who followed the policy of blood and iron
Blood and Iron (speech) In September 1862, when the Prussian House of Representatives was refusing to approve an increase in military spending desired by King Wilhelm I, the monarch appointed Bismarck Minister President and Foreign Minister. A few days later, Bismarck appeared before the House's Budget Committee and stressed the need for military preparedness to solve the German Question. He concluded his speech with the following statement:[1] "The position of Prussia in Germany will not be determined by its liberalism but by its power [...] Prussia must concentrate its strength and hold it for the favorable moment, which has already come and gone several times. Since the treaties of Vienna, our frontiers have been ill-designed for a healthy body politic. Not through speeches and majority decisions will the great questions of the day be decided—that was the great mistake of 1848 and 1849—but by iron and blood (Eisen und Blut)." This phrase, relying on a patriotic poem written by Max von Schenkendorf during the Napoleonic Wars, was popularized as the more euphonious Blut und Eisen ("Blood and Iron"), and became symbolic of Bismarckian Machtpolitik ("Power politics").
Red blood cell The blood's red color is due to the spectral properties of the hemic iron ions in hemoglobin. Each human red blood cell contains approximately 270 million[citation needed] of these hemoglobin molecules. Each hemoglobin molecule carries four heme groups; hemoglobin constitutes about a third of the total cell volume. Hemoglobin is responsible for the transport of more than 98% of the oxygen in the body (the remaining oxygen is carried dissolved in the blood plasma). The red blood cells of an average adult human male store collectively about 2.5 grams of iron, representing about 65% of the total iron contained in the body.[21][22]
