Answer
1916 marked the pinnacle of Russian influence during World War I. By this time, Russia had successfully repelled German advances and launched its own offensive, known as the Brusilov Offensive. This offensive, named after General Alexei Brusilov, achieved significant territorial gains and inflicted heavy casualties on the Austro-Hungarian forces. Russia's military successes in 1916 bolstered its position as a major power and contributed to the overall Allied war effort.
