of the United Kingdom and King George I of Greece. Great solicitude was devoted to the education of Nicholas as tsesarevich, whereas Alexander received only the training of an ordinary Grand Duke of that period. This included acquaintance with French, English and German, and military drill. As Tsarevich Alexander became tsesarevich upon Nicholas's sudden death in 1865. He had been very close to his older brother, and he was devastated by Nicholas' death. When he became tsar, he reflected that “no one had such an impact on my life as my dear brother and friend Nixa [Nicholas]" and lamented that "a terrible responsibility fell on my shoulders" when Nicholas died.

The couple spent their wedding night at the Tsarevich's private dacha known as "My Property". Alexander and his father became estranged due to their different political views. In 1870, Alexander II supported Prussia in the Franco-Prussian War, which angered the younger Alexander. Influenced by his Danish wife Dagmar, Alexander criticized the "shortsighted government" for helping the "Prussian pigs". Alexander resented his father for having a long-standing relationship with Catherine Dolgorukov (with whom he had several illegitimate children) while his mother, the
