Creighton was heavily influenced by
Harold Innis and took an economic approach to
Canadian history. His significant contribution to the field was the development of the Laurentian thesis, which defined the basis of Canadian history through geography and the nation's dependence on its major centres. Creighton's first works were studies in the Rebellion of 1837–38 in
Lower Canada, which Creighton believed to be the product of a clash between the economic traditionalism of
French Canada and the relentless drive of the
Anglo business elite of
Montreal. In turn, this led Creighton to the study of that elite, and hence into the study of the
St. Lawrence in Canadian history. In
The Commercial Empire of the St. Lawrence, Creighton argued that the economic potential of the St. Lawrence system inspired successive generations of adventurers, explorers and businessmen to try to link the vast
natural resources of the interior of North America with Europe. Despite heroic efforts, the dream of the St. Lawrence failed to come to life as too many impenetrable portions of the river meant it could not live up to its potential, and the development of a railroad system in the US proved to be more economical. Creighton was well known for arguing that the "natural" basis of trade in Canada ran east–west rather than north–south. In Creighton's view, the failure of commercial elites to properly develop the St. Lawrence is what led to
Confederation. Creighton argued that since impassable waterfalls and rapids prevented an economic empire from being built, Canadian elites embraced a political empire, namely Confederation as a consolation prize. The theme of Confederation as a poor substitute for an economic empire was underlined in
The Road To Confederation and Creighton's biography of Macdonald. Creighton's two most important works are
The Commercial Empire of the St. Lawrence (1937) and his two-volume biography of
Sir John A. Macdonald, entitled
Young Politician and
Old Chieftain. Both volumes won the
Governor General's Award for best non-fiction book in 1952 and 1955, were major best-sellers, and were credited with creating a major reassessment of Macdonald's role in Canadian history. In Creighton's view, Macdonald sought Confederation as a way of bringing to life the political St. Lawrence empire. Creighton saw history as a literary art and rejected calls for history to be seen as
social science. Creighton was famous for spending as much time crafting his prose as he did in research, and Creighton often claimed that the best historical work should read like a well written novel. Creighton disliked what he called "fat funereal volumes" of unreadable biographies, and argued that well-written books should be the historian's objective. Creighton's major influences were
R. G. Collingwood,
James Anthony Froude,
G. M. Trevelyan,
Edward Gibbon, and
A. J. P. Taylor. Creighton's vision of Canadian history was ultimately a deeply pessimistic and tragic one as he felt Canada had the potential to be the world's greatest country if only Canadians would follow the vision of the Fathers of Confederation, especially Macdonald's. In his view, most Canadian leaders had chosen to neglect that vision and had instead allowed Canada's potential to be squandered. The only leaders who merited the description of statesmen, in his view, were Macdonald and
Sir Robert Borden. According to Creighton, Macdonald's time in office was Canada's Golden Age and without the exception of Borden every leader who came after Macdonald had allowed Canada to deteriorate. Thus for Creighton, Canadian history after 1891 was for the most part the story of missed opportunities, thwarted ambition, and hopes scattered as the dream that was Canada was slowly allowed to unravel. Though Creighton normally tried to maintain a formal and cold pose, he was well known for his outspoken and passionate nature. His eruptions of rage led his publisher John Gray to call him "the terrible-tempered Mr. Bang". Creighton often engaged in feuds with historians whose interpretations he disliked, but he was known to be kind-hearted and munificent towards his students, albeit severe with those who engaged in work that he thought was wrong-headed. He made no effort at objectivity and was openly subjective and partisan in regards to his likes and dislikes. Creighton was fond of contrasting Canada's participation in the First World War and the Second World War. In Creighton's view, Robert Borden was a tough and able leader who, despite initial mistakes and missteps, was able to fully mobilize Canada and ensure that Canada contributed disproportionately to the Allied victory in 1918. Borden took the necessary steps to win the war despite the unpopularity of many of his measures. Creighton saw the rest of Canadian history as one long slide, which he largely blamed on the Liberal Party. In contrast, Creighton saw
William Lyon Mackenzie King as a weak and indecisive figure who was more concerned with safeguarding the electoral fortunes of the Liberals than winning the war, and who kept Canadian troops out of combat as long as possible to avoid difficult decisions on
conscription. In Creighton's opinion, thanks to Mackenzie King, Canada did not play as large a share as possible in the Allied victory. Creighton was regarded by many as the foremost historian of his day, and his influence is still strongly felt. His books received wide public attention. Many of Canadian historians studied under Creighton, including
Ramsay Cook,
H. V. Nelles, and
Michael Bliss. Creighton's view of Canadian history is still often studied. He helped initiate the
Canadian Centenary Series, a nineteen-volume history of Canada, and served as its advisory editor. His book,
The Forked Road: Canada, 1939–1957, was part of the
Centenary Series. == Creighton as a nationalist ==
