In Animal Farm by George Orwell, what did the pigs call the government they formed using Old Major's ideas?

In Chapter Two, the pigs form a government in anticipation of the Rebellion against Mr Jones. This government is called Animalism and is described as a "complete system of thought." It is inspired by Old Major's speech in Chapter One in which he outlined the evil acts perpetrated by mankind against animals, like slaughter for profit. 

To spread the message of Animalism, the pigs conduct secret meetings at night to teach the principles of this system to the other animals. Initially, the other animals demonstrate "stupidity" and "apathy" towards Animalism but, over time, the pigs successfully convince them of its merits and of the wider need to overthrow Mr Jones and run the farm for themselves.

In the aftermath of the Rebellion, the pigs condense Animalism into Seven Commandments which form the foundation of their new society. These Commandments are written on the wall of the barn and become a symbol of hope for the future.
