The Act for the Settlement of Ireland 1652 was passed by the Long Parliament after the Cromwellian conquest of Ireland, itself in response to the Irish Rebellion of 1641.
Ten named leaders of the revolt, together with anyone2 who had participated in its early stages and who had killed an Englishman other than in battle, lost their lives and estates.
Remaining leaders of the Irish army lost two-thirds of their estates. To have been merely a bystander was itself a crime and anyone who who had resided in Ireland any time from October 1, 1649, to March 1, 1650 and had not "manifested their constant good affection to the interest of the Commonwealth of England" lost one-third of their land. The Commissioners in Ireland had power to give them, in lieu thereof, other (poorer) lands in Connacht or Clare in proportion of value and were authorised "to transplant such persons from the respective places of their usual habitation or residence, into such other places within that nation, as shall be judged most consistent with public safety". This they interpreted liberally and ordered all Irish land owners to leave for those lands before 1 May, 1654 or be executed. (Hence the expression, "To Hell or to Connaught").
A further Act in 1667 (after the Restoration) aimed to reduce its effect on Protestant and "innocent Catholics".
James Butler Earl of Ormond, James Touchet Earl of Castlehaven, Ulick Bourke Earl of Clanricarde, Christopher Plunket Earl of Fingal, James Dillon Earl of Roscommon, Richard Nugent Earl of Westmeath, Morrogh O'Brien Baron of Inchiquin, Donogh MacCarthy Viscount Muskerry, Theobald Taaffe Viscount Taaffe of Corren, Richard Butler Viscount Mountgarret.
Note 2: "all and every person and persons, who at any time before the tenth day of November, 1642 (being the time of the sitting of the first General Assembly at Kilkenny in Ireland), have contrived, advised, counselled, promoted, or acted, the rebellion, murders, or massacres done or committed in Ireland, which began in the year 1641; or have at any time before the said tenth day of November, 1642, by bearing arms, or contributing men, arms, horse, plate, money, victual, or other furniture or hablements of war (other than such which they shall make to appear to have been taken from them by mere force and violence), aided, assisted, promoted, acted, prosecuted, or abetted the said rebellion, murders, or massacres";

"and every person and persons (both principals and accessories) who since the first of October, 1641, have or shall kill, slay, or otherwise destroy any person or persons in Ireland, which at the time of their being so killed, slain, or destroyed, were not publicly entertained and maintained in arms as officers or private soldiers, for and on behalf of the English against the Irish; and all and every person and persons (both principals and accessories) who since the said first day of October, 1641, have killed, slain, or otherwise destroyed any person or persons entertained and maintained as officers or private soldiers, for and on the behalf of the English against the Irish (the said persons so killing, slaying, or otherwise destroying, not being then publicly entertained and maintained in arms as officer or private soldier under the command and pay of the Irish nation against the English)."
