of Persia with an offer of alliance, so as to check the advances of
Russia on the shores of the Caspian.[15]

On the other hand, he used every effort to allure Prussia, by secretly
offering her Hanover, and that too as early as the close of July.[16]
For a brief space, also, he took some pains to conciliate Austria.
This indeed was necessary: for the Court of Vienna had already
(November 6th, 1804) framed a secret agreement with Russia to make war
on Napoleon if he committed any new aggression in Italy or menaced any
part of the Turkish Empire.[17] Yet this act was really defensive.
Francis desired only to protect himself against Napoleon's ambition,
and, had he been treated with consideration, would doubtless have
clung to peace.

For a time Napoleon humoured that Court, even as regards the changes
now mooted in Italy. On January 1st, 1805, he wrote to Francis,
stating that he was about to proclaim Joseph Bonaparte King of Italy,
if the latter would renounce his claim to the crown of France, and so
keep the governments of France and Italy separate, as the Treaty of
Lunéville required; that this action would enfeeble his (Napoleon's)
power, but would carry its own recompense if it proved agreeable to
the Emperor Francis.

But it soon appeared that Joseph was by no means inclined to accept
the crown of Lombardy if it entailed the sacrifice of all hope of
succeeding to the French Empire. He had already demurred to _le vilain

the offer. Napoleon then proposed to Louis that he should hold that
crown in trust for his son; but the suggestion at once rekindled the
flames of jealousy which ever haunted Louis; and, after a violent
