This book will have two primary aims of analysis: the migration of Flemings and their settlement. The first will be to identify systems and build models of migratory movements within a long-term perspective, i.e. understanding migration paths and causes, networks, strategies and migrants’ personalities. The second will focus on what is commonly known as ‘integration’, that is, the immigrants’ settlement, acculturation and acquisition of their social, economic and political position in the host country. In addition to a detailed treatment of these two aims, the book attempts to evaluate the economic impact of the immigrant community on a specific industry. I will argue that the success of the immigrants was not solely reflected in the rise of their average earnings, but also in the fact that their skills and human capital acquired prior to emigration contributed to the development of the English textile industry in the fourteenth century.
