Simon Sebag Montefiore said this quote

Very few politicians, who have chosen a political career, can fulfill the aspirations and survive the strains of an elevated office that in a monarchy was filled so randomly. Each tsar had to be simultaneously dictator and supreme general, high priest and Little Father. They required all the qualities listed by the sociologist Max Weber: the personal gift of grace, the virtue of legality, and the authority of the eternal yesterday.
