Particularly from 1638 to 1653, John Milton was deeply engaged in Ireland, although his relationship with Ireland is less well known than Edmund Spenser’s. The 1641 Ulster Rising in Ireland informs Milton’s political development, culminating in his service to Cromwell’s republican government. As the Introduction details, the 1641 Rising follows decades of strife in Ireland, following on the 1541 acceptance of Henry VIII as king of Ireland, Counter-Reformation changes in the Roman Catholic Church, and successive English plantation attempts at reforming Ireland, including the Ulster Plantation (which started the year after Milton was born).
