What predetermined the split of society in Spain after the revolution at the beginning of 1930

In Spain, in the first half of the 20th century, there was a split in society. A historic choice arose between the people of one state regarding ideology and political structure. The people were divided into two camps. Some pursued the ideas of the socialists and belonged to the left parties. The second part went over to the side of the fascist parties, the right and the conservatives. In the 1930s, the revolution began in Spain due to the discrepancy between the interests of the citizens of one state. A movement began against the republican form of government.
