History is a weapon. The powerful have their version of events, the people have another. And if we understand how the past was forged, we arm ourselves to change the future. This is a history of struggle, revolution and social change: of hominins, hunters and herders; of emperors and slaves; of patriarchs and women; of rich and poor; of dictators and revolutionaries. From the ancient empires of Persia and Rome to the Russian Revolution, the Vietnam War, and the 2008 Crash, this is a history of greed and violence, but also of solidarity and resistance. Many times in the past, a different society became an absolute necessity. Humans have always struggled to create a better life. This history proves that we, the many, have the power to change the world.
