September 6 links journeys, reform, and political change across nearly five centuries. In 1522, the surviving members of Ferdinand Magellan’s expedition returned to Spain, completing the first circumnavigation of the globe—a landmark achieved by those who finished the voyage, not by Magellan himself. In 1860, Jane Addams was born; she would co-found Hull House and become a leading advocate for social reform and peace, receiving the Nobel Peace Prize in 1931. These events point to different kinds of journeys: one across oceans, another through the work of building institutions and pursuing social change.
The date also marks abrupt and deliberate shifts in political life. In 1901, President William McKinley was shot in Buffalo by anarchist Leon Czolgosz; in 1948, Princess Juliana became queen after her mother, Wilhelmina, abdicated. Taken together, the entries show how a single calendar date can hold both beginnings and turning points, from Addams’s birth to a change of monarch. Early September, as summer gives way toward autumn in much of the Northern Hemisphere, often feels like a season of transition; this list echoes that mood, while its wide span of years reminds us that history’s changes unfold at very different speeds.
