The
map
above
shows
where
ethnic
Germans
lived
in
the
borders
of
modern
between
1890
and
1910.
In
many
areas
Germans
made
up
to
95%
of
the
population.
So
what
happened?
To
start
in
1900
there
was
not
Polish
state
and
the
Polish
people
were
split
between
Germany,
Austria-Hungary
and
Russia.
For
more
on
that
process

However,
following
World
War
I
the
Second
Polish
Republic
was
created
with
the
blue
borders
in
blue
above.
And
as
you
can
see
it
more
or
less
corresponded
to
where
ethnic
Poles
lived
at
that
time.
The
Free
City
of
Danzig
is
an
interesting
anomaly.
Although
predominantly German-populated,
the
territory
was
bound
by
the
imposed
union
with
Poland
covering
foreign
policy,
defence, customs,
railways
and
post,
but
remained
distinct
from
both
the
post-war German
Republic and
the
newly
independent Polish
Republic.
However,
World
War
2
would
change
things
again:
Here’s
a
detailed
explanation
of
what
happened
to
Poland’s
territory
and
people
from
the
outbreak
of
World
War
II
(1939)
through
the
shifting
of
its
borders
after
World
War
II
(1945):
September
1939
–
The
Invasion
and
Partition
of
Poland
-
September
1,
1939:
Nazi
Germany
invaded
Poland
from
the
west,
initiating
WWII. -
September
17,
1939:
The
Soviet
Union
invaded
from
the
east,
in
accordance
with
the
secret
clauses
of
the
Molotov-Ribbentrop
Pact,
which
divided
Poland
into
two
spheres
of
influence. -
Poland
ceased
to
exist
as
an
independent
nation,
partitioned
between:-
Western
and
Central
Poland:
Annexed
by
Nazi
Germany,
incorporated
into
Germany
directly,
or
administered
under
harsh
occupation
policies
(General
Government). -
Eastern
Poland:
Occupied
and
annexed
by
the
Soviet
Union,
incorporated
into
the
Ukrainian
and
Belarusian
Soviet
Socialist
Republics.
-
Poland
Under
Occupation
(1939–1945)
-
Nazi-occupied
territory:-
Brutal
policies
aimed
at
cultural
destruction,
economic
exploitation,
and
Germanization. -
Mass
extermination:
Holocaust
resulted
in
the
murder
of
approximately
3
million
Polish
Jews
and
millions
of
non-Jewish
Poles. -
Polish
elites
(intellectuals,
politicians,
religious
leaders)
systematically
targeted
and
killed
or
imprisoned.
-
Brutal
-
Soviet-occupied
territory
(1939–1941,
1944–1945):-
Deportations:
Over
1
million
Poles
forcibly
deported
to
Siberia,
Kazakhstan,
and
remote
regions
of
the
USSR. -
Mass
executions
(most
notably
the
Katyn
Massacre
(1940)):
Approximately
22,000
Polish
officers,
intellectuals,
and
civil
servants
were
executed
by
the
NKVD. -
Sovietization
policies
implemented,
repressing
Polish
culture
and
religion.
-
Deportations:
-
1941–1944:
After
Operation
Barbarossa
(the
German
invasion
of
the
Soviet
Union
in
June
1941),
all
of
pre-war
Poland
was
under
Nazi
occupation
until
Soviet
forces
gradually
recaptured
it
(1944–1945).
End
of
WWII
and
Movement
of
Borders
(1945)
-
As
WWII
ended,
Poland’s
borders
shifted
dramatically
westward
at
the
insistence
of
the
Allied
powers
(USA,
UK,
USSR),
primarily
under
Soviet
direction. -
Yalta
(February
1945)
and
Potsdam
Conferences
(July–August
1945)
set
the
new
boundaries:-
Eastern
Territories
Lost:
Poland
permanently
lost
substantial
territories
east
of
the
Curzon
Line
(regions
including
Vilnius,
Lviv,
Brest),
which
remained
part
of
the
USSR
(now
Ukraine,
Belarus,
Lithuania). -
Western
Territories
Gained:
Poland
was
compensated
with
former
German
territories
in
the
west,
including
Silesia,
Pomerania,
and
East
Prussia
(cities
such
as
Wrocław/Breslau,
Szczecin/Stettin,
and
Gdańsk/Danzig).
-
-
As
a
result,
the
entire
country
shifted
westward
by
roughly
150–200
kilometres
(90–125
miles).
Population
Movements
and
Consequences
-
Forced
Migrations:
Massive
population
transfers
occurred
to
align
populations
with
the
new
borders:-
Over
2
million
Poles
expelled
from
former
eastern
Poland
(now
USSR
territory). -
Around
6
million
Germans
forcibly
expelled
or
fled
from
new
Polish
territories
to
Germany. -
Approximately
1.5
million
Poles
from
central
Poland
and
other
parts
resettled
in
the
newly
acquired
western
territories.
-
Over
-
Poland’s
ethnic
makeup
dramatically
changed:-
Pre-war
Poland
was
diverse
(Poles,
Jews,
Ukrainians,
Belarusians,
Germans,
Lithuanians,
and
others). -
After
WWII,
it
became
overwhelmingly
ethnically
Polish
(over
90%)
due
to
genocide,
expulsions,
migrations,
and
territorial
changes.
-
Pre-war
Political
Aftermath
-
Poland
emerged
from
WWII
greatly
diminished
demographically
(over
6
million
deaths,
including
about
half
the
pre-war
Jewish
population). -
Politically,
Poland
became
a
Soviet
satellite
state,
governed
by
a
communist
government
installed
by
the
Soviet
Union,
which
remained
until
1989. -
The
German
population
which
had
lived
in
what
is
now
Western
Poland
were
expelled
to
make
room
for
the
Poles
who
were
themselves
expelled
from
the
Soviet
Union.
