Orwell’s opposition to totalitarianism was rooted in his support for freeing workers from poverty and exploitation... and his earlier writings show how his convictions were formed and evolved.

Orwell’s opposition to totalitarianism was rooted in his support for freeing workers from poverty and exploitation

George Orwell, the author of two classic anti-totalitarian, pro-freedom novels from the 1940s, was a democratic socialist who opposed authoritarian leaders of the left and the right.

Archaeologists are unearthing the most powerful women who ever lived

Astonishing new archaeological finds and ancient DNA analysis leave no doubt that throughout prehistory women were rulers, warriors, hunters and shamans
