He descended from the royal dynasty of the western Georgian kingdom of Imereti, which had been conquered by the Russian Empire in 1810.
Like his elder brother, George, Michael Imeretinsky received his early education at the Lancing College in the United Kingdom and enlisted in the Royal Flying Corps as a sub-lieutenant in 1918.
[1] After his retirement from the military, Imeretinsky lived in the United Kingdom and France.
He devoted himself to agriculture, being—as his obituary put it—"a prominent member of the Soil Association and a well-known horticulturist in France.
"[2] In 1975, he died, aged 75, in Nice, being the last direct male descendant of the kings of Imereti.
