Laura Ingalls married farmer Almanzo Wilder in De Smet, Dakota Territory, beginning a lifelong partnership.
On February 25, 1885, eighteen-year-old Laura Ingalls married Almanzo James Wilder, a homesteader ten years her senior, in De Smet, Dakota Territory. The ceremony was simple and private, reflecting the modest means of frontier settlers at the time.
Their marriage would prove to be a defining partnership, lasting until Almanzo's death in 1949—over sixty years. The couple faced significant hardships together in their early years, including crop failures, a devastating diphtheria illness that partially paralyzed Almanzo, the death of their infant son, and a fire that destroyed their home. These struggles eventually led them to relocate to Mansfield, Missouri, where they established Rocky Ridge Farm.
This marriage is historically significant not only as a personal milestone but because it shaped the trajectory of Laura's later writing career. Almanzo's steady support, and the couple's shared experiences of agricultural life, directly inspired volumes of the Little House series, including Farmer Boy and These Happy Golden Years. Their daughter, Rose Wilder Lane, born the following year, would later play a controversial but important role in helping shape Laura's manuscripts into publishable form, becoming a notable writer in her own right.
