political disorder  

Explanation:

The term "black forest" used by Dante in his work means political disorder. Dante parallels black forests and politics; This is because, the black forests are difficult environments, dark and that causes confusion to man. The same happens when the political disorder happens, the man gets dark, difficult and confused. A black forest can cause humanity much harm, as can the political disorder that can end a society through the problems it causes.
