Which animals were sent to spread the revolutionary ideas of Snowball and Napoleon to other farms?

The choice of pigeons as the animals sent to spread the revolutionary ideas of Snowball and Napoleon aligns with the symbolic role that pigeons play in literature and history. Pigeons are often associated with messages and communication due to their ability to fly long distances and return home, which makes them ideal messengers. In the context of "Animal Farm," the use of pigeons reflects a strategic approach to disseminating propaganda and fostering unity among different farms, emphasizing the importance of spreading their revolutionary ideals beyond their own farm.

This choice also highlights the theme of propaganda in the novel, as the pigeons are utilized to convey messages that reinforce the leadership and principles established by Snowball and Napoleon, demonstrating how effective communication is crucial for maintaining control and expanding influence in a revolutionary context.
