Anarchist societies did not truly succeed. Anarchy was used to exist outside of a government system. Anarchy was also a way to share property amongst every individual without capitalism. However, that never truly happened.
The anarchy that Americans had towards Great Britain wasn’t true anarchy. Instead, America built their own government with a president instead of implementing communal ideas. Capitalism also exploded in the past couple of centuries. Therefore, there’s no communal sharing of property.
The uprising against Julius Caesar was also not an example of true anarchy. Instead, it was an assassination attempt that resulted in the killing of assassins, a war between three large military forces, and another emperor. The assignation and act of rebellion failed to free Rome of an emperor-led country. Instead, it encouraged it even more.
Anarchy struggles to be possible today. For example, Freetown Christiania struggles to have law enforcement keep their beliefs and land. Other anarchist communities don’t even keep the characteristics of anarchy, like the Rojava community. Anarchy has not thrived over the centuries. Instead, it’s becoming nonexistent.
