Ireland during the period 1536–1691 saw the first full conquest of the island by England and its colonisation with
Protestant settlers from Britain. This established two central themes in future Irish history – subordination of the country to London-based governments and
sectarian animosity between Catholics and Protestants. This period also saw the transformation of Irish society from a locally driven, intertribal,
clan-based
Gaelic structure to a centralised, monarchical, state-governed society, more like those found elsewhere in Europe. The period is bounded by the dates 1536, when
Henry VIII of England deposed the
FitzGerald dynasty as Lords Deputies of Ireland (the new
Kingdom of Ireland was declared by Henry VIII in 1541) and 1691, when the Irish Catholic
Jacobites surrendered at Limerick, thus confirming British Protestant dominance in Ireland. This is sometimes called the
early modern period.
