Multiple local centres of power were reduced as the growing institutions of central government consolidated jurisdiction at the expense of provincial noble authority. The ways in which this long-term process of state-building in Ireland occurred were complex but a central role was played by print. The importance of print to government was made particularly clear in the 1640s. In the initial session of the parliament of 1640 the press was used by Lord Deputy Wentworth as a way of demonstrating control. As an institution, the established Church of Ireland also used print in the straightforward task of ensuring increasing administrative uniformity. From the institutional point of view, print made possible the extension of the central government's idea of a 'commonwealth' into the provincial world with very considerable social consequences.
