What caused each county to have state funded public school?

State-funded public schools were established in each county primarily due to the push for universal education during the 19th century, driven by the belief that an educated citizenry is vital for democracy and economic development. Legislation, such as the establishment of compulsory education laws and funding through state taxes, provided the necessary financial support for public schooling. Additionally, the rise of the common school movement advocated for accessible education for all children, regardless of socioeconomic status. These factors collectively led to the establishment of state-funded public schools across counties.
