Answer:
Aging populations
Explanation:
The industrialized countries are facing a big demographic problem in the past few decades. The problem is the aging population. The living conditions in this countries are the best in the world, so they have high life expectancy, and while that is good, a problem occurs because the birthrates are very low. The birthrates are so low that they can not even simply sustain the same number of the population. This situation leads to fewer and fewer young people, and more and more elderly people, so the population pyramid is becoming wider at the top and narrower at the bottom.
The Spanish Civil War started in July 1936 with the military coup leaded by General Franco, which started a rebellion against the democratically elected Republican goverment. Since the establishment of a Republic and the abolition of the monarchy in 1931, mostly left-wing parties and progressisf leaders had won the elections.
The most conservative sectors of the army followed the fascist general Franco who, during the war, received the support of Hitler and Mussolini, specially, of their aviation military units. The democratic European states refused to help the Spanish Republic and only the URSS contributed by sending some armament.
The war ended in 1939 with the victory of the fascists and the establishment of a military dictatorship that would last until the death of Franco, the dictator, in 1975.
