Context: Upon this battle depends the survival of Christian civilisation. Upon it depends our own British life and the long continuity of our institutions and our Empire. The whole fury and might of the enemy must very soon be turned on us now. Hitler knows that he will have to break us in this island or lose the war. If we can stand up to him, all Europe may be free and the life of the world may move forward into broad, sunlit uplands. But if we fail, then the whole world, including the United States, including all that we have known and cared for, will sink into the abyss of a new Dark Age, made more sinister, and perhaps more protracted, by the lights of perverted science. Let us therefore brace ourselves to our duties, and so bear ourselves that, if the British Empire and its Commonwealth last for a thousand years, men will still say, 'This was their finest hour.

1900s
Context: When I was in South Africa nothing was more inspiring, nothing more encouraging, to a Briton to find how the men who had either themselves come from its shore or were the descendants of those who had still retained the old traditions, still remembered that their forefathers were buried in its churchyards, that they spoke a common language, that they were under a common flag, still in their hearts desired to be remembered above all as British subjects, equally entitled with us to a part in the great Empire which they, as well as us, have contributed to make... I did not hesitate, however, to preach to them that it was not enough to shout for Empire... but that they and we alike must be content to make a common sacrifice... in order to secure the common good. To my appeal they rose. And I cannot believe that here in this country, in the mother country, their enthusiasm will not find an echo. They felt, as I felt, and as you feel, that all history is the history of States once powerful and now decaying. Is Britain to be numbered among the decaying States? Has all the glory of the past to be forgotten? Have we to prove ourselves unregenerate sons of the forefathers who left us so glorious an inheritance? Are we to be a decaying State? Are the efforts of all our sons to be frittered away? Are their sacrifices to be vain? Or are we to take up a new youth as members of a great Empire which will continue for generation after generation, the strength, the power, and the glory of the British race?
