History
After the United States entry into WWII, Britain changed its security classifications to match American classifications. Prior to the U.S.'s coming into the war, the classifications included the top classification: "Most Confidential". Documents were then shared with the U.S., when they entered the war. However, these British classifications were not understood in the U.S., and classified information appeared in the U.S. press. This spearheaded the uniformity in classification between the UK and the U.S.

Famous quotes containing the word history:
“A man acquainted with history may, in some respect, be said to have lived from the beginning of the world, and to have been making continual additions to his stock of knowledge in every century.”
—David Hume (1711–1776)
“Yet poetry, though the last and finest result, is a natural fruit. As naturally as the oak bears an acorn, and the vine a gourd, man bears a poem, either spoken or done. It is the chief and most memorable success, for history is but a prose narrative of poetic deeds.”
—Henry David Thoreau (1817–1862)
“It may be well to remember that the highest level of moral aspiration recorded in history was reached by a few ancient Jews—Micah, Isaiah, and the rest—who took no count whatever of what might not happen to them after death. It is not obvious to me why the same point should not by and by be reached by the Gentiles.”
—Thomas Henry Huxley (1825–95)
