I think the answer you're looking for is communism. Fascism was however a result of many fears, some of them were the fear of certain minorities taking over the main part of economies (in Germany people believed that Jews were too powerful), and the fear of poverty, as people were thinking that only a strong government can provide for its people.
But in many places communism was used as a direct demagogic threat to gain support.
The Great Stink was an event in Central London in July and August 1858 during which the hot weather exacerbated the smell of untreated human waste and industrial effluent that was present on the banks of the River Thames.
