Ethnic Germans Living Within The Borders Of Modern Poland In 1900 – Brilliant Maps

Ethnic Germans Living Within The Borders Of Modern Poland Between 1890 & 1910

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

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.

  • 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.

  • 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.
  • 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.


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.
