Old Major holds a meeting in Manor farm for all the animals regarding a dream he got. This inspired Old major to wish for a rebellion. Manor Farm was owned by Mr. Jones, an irresponsible and alcoholic farm owner, that old Major wished to overthrow. Old Major died, so two pigs named Napoleon and Snowball gain control of the farm and establish laws that the animals have to follow.
The animals begin to follow a set of specific commandments of what they can and can't follow/do. The animals work to sustain the farm and gain food from it. Napoleon and Snowball being to disagree on certain choices being made on the farm, such as establishing a windmill on the farm. Napoleon kicks Snowball out of the farm with his guard dogs and officially makes the rules.
The commandments set from before are being slightly altered by the pigs and Squealer corrects the misconceptions being made about it from the animals on the farm. Being the leader on the farm, Napoleon enforces the laws and is looked upon as the supreme leader, although pigs serve a higher value than the other animals.
Incidents such as the destruction of the windmill, shortages of food, and sabotages of the farm worry the farm animals. Napoleon convinces the animals that Snowball is the one behind the chaos. Napoleons starts to kill a few of the farm animals who had relations with Snowball with his guard dogs.
The animals are working laboriously and seem to be in horrible conditions compared to the life they were living with Mr. Jones. The Animals are clearly not equal to the pigs who get more food and officially broken the original commandments.
The pigs being to display human traits such as walking on two legs and associating with other humans. The commandments have no longer been in use and is replaced with the phrase, " all animals are equal but some are more equal than others." The animals cannot see differences between the pigs and humans representing how alike they have become.
