This work investigates the critical socio-economic and political shifts that transitioned Wales from an impoverished, agrarian society into a nation poised for industrialization between 1642 and 1780. Geraint H. Jenkins, a distinguished historian of Wales, utilizes a vast array of primary and secondary sources to construct a comprehensive narrative of this formative period. He argues that demographic expansion, agricultural innovation, and the emergence of early heavy industry collectively established the structural foundations of the modern Welsh state.

Historians and scholars of Welsh history recognize this volume as a definitive account of the early modern period. Readers frequently note the meticulous research and the clarity with which Jenkins synthesizes complex economic data into a coherent historical narrative.
