent.

Can anyone recommend any good material about ‘The Importance of Leadership in Time of Strife’? I need some sort of material to base it an essay on. It could anything from a short film, to poetry, to a short story, to a novel. Something. It can even be fiction or non-fiction. Preferably to do with war, although not necessarily.

Please. I know there are some stuff out there, and I just need to look for it. If anyone has any suggestions, even a some that may be vaguely related, then just shout it out.

Thanks! You people have always stood up for me.
