Final answer:
The Industrial Revolution was a major factor that led to reform in the late 1800s, resulting in changes to improve working conditions, public health, and social equality.
Step-by-step explanation:
One factor that led to reform in the late 1800s was the Industrial Revolution. This period brought about significant changes in society, such as the rise of urbanization and the growth of the industrial economy.
These changes led to poor working and living conditions for many individuals, especially the working class. The need for reform became apparent as people began to advocate for better working conditions, public health improvements, and social equality.
For example, laws were enacted to improve public health and living conditions, free education for elementary children was legislated, and government jobs were granted based on qualifications rather than social status or wealth.
