Germany felt threatened by Russia’s mobilization of troops.

Explanation: after the Sarajevo assassination and Austria-Hungary’s move against Serbia, Russia began mobilizing to support Serbia. Germany viewed Russian mobilization as an immediate military threat (and effectively an act of war), issued ultimatums, and when Russia did not stand down, Germany declared war on August 1, 1914.
