After the Belgian Revolution
in 1830, William I lost control
of Belgium: this included,
under the 1839 Treaty of
London, the French-speaking,
western (Belgian) half of
Luxembourg. He retained the
eastern part, and the Grand
Duchy now assumed its
modern shape. The Dutch
kings William (Guillaume) I,
II and III remained grand

AUTONOMY AND
OCCUPATION
In 1890, William III died
without a male heir. In the
Netherlands, his daughter
Wilhelmina could succeed,
but in Luxembourg, under
the ancient Salic Law of the
Franks, women were not
allowed to inherit the throne.
Instead, a relative, Duke
Adolphe of Nassau-Weilburg,
became grand duke, found-
ing the present dynastic line.
Salic Law was abandoned
by his son, William IV, who
passed on the title to his eld-
est daughter Marie-Adélaïde,
who became Grand Duchess
in 1912. Despite its neutral
status, Luxembourg was
invaded and occupied by the
Germans during World War I.
After the end of the war, in
1919, Marie-Adélaïde abdi-

Charlotte, who ruled as
FOUNDER OF THE EU
Luxembourg is a keen
advocate of international
cooperation. In 1950, it
formed part of the Benelux
Customs Union and in 1957,
it was one of the six found-
ing nations of the European
Economic Community, which
evolved into the European
Union. Today, Luxembourg
City is the location for vari-
ous EU institutions, including
the European Court of Justice
and the European Court of
Auditors. In 1964, Grand
Duchess Charlotte abdicated
in favour of her son Jean,
who had married Princess
Joséphine-Charlotte of
Belgium, thus linking the
two nations. In 2000, Grand
Duke Jean in turn abdicated
in favour of his son Henri.
states agreed to guarantee
Luxembourg’s independence
and neutrality. The Prussians
left Luxembourg City and
their fortress was dismantled.
In the last decades of the 19th
century, Luxembourg began
to prosper by exploiting its
high-quality steel, produced
in the south of the country.

Grand Duchess until 1964.
During her reign, neutral
Luxembourg was again over-
run by the Germans, and in
1942 was formally annexed
to Germany. Conscription,
forced labour and other
oppression inspired a deter-
mined campaign of resistance.
In the bitter winter of 1944–5,
Luxembourg was the scene
of the devastating Ardennes
Offensive (see p231).
