How was "Mary Ingalls'" cause of death incorporated into the series 'Little House on the Prairie'? The series is set in 19th-century America and shows a family's everyday farm life, which is often fraught with difficulties.

The true story behind 'Little House on the Prairie' is based on the diary entries of the family member Laura Ingalls Wilder. In the series, however, some incidents have been changed. However, the fate of "Mary Ingalls" - in the series and in real life - was not easy in both cases.

At the age of only 14, the real Mary went blind. As it turned out later, this was probably a consequence of previous meningitis. In the series, "Mary" went blind a little later - scarlet fever was also named as the cause.

Neither was "Mary Ingalls'" cause of death. But she had to live without her sight ever since, which was not to return until her death. The "real" Mary Ingalls eventually lived with her parents until she passed away.
