What are the reasons for the main results of the February bourgeois revolution of 1917?

The main reasons for the February Revolution in Russia were the First World War, which took on a protracted and unsuccessful character for us, and also the inability of the monarchical regime to lead the country to victory and to resolve internal problems. The protests in the capital, which began with demands for bread, quickly escalated into radical political demands.
The main consequences were the abdication of Nicholas II from the throne and the fall of the monarchy, the coming to power of the Provisional Government, unable to realize the aspirations of the people, the Bolshevik coup, the Civil War and the communist dictatorship.
