The purpose of this article is to discuss and make available two documents written in Cavan in 1633, which detail the complaints made by the Protestant laity and clergy against the imposition of taxation and their fears as to the relaxation of anti-recusancy laws. Whereas in 1629 a petition had been prepared by the people in Cavan in general, and signed both by Catholics and Protestants, the petition discussed and transcribed here (Appendix I) was explicitly one from the Protestant planter community in Cavan. The second document (Appendix II) is a letter by the Church of Ireland bishop, William Bedell. It describes in detail the circumstances which led to the writing of the 1633 petition. Together, both documents afford us a rare insight into the motivations and interests of the Protestant planter community in south Ulster at this time of stress.
