Education in Wales was at a very low ebb in this period, with the only education available being in English while the majority of the population spoke only Welsh. In 1731 Griffith Jones started circulating schools in Carmarthenshire, held in one location for about three months before moving (or "circulating") to another location. The language of instruction in these schools was Welsh. By Griffith Jones' death, in 1761, it is estimated that up to 250,000 people had learnt to read in schools throughout Wales.
