How and why did the Tsar rule with absolute power?

The Tsar ruled with absolute power in Russia primarily through the doctrine of autocracy, which asserted that the monarch was God's appointed ruler, holding ultimate authority over the state and its people. This power was maintained through a centralized government, a strong military, and extensive use of secret police to suppress dissent. The Tsar's control was reinforced by the support of the Russian Orthodox Church and the nobility, who benefited from the existing social hierarchy. Ultimately, this concentration of power aimed to maintain stability and control in a vast and diverse empire.
