Please answer the following question: Information:  - The First French Empire, was the empire of Napoleon Bonaparte of France and the dominant power in much of continental Europe at the beginning of the 19th century. Its name was a misnomer, as France already had colonies overseas and was short lived compared to the Colonial Empire.  - Charles Percier ( ( al psje ) ; 22 August 1764 -- 5 September 1838 ) was a neoclassical French architect , interior decorator and designer , who worked in a close partnership with Pierre François Léonard Fontaine , originally his friend from student days . For work undertaken from 1794 onward , trying to ascribe conceptions or details to one or other of them is fruitless ; it is impossible to disentangle their cooperative efforts in this fashion . Together , Percier and Fontaine were inventors and major proponents of the rich , grand , consciously - archaeological versions of neoclassicism we recognise as Directoire style and Empire style . Following Charles Percier 's death in 1838 , Fontaine designed a tomb in their characteristic style in the Pere Lachaise Cemetery . Percier and Fontaine had lived together as well as being colleagues . Fontaine married late in life and after his death in 1853 his body was placed in the same tomb according to his wishes .  - The Empire style, , the second phase of Romanticism, is an early-nineteenth-century design movement in architecture, furniture, other decorative arts, and the visual arts that flourished between 1800 and 1815 during the Consulate and the First French Empire periods, although its life span lasted until the late 1820s (or more in some countries). From France it spread into much of Europe and the United States.     What entity does 'charles percier' has the relation 'country of citizenship' with?
