About this source

What it is

This is a published collection of telegrams exchanged between Tsar Nicholas II and Kaiser Wilhelm II of Germany, cousins who addressed each other informally as 'Nicky' and 'Willy'. The telegrams shown relate to July–August 1914, the tense weeks before war broke out, though the book collects correspondence from several years.

Why it matters

The telegrams reveal personal diplomacy between two monarchs trying, and failing, to prevent war between their empires. They were later published, with one introduction framing them as evidence against Wilhelm's regime, which shows how such documents can be used for political argument after the fact as well as for historical understanding.

Look closer

What tone do the two rulers use with each other, and how does that compare with the scale of the crisis they faced?
Why might this correspondence have been published, and by whom?
What does the failure of this personal diplomacy suggest about the limits of monarchs' power in 1914?
