Final answer:
Russia's war difficulties were largely due to poor leadership, supply shortages, and internal unrest, which affected military morale and effectiveness and led to widespread political turmoil.
Step-by-step explanation:
Factors that contributed to Russia's war difficulties included poor leadership, supply shortages, and internal unrest. Mismanagement and incompetence characterized much of the military hierarchy, which led to massive casualties and prisoners of war. The Tsarist government struggled with the logistics of war, failing to sufficiently supply the military with arms and munitions.
Russia's efforts to industrialize were insufficient, with railroads unable to move troops and goods effectively, exacerbating food and equipment shortages. The home front suffered greatly, with long lines for food and riots in cities due to shortages. These supply issues greatly affected troop morale and consequently, military effectiveness. Political turmoil compounded these problems, as widespread dissatisfaction with the Tsar's leadership and economic troubles led to protests, strikes, and rebellions, eventually culminating in the Russian Revolution.
