The novel leads us to believe over time that this must have been an on-going problem of Mr. Jones. The representation of Mr. Jones was Nicolas II, the ruling Romanov during Russia's last moments of rule from a monarchy.
During the Romanov family's last few rulers, alcohol came to dominate the family, and in Nicolas II's reign specifically encountered his wife dealing with mysticism. They became more concerned with marrying into European monarchies than they were with the needs of the Russian people. It began to grow worse and worse. This is represented by the animals need for a rebellion.
The animals of Manor Farm are disgruntled with the living conditions imposed by their human owner, Mr. Jones. Often drunk, Jones allows his animals to go hungry and without warmth in cold weather. Old Major, Jones' prize white boar, calls the animals together to unite them against their human master, who he claims takes without producing. If the animals revolt and rid themselves of the humans, they will become rich and contented. Humans are enemies of animals, Old Major tells them, and four-legged creatures deserve the right to be free just as their two-legged counterparts.
Three days after his speech, Old Major dies, and the other animals make preparations for a revolt. When the drunken Jones forgets to feed them, the animals break into the barn and help themselves to the feed. When Jones and his men arrive with whips, the animals drive them off the farm. "Animal Farm" is established with a set of commandments for the loyal creatures to follow.
