There are few ideas more sacred than the physical, emotional, and spiritual connections individuals have had with nature. The love of these beautiful landscapes has inspired countless generations to protect and preserve these lands and to make sure that the wild, untamed beauty will continue to awe future generations who have yet to come across their magnificence. On March 1, 1872, Yellowstone National Park was federally recognized as the country’s first protected area, 44 years before the National Park Service was founded in 1916. And with this first step, the conservation, culture, history, and preservation of parks and protected areas began. Not only do these parks and protected areas ensure the vitality of natural resources, but of historical and cultural resources as well. Constructing and defining the National Park Service as the revered organization that it is today was no easy task. While some individuals have used their talents to create and preserve the physical landscape—physically building the parks and developing policies and laws—others have used their literary and artistic skills to showcase their beauty and history. No one person is the guardian or champion of these protected areas—with collaboration, vision, and connection to the land, we are part of the parks equally as the parks are part of ourselves.

On June 28, 1919, Germany and the Allied Powers signed the Treaty of Versailles in the Hall of Mirrors at the famous Palace of Versailles, officially ending World War I. World War I, or the Great War, lasted from 1914 to 1918, and claimed the lives of nearly ten million soldiers and approximately thirteen million civilians. Germany and its allies in the Central Powers had lost the war, so representatives of the victorious Allied Powers including the United States, France, and Britain negotiated the terms of the treaty. President Woodrow Wilson and his allies wanted the treaty to provide a lasting peace following Wilson’s Fourteen Points speech delivered on January 8, 1918. European powers sought peace but also wanted to punish Germany, who they blamed for causing the war. Germans also expected that the Fourteen Points would be the basis for the peace talks when they signed the armistice in November 1918. When the Allied Powers met in Paris to discuss the world after the war, however, a much more punitive plan emerged.

In 1853, the City of New York set aside hundreds of acres of swampland in the middle of Manhattan, with the idea that this uninhabitable space could serve a practical, public purpose. Today, we know that area as Central Park, one of the most widely visited and celebrated public spaces in the country. The then-unknown park designer who won the bid to design Central Park, Frederick Law Olmsted, would go on to inspire and revolutionize urban park design in the United States. The work of Olmsted and other early parks pioneers, building on older concepts like town squares, would spur the growth of urban parks large and small nationwide. Benefiting from new innovations in design, these parks serve as community centers and defining features of cities and towns across the country. Urban parks have continually adapted to meet the needs of the publics they serve, evolving, for example, from places to simply enjoy nature into recreation sites that offer activities and equipment. More than just sites for leisure, they also play a broader role in supporting community engagement by providing places for civic participation, enhancing quality of life and property values, and offering safe, healthy, and convenient recreation options. This exhibition was created as part of the DPLA’s Public Library Partnerships Project by collaborators from the Minnesota Digital Library. Exhibition Coordinator: Carla Urban.

In June 1941, German Chancellor Adolf Hitler violated a non-aggression pact with Josef Stalin and launched a massive invasion of the Soviet Union. This offensive, named “Operation Barbarossa,” was motivated by a desire to crush one of Europe’s last holdouts against Nazi domination as well as Hitler’s disdain for communism and the Slavic people. Additionally, Hitler sought to commandeer the Soviet Union’s natural resources, including natural oil and gas and vast agricultural areas of Ukraine that could serve as the Nazi “breadbasket.”
