What mistake did the provisional Russian government make in 1917?

The provisional Russian government made the critical mistake of continuing to participate in World War I, which led to widespread dissatisfaction among the populace due to the ongoing casualties and economic strain. Additionally, it failed to address key social and economic issues, such as land reform and workers' rights, which fueled discontent. This lack of decisive action and inability to gain popular support ultimately weakened its legitimacy and paved the way for the Bolshevik Revolution later that year.
