The Cambridge Modern History is a comprehensive modern history of the world, beginning with the 15th century Age of Discovery, published by the Cambridge University Press in England and also in the United States.

The first series, planned by Lord Acton and edited by him with Stanley Mordaunt Leathes, Sir Adolphus William Ward and G. W. Prothero, was launched in 1902 and totalled fourteen volumes, the last of them being an historical atlas which appeared in 1912. The period covered was from 1450 to 1910. Each volume includes an extensive bibliography.

A second series, with entirely new editors and contributors, The New Cambridge Modern History, appeared in fourteen volumes between 1957 and 1979, again concluding with an atlas. It covered the world from 1450 to 1945.

Planning and publishing

The first discussions about creating The Cambridge Modern History took place in 1896.

The original Cambridge Modern History was planned by Lord Acton, who during 1899 and 1900 gave much of his time to coordinating the project, intended to be a monument of objective, detailed, and collaborative scholarship.'John Emerich Edward Dalberg Acton, 1st Baron Acton (English historian and moralist)', in Encyclopædia Britannica Acton was Regius professor of modern history at Cambridge, and a fellow of All Souls, Oxford. He had previously established the English Historical Review in 1886 and had an exalted reputation.R. C. S. Trahair, From Aristotelian to Reaganomics: a dictionary of eponyms with biographies in the social sciences (1994), p. 5

The new work was published in fourteen volumes between 1902 and 1912, in the British Isles by the Cambridge University Press and in the United States by Macmillan & Co. of New York City. Written mostly by English scholars, the first twelve volumes dealt with the history of the world from 1450 up to 1870. The final volume, numbered 12, was The Latest Age and appeared in 1910. There then followed two supplemental volumes.

The history was later followed by similar multi-volume works for the earlier ages, namely the Cambridge Ancient History and the Cambridge Medieval History.Leslie Bethell, The Cambridge history of Latin America: Latin America since 1930 (vol. 6), p. 11 As the first of such histories, it later came to be seen as establishing a tradition of collaborative scholarship.Roberto González Echevarría, Enrique Pupo-Walker, 'Introduction', in The Cambridge History of Latin American Literature vol. 2 (1996), p. xvii: "The Cambridge history of Latin American literature draws upon a long tradition of collaborative scholarship that began with the Cambridge modern history (1902–1912)..."

A second edition of the atlas (volume XIV) was published in 1924.William Robert Shepherd, Historical Atlas (1964), p. iv
