Kollwitz wanted to show the horrors of living through a war to combat the pro-war sentiment that had begun to grow in Germany again. In 1924 she finished her three most famous posters: "Germany's Children Starving", "Bread", and "Never Again War". Working now in a smaller studio, in the mid-1930s she completed her last major cycle of lithographs, "Death", which consisted of eight stones: "Woman Welcoming Death", "Death with Girl in Lap", "Death Reaches for a Group of Children", "Death Struggles with a Woman", "Death on the Highway", "Death as a Friend", "Death in the Water", and "The Call of Death." When Richard Dehmel called for more soldiers to fight in World War I in 1918, Kollwitz wrote an impassioned letter to the newspaper he published his call in stating that there should be no more war, and that "seed corn must not be ground" in reference to young soldiers who were dying in the war. In 1942, she made a piece by the same name, this time in reaction to World War II. The work shows a mother, arms cast over three young children to protect them. In 1933, after the establishment of the National-Socialist regime, the Nazi Party authorities forced her to resign her place on the faculty of the "Akademie der Künste" following her support of the "Dringender Appell". Her work was removed from museums. Although she was banned from exhibiting, one of her "mother and child" pieces was used by the Nazis for propaganda.“They give themselves with jubilation; they give themselves like a bright, pure flame ascending straight to heaven.” In July 1936, she and her husband were visited by the Gestapo, who threatened her with arrest and deportation to a Nazi concentration camp; they resolved to commit suicide if such a prospect became inevitable. However, Kollwitz was by now a figure of international note, and no further action was taken. On her 70th birthday, she "received over 150 telegrams from leading personalities of the art world," as well as offers to house her in the United States, which she declined for fear of provoking reprisals against her family. She outlived her husband (who died from an illness in 1940) and her grandson Peter, who died in action in World War II two years later. She was evacuated from Berlin in 1943. Later that year, her house was bombed and many drawings, prints, and documents were lost.
