Henry had broken away from the Holy See and declared himself the head of the Church in England, and subsequently refused to recognise the Roman Catholic Church's vestigial sovereignty over Ireland. For this reason, and also to address England's waning power in Ireland, Henry proclaimed the Kingdom of Ireland in 1542, with himself as its monarch. The following year, the Counties of Meath and Westmeath Act was passed by the Parliament of Ireland and Meath was officially divided in two. The act was intended to allow a more effective administration in both counties, particularly in Westmeath, which England had lost control of. A new shire town at Mullingar was established along with four new baronies, while Trim retained its status as the shire town of Meath.
