History of education in Wales (1701–1870)
Between 1701 and the 1870 Elementary Education Act, access to formal education expanded in Wales, though remained short of universal. During the 18th century, several philanthropic efforts were made to provide education to poorer children and sometimes adults; these included schools established by the Society for Promoting Christian Knowledge (SPCK), circulating schools, Sunday schools and endowed elementary schools.
