Consequently, rationing of bread, tea, sugar and meat was introduced in 1918. This was widely welcomed by the british public, as a voulentary rationing system had been introduced a year before, and people were eager to see their neighbours taking part as they were. Living standards plummeted, and the post-war economic state of Europe was at mid 19th century levels. During the war, 8 to 10 million soldiers were killed in battle, and 22 million were injured.
