Wales

Formal higher education in the arts and sciences in Wales, from the Middle Ages to the 18th century, was limited to the wealthy and the clergy. Following the Roman occupation and the conquest by the English, education in Wales was at a low point during the early modern period; in particular, formal education was only available in English while the majority of the population spoke only Welsh. The first modern grammar schools were established in Welsh towns such as Ruthin, Brecon, and Cowbridge. One of the first modern national education methods to use the native Welsh language was started by Griffith Jones in 1731. Jones became rector of Llanddowror in 1716 and remained there for the rest of his life. He organized and introduced a Welsh language-circulating school system, which was attractive and effective for Welsh speakers, while also teaching them English, which gave them access to broader educational sources. The circulating schools may have taught half the country's population to read. Literacy rates in Wales by the mid-18th century were one of the highest.
