On 25 February 1757, Burke signed a contract with Robert Dodsley to write a "history of England from the time of Julius Caesar to the end of the reign of Queen Anne", its length being eighty quarto sheets (640 pages), nearly 400,000 words. It was to be submitted for publication by Christmas 1758. Burke completed the work to the year 1216 and stopped; it was not published until after Burke's death, being included in an 1812 collection of his works, entitled An Essay Towards an Abridgement of the English History. G. M. Young did not value Burke's history and claimed that it was "demonstrably a translation from the French". Lord Acton, on commenting on the story that Burke stopped his history because David Hume published his, said "it is ever to be regretted that the reverse did not occur".
When was Burke's history of England published?

During the 20th century, many artists immigrated to Mexico City from different regions of Mexico, such as Leopoldo Mendez, an engraver from Veracruz, who supported the creation of the socialist Taller de la Grafica Popular (Popular Graphics Workshop), designed to help blue-collar workers find a venue to express their art. Other painters came from abroad, such as Catalan painter Remedios Varo and other Spanish and Jewish exiles. It was in the second half of the 20th century that the artistic movement began to drift apart from the Revolutionary theme. Jose Luis Cuevas opted for a modernist style in contrast to the muralist movement associated with social politics.

The Russians sent a fleet to Sinop in northern Anatolia. In the Battle of Sinop on 30 November 1853 they destroyed a patrol squadron of Ottoman frigates and corvettes while they were anchored in port. Public opinion in the UK and France was outraged and demanded war. Sinop provided the United Kingdom and France with the casus belli ("cause for war") for declaring war against Russia. On 28 March 1854, after Russia ignored an Anglo-French ultimatum to withdraw from the Danubian Principalities, the UK and France formally declared war.
