On August 25, 1645, Edward Somerset, 2nd Marquess of Worcester, acting on behalf of King Charles, signed a treaty ("peace agreement") in Kilkenny with the Irish Catholic Confederates. He did not talk about this with the Irish Protestant community. Irish Protestants were strongly against this, and Charles was forced to undo the treaty almost immediately. He was afraid that almost all Irish Protestant would give support to the other side in the English Civil War.
