Alexander was a member of the Meller-Zakomelsky family, being the great grandson of Ivan Ivanovich Möller-Sakomelsky.
His father was Nikolay Ivanovich Meller-Zakomelsky (ru) (1813—1887) — General-Adjutant, General of the Infantry.
To put down the protests, Meller-Zakomelsky gave orders to the soldiers to fire on the crowd: 70 people were killed, and 200 injured.
In the wake of the massacre, Meller-Zakomelsky took pride in the way his troops handled the situation, writing to the Tsar suggesting that there would be no more further trouble if more local authorities were willing to act as he had.
