The document outlines four main problems faced by Prussia between 1850-1950: 1) Physical blockade from world markets and resources by the United Kingdom, supported by the USA. 2) Threat to royal and aristocratic rule from industrialization, modernization, urbanization, and parliamentarianism, with socialist assassination attempts on the Kaiser in 1878. 3) Bourgeois resistance to modern materialistic changes in cultural values. 4) Rapidly evolving global balance of power versus Russia, UK, USA, France, and Japan in the "grab for world power" from 1914-1945.
