 He saw himself as a soldier—a junior officer totally consumed by spit and polish.
 A handsome man, he was highly nervous and aggressive.
 Trained as an engineer, he was a stickler for minute detail.

 His reign had an ideology called "Official Nationality" that was proclaimed officially in 1833.
 It was a reactionary policy based on orthodoxy in religion, autocracy in government, and Russian nationalism.
 He was the younger brother of his predecessor, Alexander I.
 Nicholas inherited his brother's throne despite the failed Decembrist revolt against him and went on to become the most reactionary of all Russian leaders.
 His aggressive foreign policy involved many expensive wars, having a disastrous effect on the empire's finances.
