What was the age of majority in Pennsylvania prior to 1978?

Prior to 1978, the age of majority in Pennsylvania was legally established as 21 years old. This age signified the point at which an individual was recognized as an adult, capable of making legal decisions independently, including entering into contracts, voting, and other adult responsibilities. The establishment of 21 as the age of majority aligns with common historical norms in many states, which viewed this age as a threshold for adulthood. In changing the age of majority in 1978 to 18, Pennsylvania aligned more closely with the evolving social perceptions of adulthood and maturity among younger individuals.
