Unrealized post-war plans and their impact on historical outcomes
Oct 20, 2026
War. The number of armed
and military conflicts that there have been throughout history is
immense. Many of them were caused by the desire
of one side conquering lands from the other.
And even if that wasn't the cause for the war to start,
territorial changes were many times
the consequence of the war.
For instance, in the Franco-Prussian War of 1871, the German Empire
acquired Alsace-Lorraine from France.
After World War I, this same German Empire lost both Alsace-Lorraine
but also all of its colonial lands.
Territorial changes are a big part of military conflicts,
but very often after a war,
there have been proposed territorial changes that ended up
not taking place, either
because they were quickly reverted as a new agreement was reached,
because they were deemed too unfair,
because they didn't have the agreement of all winning parties,
or simply because the losing side refused to keep them.
So in this video, we're going to take a look
at a few of the post-war plans that were never kept,
trying to understand what the world would
look like if they had, and also understand why it was,
they ended up not happening.
First, a Greek and Italian occupation of Turkey.
After World War I, the Ottoman Empire, a member
of the defeated Central Powers, was dismantled,
being reduced to Turkey. Its loss of territories
was established by the Treaty of Lausanne in 1923.
However, before this treaty, a very different one
was signed, the Treaty of Sèvres in 1920.
Through it, the Ottomans would also see its
empire collapse, being divided between the British,
the French and the Italians a little
bit. But the newly established Turkish Republic would
not keep all of its territories in Thrace,
nor all of Anatolia.
Through the Treaty of Sèvres, all islands of the Aegean Sea would
be given to Greece, along with all
of its territory in Europe, with the exception of
Constantinople. Roads would also be granted to Italy,
as well as other territories, along the
southern coast of Anatolia.
The zone of the Straits, which included Constantinople, would
remain Turkish, but under heavy international rule and influence.
Smyrna would initially be
under Greek control, then subject to a referendum,
Armenia would expand its territory tremendously
to include the cities of Trebizond and Erzerum,
and Kurdistan would likely be created,
with a referendum being mandatory for the area.
The terms of this first treaty stirred a lot of
hostility from the Turkish.
In fact, one of the triggers for the Turkish War of Independence
was when the treaty signatories were stripped
of their citizenship by the Grand National Assembly
led by Mustafa Atatürk.
The Turks attained significant victories against the combined
armies of the signatories of the first treaty and in 1923,
the Treaty of Lausanne replaced
the Treaty of Sèvres, ending the conflict
and establishing the Republic of Turkey as
we know it today.
Should the first treaty be put into effect,
Turkey would be a lot smaller today.
Next, a proposed division of Japan.
This plan also existed during the end of World War II,
even though it never took place.
The idea that Japan would be occupied
and divided in the same manner that Germany ended
up being.
The US, Great Britain,
China and the Soviet Union agreed on a potential division of Japan
the Potsdam Conference in July of 1945.
Under the occupation plan that was discussed, Kanto and
Kansai were to be occupied by the US,
Hokkaido and Tohoku by the Soviet Union, Kyushu and Chugoku by
the UK and Shikoku by China,
while Tokyo was to be split 4 ways just as had happened to Berlin.
The US State Department even drew up a plan
for the forces required for each occupation zone.
So, why didn't this happen?
Well, some people say that this plan was intended
for a scenario where a full-scale invasion
of the Japanese archipelago took place
by the Allies. Instead,
the Empire of Japan surrendered to the United States
after the dropping of the two atomic bombs.
The full-scale invasion was no longer needed
and because of this the division
of the occupation wasn't needed as well.
Although another theory is presented
that it wasn't just the dropping of the two bombs that
sped up Japanese surrender,
but also the entry of the Soviet Union in the war and the prospect
of a Soviet invasion, preferring to surrender
to the US in an attempt to preserve some of their
sovereignty and system in the long run than risk
its entire collapse by having to also surrender
to the Soviets. The surrender enabled Japan
to avoid the partition and occupation of the
Japanese home islands. The initial plan for Smyrna
was for it to be under temporary Greek rule and
then have a referendum happen.
One similar situation was the French occupation of the
the Saarland also after World War I. Many
of the examples used in this video refer to post-World
War I and World War II plans.
They are the most recent major conflicts and it's difficult to find
information of this type about older wars,
but if you know of any, let me know in the comments.
Saarland was a region of Germany occupied
and governed by the United Kingdom and France
from 1920 to 1935 under a League of Nations mandate.
It had its own flag, a blue, white,
in black horizontal tricolor,
the blue and white stood for Bavaria and the white and black for
Prussia, out of whose lands the Saar territory was formed,
the French wanted the territory to
be held by them in perpetuity.
And when in 1935 a referendum took place for the people to decide
whether they would remain French or go back to being German,
France campaigned for its permanent
annexation of the territory.
However, they were vastly unsuccessful as over 90% of the people
voted to reunite with Germany
and so the French post-war plan of permanently conquering this part
of Germany did not come to fruition.
After World War II the same situation took place again with
the Saarland being made into a French protectorate from 1946 to 1956.
France even proposed the
creation of an independent Saarland
which would have created a new country in Europe but the
locals rejected it through a vote with 67% being
in support once again to reunify with Germany.
The next example is one I mentioned
in a previous video about Germany's territorial evolution.
After reaching a separate peace
with the Bolshevik Russians due to the Russian Revolution,
Germany would have acquired, through the Peace Treaty of Brest-Litovsk,
a status of protector over the three Baltic nations.
Being victorious in the Eastern Front of World War I, Germany forced
Russia to cede a great part of its territory in Eastern Europe.
According to it, all of Russia-occupied Poland would have
been annexed by Germany, along with Lithuania.
Meanwhile, Latvia and Estonia,
in the map at the time called Livonia, would have become
their own states, but existing as protectorates of the German Empire.
Because Germany lost the war in the Western Front,
this treaty ended up not being implemented
and Germany's expansion into Poland and the Baltic was stopped.
Another unkept plan was another proposed division of Germany itself.
As we know, post-WWII Germany was in fact divided into East
and West, but there was
a different idea previously thought of.
Morgenthau Plan. It was first proposed
by United States Secretary of the Treasury,
Henry Morgenthau, from which it got its name.
Winston Churchill was initially very much
against it, but on the Second Quebec Conference in September of 1944,
US President Franklin D.
Roosevelt and Henry Morgenthau persuaded Churchill
to agree to the plan, likely using a $6 billion
Lindley's agreement to do so.
The plan itself had one main objective, to completely eliminate
Germany's military capacity, and to achieve it,
it proposed, among other things, the following
territorial reorganization.
Germany would lose all its eastern territories to Poland and the USSR,
as in part it did, some northern territory would go to Denmark,
and the Saarland would once again
be given to France. An international zone would be created,
here depicted in green, which would
include most of the Rhineland, the Ruhr region,
highly industrialized, and according to the
memorandum, the heart of German industrial power.
Two German states would be created,
one in the south, made up of Baden-Württemberg and Bavaria,
and another in the north. Eventually,
the plan was deemed unrealistic
and impractical by the Americans themselves, and so it wasn't
followed. One post-war plan that never happened,
although it was supposed to, as opposed to other
ones that weren't applied because of their proponents giving up,
was the return of Olivenza
from Spain to Portugal. Olivenza is a small municipality
on the Portuguese-Spanish border.
it was under Portuguese sovereignty almost always
since 1297 up until 1801 when it was occupied by
Spain during the War of the Oranges
and ceded that year under the Treaty of Badajoz. However,
this treaty was later revoked through the 1850 Treaty
of Vienna in which it was stipulated and
agreed upon by both parties that Olivenza would
be returned to the Portuguese. However, this return
never took place and today the territory remains under Spanish rule.
The Portuguese don't officially
recognize it but have effectively let go of the land
and implicitly accepted Spanish sovereignty
over it.
And finally, one more plan that didn't,
at least to its fullest extent, take place
after World War II was the proposed annexation
of German territories by the Netherlands.
At the end of World War II,
plans were made in the Netherlands to annex German territory
as a compensation for the damages caused by the war,
through what became known as the
Bakker Schut Plan. In its most ambitious form,
this plan included the cities of Cologne, Aachen,
Münster and Osnabrück
and would have enlarged the country's European territory by 30 to 50%.
The local population would have to either be deported or,
when still speaking the original
German dialects, be Dutchified.
There were three plans with the same idea, A, B and C, each with
different areas being annexed
and each with less ambition than the one before. The plan was
eventually abandoned after the US rejected it,
eventually a much smaller area of around 70
square kilometers was allocated to the Netherlands,
almost all of it being returned to West Germany in
1963 after they paid the Netherlands 280 million German marks.
So, those are some of the post-war
plans that were never kept regarding territorial changes,
from treaties that were replaced by other
treaties, to temporary situations that could've been made permanent,
to full-on planned divisions
or occupations of entire countries that ended up not taking place
or taking place in a different
manner. Are there any other interesting post-war plans
that were proposed but then never followed?
