It is not easy to distinguish between cultural, economic and political causes of the War of Independence in Spanish America and separate them into three closed compartments. Then there are psychological obstacles. There is a feeling among many Latin Americanists that this topic is exhausted and further research will add nothing new. Others want a complete revision of the usual causes cited and demand more documentary study. They believe that the standard causes are based on too scanty research, mostly done in the last century from incomplete sources. Furthermore, there are the rising nationalists and indigenistas of our century, most of them poor historians, who insist that the role of the Indians and mestizos was much more important than historians have accepted. They consider past historians racially and economically prejudiced. Such a trend is especially strong in Mexico, Bolivia, and Cuba, the three countries that have faced a real social revolution. And, unfortunately, history often follows the flag.
