But there was a problem. The problem was that many Slavic people lived in Russia. And many Russians started protesting the invasion of Bosnia. How could they agree to the Austro-Hungarian empire getting control of Slavic people? The Russian empire was already weak. It had to abide by the wishes of the people. So despite the secret agreement, the Russian foreign minister started supporting Serbia.
It was 1909, the Austro-Hungarian empire turned towards Germany and asks them if they capture Serbia, and Russia comes to interfere, would Germany help the Austro-Hungarian empire? Germany agrees to help them as they were old friends. They’d definitely help. On the other hand, Russia asks France, Austro-Hungarian empire had first invaded Bosnia, and when Serbia objected to it, the Austro-Hungarian empire and Germany, had joined forces to attack Serbia.
Russia proposed that France should join its forces with Russia to fight against them. But France replies that it has nothing to do with Bosnia. regardless of what happened, they didn’t want to interfere in the matter. France’s refusal silenced Russia. And it had to accept the annexation of Bosnia.
