"The persistence into the twentieth century of a specific institutional pattern inimical to growth in Mexico and Latin America is well illustrated by the fact that, just as in the nineteenth century, the pattern generated economic stagnation and political instability, civil wars and coups, as groups struggled for the benefits of power. Díaz finally lost power to revolutionary forces in 1910. The Mexican Revolution was followed by others in Bolivia in 1952, Cuba in 1959, and Nicaragua in 1979. Meanwhile, sustained civil wars raged in Colombia, El Salvador, Guatemala, and Peru. Expropriation or the threat of expropriation of assets continued apace, with mass agrarian reforms (or attempted reforms) in Bolivia, Brazil, Chile, Colombia, Guatemala, Peru, and Venezuela. Revolutions, expropriations, and political instability came along with military governments and various types of dictatorships. Though there was also a gradual drift toward greater political rights, it was only in the 1990s that most Latin American countries became democracies, and even then they remain mired in instability."
