Blockades, u-boats and sinking of the Lusitania | The 20th century | World history | Khan Academy

History is important because it helps us to understand the world, and how it became what we see today. It can help us to solve problems that we face today by seeing the solutions that were tried in the past. We must learn from mistakes that were made before us, so that we do not repeat them.

It's an interesting coincidence that Woodrow Wilson's initials are W.W. as in World War.

[@TheStratfish]

Keep it up Sal & Team! Excellent work as always!

[@ghandiesel]

great series, its bringing me back to high school US History...a good review on my memory

[@Staldren]

I really like learning history.

[@superdau]

Of course they had advanced knowledge. Everyone had it. It's on a timetable. On the date of the medallion: U-boots often followed ships for quite some time. So maybe the chase had already started two days before.

[@TheDuckoe]

These videos are so awesome!

[@Mylitla]

That first quote from William Jennings Bryan eerily foreshadows the even more ironic prediction by Marshal Ferdinand Foch. Who, after the Treaty of Versailles was signed, said "This is not a peace. It is an armistice for twenty years." He was off by 65 days.

[@pronoob1983]

watching every history upload ova here! Thank you Salman Khan :)

[@slyninjutsu07]

I thought Salman Khan was that popular indian actor?

[@PoweredMinecart]

I know it would be ironic for khan because he is somewhat pushing against the classroom - teacher situation, but he would be an epically awesome teacher.

[@ncktyu]

I hope he keeps all these videos saved on his computer in case something bad happens with youtube.

[@HenrikSultan]

Not very fun

[@TheIgnorantbassist]

Those who do not learn history are doomed to repeat it!

[@walterdennisclark]

There's an important feature of the delay of the American entry into the war. Neutrality was not so much a desire for peace, but an indecision as to which side to join. At this time in our history, our culture looked at war somewhat romantically. There was a huge German American population but it did not prevail in the debate as to which side to be on because of one man: George Creel. This is important because it shows that historically we are less and less interested in war.

[@danielahernandez5756]

very good

[@ncktyu]

Yeah

[@hello562826]

more detail

[@hisxmark]

If you want more, you could read a book.

[@kevinstathis1650]

Depends whether you have a life or not

[@pouriajafarikia65]

Wasn't Poland not a thing until 1921?

[@HenggaoCai]

a little bit superficial and shallow

[@TheIgnorantbassist]

Anorexics aren't trying to fight a war. 1000 calories + hard work = very difficult!

[@Menegoth]

Coincidence? I think not!

[@GhostGuy764]

he as so many he'd need terabytes upon terabytes of spave

[@justindixon1577]

is he canadian?

[@davidsweeney111]

The Lusitania you say ?

[@TorchWhoCanada]

America could have stayed out of world war 1, no offense but the war was nearing an end anyway

[@daryna94]

1000 calories is actually not that little... comparing to the anorexics whose calorie intake approximates 400-500 calories. just saying...

[@aljosapiano]

It is well below maintenance level for most men, especially if you are active. Any diet which results in a consistent caloric deficit will impact more than just fat/muscle loss, and as such it is certainly suboptimal to be in it during a time of war.

[@prabhanshukatiyar4635]

As always, america tries to fool people but makes mistakes

[@-thanos-7321]

Titanic!

[@ziontrask3459]

Harry Potter are you the real Harry Potter?
