WW I

With each century we've talked about in this course, I've had a general theme.  The 16th and 17th centuries: a time of particularly rapid change.  The 18th century: the age of reason.  The 19th century: the age of progress.  For the 20th century, there are lots of possible themes, but perhaps the single most striking characteristic of the 20th century was that it was an age of violence--much of it senseless violence.  A good example of this, World War I.

World War I, as the name implies, was a war that involved much of the world.  It was, however, primarily a European war, and it was the Europeans who started it.  How did this happen?  How did the best educated, most civilized people in the history of mankind start one of the most terrible, most senseless wars in history?

Now, often enough, people want to blame Germany for both World War I and World War II.  It's wrong, though, to view the Germans as the sole people responsible for these disasters.  Nevertheless, it is easiest to understand World War I and its causes as a result of a series of German mistakes.

Germany did not become a nation until after the France Prussian war of 1870.  Once Germany did unify, however, it was time for the rest of the world to look out.  Germany was soon a leader in vaccines, in chemistry, and in all sorts of other areas.  It was rapidly catching Britain as a leading industrial power.  However, because Germany unified so late, it missed out on much of the European scramble for colonies around the world.  Having colonies seemed critical to an industrialized society.  Such colonies guaranteed access to key industrial materials, and guaranteed markets for manufactured goods.  France, Britain, and even little European countries like Belgium and Portugal had colonies throughout the world.  The German attitude was that, if there was any part of the world *not* already claimed by another European country, that should be theirs: they didn't yet have their fair share of colonies.  German belligerence ended up alienating many other countries, and, by 1914, Germany had only one reliable ally left in Europe: Austria.

German aggression, then, did in part creating the tensions that led to World War I.  But playing an even bigger role, German fear of aggression. 

Germany, for instance, was afraid that Britain might decide to side with Germany's enemies.  Was this likely?  Well, not really.  The English speaking peoples and the German speaking peoples were natural allies, sharing a common historic enemy in France.  But Germany wanted to make sure Britain never attacked them, and so they created a strategy based on the "Risk Theory."  The Risk Theory was the idea that, if Germany built a big battle fleet, Britain couldn't afford to ever attack them.  The British might wind, but they would lose so many ships that their world-wide empire would be endangered.  So Germany builds its battle fleet.  But when Britain learns of this, it makes the British mad--and makes them more likely to attack Germany!  What could be more senseless than to adopt an idea to *prevent* war with another nation that actually makes war with that nation more likely?

While the Germans worried somewhat about Britain, they were far more concerned about two other potential enemies, France and Russia.  The Germans were certain that they could lick France alone, and they were pretty sure they could defeat the Russians.  The nightmare, however, was the two-front war, having to deal with the French in the West and the Russians in the East at the same time. 

The Germans came up with a plan for the two-front war: the Schlieffen Plan.  Basically, this plan said that, in the event of war, Germany would begin by attacking France with all its might, trying to knock France out of the war quickly.  Then the Germans would shift all their men and material to the eastern front to deal with the more serious threat posed by Russia.  The Germans thought they'd do OK with this plan. Russia, while formidible, was a vast country, slow to mobilize.  While the Russians were getting their act together, the Germans were sure they'd have time to put France out of business.

Two problems, though.  First of all, the Schlieffen Plan depended on speed, and the German/French border is not built for speed: mountain country.  So--an easier route: right through Belgium.  The Germans don't seem to have thought this a problem.  Why would the Belgians not let the Germans march right through the country?  Also, the Schlieffen plan was the only plan the Germans made.  They adopted the plan in 1905, never revised it, and never made any other plan.  All of this meant that Europe was a powder keg waiting to explode.

The spark came in a region of Europe known as the Balkans.  For a long time, the Balkans had been part of the Ottoman Turkish Empire.  The "Sick Man of Europe" was still around at this point, but nearing death, and the great question, as always: what would become of the territories of the empire once collapse was complete?

Some would have thought it made no difference.  Otto von Bismarck has said that the whole of the Balkans wasn't worth the bones of a single Pomeranian grenadier.  But others felt differently.  Various national groups in the Balkans wanted independence.  Austria wanted parts of the Balkans for their own empire.  The Turks likewise wanted to hold on to as much territory as they could.

Little by little, some of the nationalist groups got their way.  Slavs, for instance, managed to create the nation of Serbia, while the Bulgars created Bulgaria.  But Austria too took some of what it wanted: Bosnia and Herzegovina, for instance.  This was territory with a large Slavic population, the Serbs thought it ought to be theirs instead of Austria's.  But Serbia was no match militarily for Austria, so the Serbs resorted to terrorism.  Groups like the Black Hand used bombing and assassination to destabilize the region and drive Austria out.  The terror campaign reached its height when a Serbian-backed terrorist assassinated Franz Ferdinand, the heir to the Austrian throne, and his wife. 

The Austrians were furious, and it's not too surprising that such an event would lead to war between Austria and Serbia.  But what happens next?  Austria would have won easily against Serbia alone.  But the Russians, big  brothers to all other Slavs, would certainly come to Serbia's aid.  And then the shoe would be on the other foot: Austria would get crushed.  But Germany could not stand by and see their only ally defeated, so the Germans stepped in to help the Austrians.  However, the Germans had only one plan for war: the Schlieffen plan.  Attack France first!  And, to get there in a hurry, go through Belgium.  German invasion of Belgium brought Britain into the war as well.  In 1915, Bulgaria joined the war on the side of the "Central Powers" (Germany, Austria, Turkey), while Italy joined on the side of the allied powers (Britain, France, Russia, Serbia).  Because these nations had colonies all over the world, they drew on the resources of those colonies, and we ended up with a conflict that affected and involved much of the world--all stemming from one assassination in the Balkans!

As it turned out, the Schlieffen Plan didn't quite work.  The Belgian King said, "Belgium is a country, not a highway," and the Belgians, while they couldn't stop Germany, slowed the German forces down just long enough that France and Britain could stop the German invasion.  The Germans got to within 50 miles of Paris, but there the attack stopped.  What now?

Well, the Germans improvised, digging themselves into trenches, putting up barbed wire, and trying to hold on to what they had already taken.  The British and French on the other side did the same thing, digging trenches and putting up defenses designed to stop any potential German advance.

This led to four bloody years of trench warfare, with neither side able to make progress, and both sides losing thousands of men.  The twin battles of Verdun and the Somme, for instance, cost the lives of 1,000,000 men--and all that happened was the exchange of a few miles of territory.  Nothing--not poison gas, not airplanes--could break the stalemate of the trenches.  And yet instead of making peace, the diplomats back home just let the war drag on and on while a whole generation of young men was lost.

Here's a graphic showing the "progress" made during four years of Trench Warfare:

Even more senseless than the fighting in the trenches, what happened in Armenia.

Armenia is an area along the northeast side of the Turkish empire on the border with Russia.  It had long been part of the Turkish empire, but, while the Turks were Muslims, the Armenians were Christians.  The Turks worried that the Armenians might side with the Russians, and they asked the Armenian community leaders for a sign of their loyalty.  The asked the Armenians to surrender their weapons to show they didn't intend to fight alongside the Russians.  For the most part, the Armenians complied. 

They couldn't have made a more foolish or more horrible mistake, because, once the Armenians had given up their weapons, the Turks set about the first (but unfortunately not the last) attempt at genocide in the 20th century.

Here's a summary from one writer:
It is difficult to convey the horror of the events of 1915, as the Ottoman government set into action its design for genocide.  In April 1915, The Armenian intellectual and community leaders in Istanbul were rounded up and transported in ships to their doom: among the victims were a number of priests, poets, doctors, and the great composer Komitas.  Able-bodied Armenian males through out the Ottoman empire had already been rounded up into labor battalions, though not issued with arms.  They did sterling work for the Ottoman army and built many roads and railways.  They were now set upon by the Turkish units and shot down or bludgeoned to death almost to the last man.
With their young men, their leaders, and most of their weapons gone, the Armenians were mostly defenseless.  Here's what happens next:

Even more tragic and horrible was the fate reserved for the Armenian civil population.  Infants were forcibly removed from their families to “orphanages“ which turned out to be pits dug in the ground, into which the children were hurled alive, to be covered up with piles of stones.  Women and old people were formed up into caravans and forced to march on foot for hundreds of miles towards Aleppo and other concentration points in Syria.  On the way, they were waylaid by bands of ruffians, who were given carte blanche by the government to kill deportees and steal their possessions.  Neither food nor water was provided to the deportees. Who soon went mad and died of thirst.  In the night-time, the gendarme escorts would amuse themselves by stripping any good-looking girls who took their fancy and forcing them to indulge in various forms of sexual perversion.  These usually ended with the victims being disemboweled, and their breasts sliced off.  Many such corpses were thrown into the Tigris and Euphrates and washed up in town farther downstream.
A different source describes in detail what happened in individual cities and towns.  Here's an example:
For a few weeks, there was peace, and an end to oppression throughout the district.  But at the end of June, a determined assault was made against the whole region… In Moush itself, in early July, the mood changed to one of the most dire oppression: further exactions were made, and demands for arms; moreover leading Armenians of the towns and villages were subjected to frightful tortures—fingernails pulled out, limbs twisted, teeth knocked out, noses beaten-down; and wives and daughters were raped in public before their broken menfolk. In Moush itself the men resisted for four days from the stone-built houses and churches, before going down fighting.  For the women and children, a grimmer death followed: they were driven out of the city into specially prepared large wooden sheds in the nearby Armenian villages; these were then set on fire, and amid scenes of horror, and the vilest, most sadistic brutality from the Turkish guards, the defenseless woman and children were all burnt to death.
Ultimately, the Turks wiped out about 1 1/2 million Armenians, about half the population of the region.  What makes this all the more senseless is the fact that the Turks had to divert manpower to carry out the genocide.  They should have been focusing (say) on stopping the British forces under Allenby from marching into Turkey.  Instead, they were using their men to wipe out their own people.

Some years later, when Adolf Hitler was about to invade Poland, he apparently was convinced that any atrocities his men committed would be soon forgotten.  Here's how Wikipedia quotes his speech:

Our strength lies in our quickness and in our brutality; Genghis Khan has sent millions of women and children into death knowingly and with a light heart. History sees in him only the great founder of States. As to what the weak Western European civilisation asserts about me, that is of no account. I have given the command and I shall shoot everyone who utters one word of criticism, for the goal to be obtained in the war is not that of reaching certain lines but of physically demolishing the opponent. And so for the present only in the East I have put my death-head formations' in place with the command relentlessly and without compassion to send into death many women and children of Polish origin and language. Only thus we can gain the living space (lebensraum) that we need. Who after all is today speaking about the destruction of the Armenians?
We generally summarize this to, "Who remembers the Armenians?"  It's a short-hand way of noting that, often, the great atrocities of history are forgotten, and the perpetrators never held to account.  A terrible precedent.

While we generally seem to focus on the Western Front in World War I, fighting along the Eastern Front was, if anything, worse.  The Russians alone lost eight million men killed, captured, or wounded.  Finally, torn apart by Revolution at home, the Russians gave up. Lenin, the Communist dictator who in November seized control of Russia, basically surrendered unconditionally, signing the treaty of Brest-Litovsk.  This treaty let the Germans annex territory that included prime agricultural land and many of Russia's most important industrial resources.

This was a huge shot-in-the arm for Germany.  All sorts of extra food to feed their soldiers and civilians.  All sorts of iron and coal, raw materials badly needed for the war effort.  And, in addition, Germany no longer had to worry about the two-front war.  The Schlieffen Plan had almost worked in reverse: Russia was out of the war, and now Germany could concentrate all its efforts on the Western front.  Essentially, Germany had won the war: the Germans could have arranged peace terms favorable to Germany.  But instead of negotiating, the Germans fought on.  Why?  Because they had been fighting the war with no military or political objectives.  The difficulty of fighting without objectives is that you don't know what you are fighting for, and so there is really no way to tell when you have won!  And Germany continues to fight a "won" war until, eventually, the war is no longer won.

Ultimately, 1918 was a disaster for the Germans, largely because of American entry into the war.

Now for quite a long time, America avoided entry into the war.  George Washington had warned the US against becoming entangled in European wars, and for 150 years the US had followed Washington’s advice.  Woodrow Wilson (first elected in 1912) and his Secretary of State Bryan were committed to this “non-entanglement” tradition, trying to keep us from getting involved.

But it wasn’t easy.  As the war raged in Europe, tremendous trade opportunities were available to American businesses, and American businessmen took advantage of this.

Germany had resorted to U-boat warfare to try to block supplies from getting to Britain.  They warned us that anyone sailing on a British ship was subject to attack, but Americans continued to travel on British ships anyway.

In 1915, the Germans sunk the Lusitania, killing 1,198 people including 128 Americans.  This didn’t play well with the American public.  On top of that, the British-controlled transatlantic cable was transmitting information designed to make us sympathize with their side and be outraged by German atrocities.

Still, Wilson held the line, and, when he ran for reelection in 1916, he made that a key point in his campaign.  His Republican opponent Charles Evans Hughes (called Charles Evasive Hughes by his detractors) didn’t make clear where he stood on US entry into the war.  The Wilson campaign, however, made much of Wilson’s success in avoiding American involvement.  “He kept us out of war” was a featured slogan.  One campaign ad: “You are working, not fighting; alive and happy, not cannon fodder; Wilson and peace with honor, or Hughes with Roosevelt and war?”

Well, Wilson won reelection, but in a close vote: 277 to 254 in the electoral college.  The American people had chosen Wilson, at least partly on the implied promise we were *not* going to enter the war.

But there were soon problems with this policy.  The papers played up the Zimmerman Note, an intercepted German message to Mexico that said that, in the event of American entry into the war, Mexico should attack the United States.  At the end of the war, the Germans would repay them by getting back for them Texas, New Mexico, and Arizona.

On top of that, the Germans were sinking American ships taking supplies to Britain.  Anti-German sentiment increased, and Wilson decided we had to go to war.  

But if he was going to break his implied campaign promise, Wilson better give the American people good reasons for doing so.  He did.

1.  This would be a “war to end all wars.”
2.  This would be a war to “make the world safe for democracy.”

Good goals—but more than goals.  Wilson was determined that the war would be a “progressive” war, one that did in fact lead to a more peaceful world and that did in fact lead to free and democratic societies.

Wilson suggested a way of settling the war that might have done just that, his “Fourteen Points,” Wilson’s plan for resolving European (and world-wide) problems after the fighting was done.

Wilson’s points included:

1.  Open covenants (no secret diplomacy)
2.  Freedom of the seas
3.  The removal of economic barriers
4.  The reduction of national armaments “to the lowest point consistent with safety”
5.  The impartial adjustment of colonial claims
6.  The evacuation of Russia by foreign armies
7.  Belgian independence
8.  The Alsace-Lorraine area restored to France
9.  Adjustment of the Italian frontier
10.  Autonomy for the peoples of Austria-Hungary
11.  The restoration of Romania, Serbia, and Montenegro
12.   Autonomy for Turkey
13.  An independent Poland
14.  The creation of a League of Nations

Now these ideas reflect a pretty solid understanding of the causes of WWI and a pretty sound recipe for an amicable peace.  American entry into the war *did* turn the tables in Europe leading to the defeat of Germany, and our contributions *should* have meant that we would have an important voice in how the war was actually settled, *especially* since the Germans surrendered under the belief they would be treated in accord with the generous terms promised by Wilson.

But what actually happened is that, after the war was over, the British, and even more the French, insisted on much harsher terms for Germany—and Wilson gave in.  Why?  He sacrificed most of his goals to achieve the one goal he thought most important, the creation of the League of Nations. The Versailles Treaty that actually ended the war (June 28, 1919) stripped Germany of the Saar Basin and the Danzig region, reduced the German army to 100,000 men, forbid German fortifications on their border with France—and imposed on German an indemnity of more than $30 billion to pay for the war.  But Wilson had got his League of Nations—sort of.  And World War I was a victory overall for the good guys—sort of.

But it did not do what Wilson promised.  Instead, World War I led directly and indirectly into the creation of some of the most tyrannical regimes the world has ever seen, and--just 20 years later--to another world war--this time, on an even larger scale.

[Note: if you get the World War I essay, it would be good to note, at least briefly, how WW I contributes to the rise of Communism, Fascism, National Socialism, and, eventually, leads to WW II.  Also note there were five different treaties that ended World War I, all of them bad.  We are still living with the consequences of the failure of the Sevres Treaty, the treaty that dismantled the Turkish empire, for instance.]
