Revolutions are major and often rapid changes in government or society. They can involve large groups of people and sometimes include protests or conflict. These events have taken place in many parts of the world.

Some revolutions focus on political change, such as replacing a monarchy with a new system of government. Others, like the Industrial Revolution, involve changes in technology and production. These events can lead to new laws, leaders, and social systems.

Revolutions are studied using documents, timelines, and historical records. They help show moments when societies changed direction.
