How did Nicholas address social unrest?

Nicholas II did not care about the unrest.

Explanation:

The Russian Revolution is the result of decades of bad rule by Russian autocratic kings. Decades of bad politics have brought the great country to the brink of social and societal ruin. Russia lags far behind other European countries in economic terms. In such conditions, dissatisfaction was growing among the people. The Russian tsar did not care much for the bad position of his people. He was only interested in his social status. For years, the people went on strike and tried to change their poor social status. Since these actions did not bear fruit, a revolution broke out in 1917, after which the tsar lost his position, and the Bolsheviks came to power with their socialist ideas.
