Final answer:
President Zachary Taylor died in July 1850 from cholera morbus, also known as acute indigestion. His death led to Millard Fillmore becoming the President.
Step-by-step explanation:
In July 1850, President Zachary Taylor succumbed to cholera morbus, commonly referred to as acute indigestion.
While this ailment is non-lethal by contemporary medical standards, the limited advancements in 19th-century medical science rendered it difficult to treat effectively at that time.
The lack of advanced medical interventions contributed to Taylor's unfortunate demise.
Consequently, Vice President Millard Fillmore assumed the presidency following Taylor's death.
The historical episode underscores the stark contrast between medical capabilities in the 19th century and modern times, emphasizing the evolution of medical knowledge and technology over the years.
Taylor's passing not only marked a significant moment in American history but also highlighted the historical context in which medical understanding and treatment modalities were constrained, contributing to the chain of events that led to Fillmore assuming the role of President.
