Roots and History

The origin of this idiom dates back to the 18th century, where it was commonly used in engineering and construction. In these fields, chains were often used to hold heavy objects or support weighty structures. If one link in the chain failed, the entire structure could collapse. The phrase gained popularity in business and politics as a metaphor for how the success of a system or organization depends on the individual parts' strength and competence.
