Russia lost the 1853-56 Crimean War. NATO member alert, code green—Russia lost to Britain, France, and Turkey.
In 1861 Tsar Alexander II freed 50 million serfs. If “freed” is the word that’s wanted. The serfs had no place to go except the land they were already farming, and if they wanted any of that, they had to buy it with the nothing they made as serfs. Later, as mentioned twice already, Alexander got blown to bits.
Russia lost the Jews. Being robbed, beaten, and killed in pogroms was not a sufficient incentive to stay. More than a million Jews emigrated, taking what common sense the country had with them.
Russia lost the 1904-05 Russo-Japanese War in the best Russian loser fashion at the naval battle of Tsushima.
Japanese Admiral Togo Heihachiro “crossed the T” of the Russian fleet, a rare execution of a tactic where you get your ships in a horizontal line so that your guns can be aimed at the enemy, whose ships are in a vertical line so that their guns can’t be aimed at you.
