The Luxembourg Coup of 1856, also called the Putsch of 1856, is a reactionary revision of Luxembourg's constitution on November 27, 1856.
While not a true coup d'état or revolution, its detractors dub it a 'royal coup', as the reigning Grand Duke of Luxembourg, William III, greatly expands his powers, and the name will stick.
Aimed at reversing the liberal successes embodied in the 1848 constitution, the major changes enacted by William will be undone with the promulgation of a new constitution in 1868, after the Luxembourg Crisis.
However, some changes, such as the creation of the Council of State, will last.
