At the beginning of Chapter Two of Animal Farm, Old Major dies in his sleep. This event galvanizes the animals into action, as we learn from the text:

Major’s speech had given to the more intelligent animals on the farm a completely new outlook on life.

While the animals have no idea when the rebellion against Man will occur, they are certain they must prepare for it. They begin to organize themselves; the pigs, "generally recognized as the cleverest," became the leaders. They take the text of Old Major's speech and turn it into a "complete system of thought" called Animalism. The pigs teach these principles to the other animals at secret meetings they hold in the barn on several nights of the week. They also sing the song "Beasts of England," which Old Major taught them before he died. 

It is now just a matter of time before the Rebellion takes place and the animals successfully overthrow Mr. Jones and take control of Animal Farm.
