Russian Grand Duke
Dmitry was very religious and he assumed responsibility for the church of the Apparition of the Virgin near Strelna, which was the regimental church of the Horse Grenadiers. He commissioned both an enlargement and a renovation program, which he paid for himself.
The grand duke's main residence was the Palace of Strelna, where he lived a quiet life and was his main residence until the revolution. He lived in a suite of rooms of the ground floor on the west wing that had previously been occupied by his father. He had the palace electrified, telephones were installed and modern plumbing provided for the bathroom and the kitchen.
Dmitry Konstantinovich was fair, with blond hair and blue eyes, and wore a small cavalry mustache. He was tall and lean with long legs and a long neck that increased his extraordinary height. In a family known for the height of its male members, Dmitry was among the tallest. Grand Duchess Militsa considered him "the nicest and best among the grand dukes". He was proper, dignified and very refined in his manners.
Alexander Mosolov, head of Nicholas II's Court Chancellery, described him as "full of good sense", remarking that Dmitry Konstantinovich "was the one among all the grand dukes who was most deeply imbued with the sense of his duty as a Prince and a cousin of the Emperor".
One day, the grand duke dispatched a hefty portion of his annual civil list income to support a struggling church. When Mosolov learnt of this he warned, " If you make gifts everywhere on this scale, your revenues will not last." But Dmitry Konstantinovich replied that the stipend was "not intended to enable us to live as sybarites; this money is put into our hands in order that we may augment the prestige of the Imperial family".
The grand duke was a lifelong bachelor, never involved in scandals. In his memoirs, his cousin Grand Duke Alexander Mikhailovich recalled that he was "a confirmed and enthusiastic woman-hater", then a term used for misogynists but also homosexuals. That Dimitry had close affectionate relationships with the female members of his family suggests the latter. He was adored by his family and especially by his young nieces and nephews, with whom he would happily play and ride for hours. He was particularly close to the children of his brother Konstantin. His nephew Prince Gabriel Konstantinovich remembered him, as a "wonderful, kind person" who was almost a second father and wherever they saw him, they ran across the room, jumping up to hug him and wrap their arms around his neck. Dmitry Konstantinovich also loved to tease the children and play practical jokes on them.
Under Nicholas II, the grand duke received further promotions. On 26 May 1896, he was raised to the rank of Major-General, and three months later, he was named General à la suite in the Imperial Entourage. On 19 December 1904, Dmitry Konstantinovich was promoted to Lieutenant General and appointed Adjutant General to Nicholas II. Nicholas II also appointed the grand duke general director of the Imperial Stud in 1896. Despite his love of the military, it was this later post that struck the deepest chord in Dmitry Konstantinovich. On learning of his appointment, the grand duke – whom one courtier termed "timid beyond imagination" declared, " I should have eagerly accepted the appointment if it only meant looking after horse [...] I am afraid I shall never get on properly with officials."
Dmitry Konstantinovich was entranced with his new position, one of which demanded that he traveled across Russia and Europe, selecting the finest horses. Acting on his advice, the Imperial Stud purchased Galtee More, who had won the Derby in Great Britain, for an astronomical 200,000 rubles; as soon as he arrived in Russia, the thoroughbred was put to stud at Tsarskoye Selo. Dmitry Konstantinovich held the post until 1905, when he was replaced with Major-General Alexei Zdnovich. On 10 January 1904, Dmitry Konstantinovich relinquished command of the Horse Guard grenadiers Regiment. Although he would have been happy to remain in his post, his eyesight was failing rapidly, in detriment to his military career. Reluctantly he recognized that by remaining he was depriving another, more capable man of advancement. On leaving active service, the grand duke generously gave his dacha at Krasnoye Selo to the Horse Guards Regiment, to be used as an officer's club.
