Although Francisco Franco took power in Spain more than ten years after Benito Mussolini took power in Italy, their respective rises to power were based on similar factors. Economically speaking, both men rose to power because of economic downturns and strife.
In Italy, the end of WWI brought with it economic and political chaos. This led to things like huge numbers of strikes in factories. This chaos badly harmed the Italian economy. In Spain, the problem was the Great Depression, not WWI. But the same types of economic issues were present in Spain. Fascism and dictatorship are most appealing to those who are living in chaos and uncertainty. Both Spain and Italy suffered from this, helping cause the rise of fascist dictators.
