Bohemia-Moravia granted autonomy.
Under what regime? OTL, their diets had German majorities until 1871. Do we get a situation like in Belgium, where the Walloons ran the place though the Flemings outnumbered them?
The German Empire is declared, which absolutely terrifies Britain.
Why? The Germany of 1871 is not a naval power, so is far less of a worry than a strong France would be. It's only a problem if she gives Russia strong backing in the Balkans, an area in which few Prussians are interested.
