The factors which lead to the rise of feudalism was the fact that people couldn't protect themselves and needed land where they could be safe considering the fact that a single peasant didn't have enough capabilities to defend himself. This lead to the fact that these peasants had to give food and goods to their lord with his army.

The 1920's saw a period of rapid industrialisation, which made the decade to be correctly called the Roaring twenties. However, it is only the industrialists who benefited from the boom, with the majority of the working population conditions remaining poor. This was a fragile situation that led to the great depression as few money was circulating in the larger population. This has led to some conspiracy theorists attributing the blame of the great depression to the industrialists and bankers.
