The Conciliatory Resolution was a resolution passed by the British Parliament in an attempt to reach a peaceful settlement with the Thirteen Colonies immediately prior to the outbreak of the American Revolutionary War.
In January 1775, Parliament considered petitions from the colonies in relation to the Coercive Acts, including a petition to the king from the First Continental Congress, and discussed ways to resolve the crisis with the Thirteen Colonies. A proposal by William Pitt to recognize colonial self-government was rejected by the House of Lords. Pitt then moved for the withdrawal of troops from Boston, but that motion was defeated. In February, Pitt presented a plan of conciliation based upon mutual concessions, but this was also rejected. On February 2, despite fierce opposition from some members of Parliament, New England was declared to be in rebellion. Lord North took the unexpected (for him, that is) role of conciliator for the drafting of a conciliatory resolution which was proposed on February 20, 1775 and dated on February 27.
The Conciliatory Resolution declared that any colony that contributed to the common defense and provided support for the civil government and the administration of justice (ostensibly against any anti-Crown rebellion) would be relieved of paying taxes or duties except those necessary for the regulation of commerce.
The resolution was addressed and sent to the individual colonies, and intentionally ignored the extralegal Continental Congress. By doing this, Lord North hoped to divide the colonists amongst themselves and thus weaken any revolution/independence movements (especially those represented by the Continental Congress). The resolution proved to be "too little, too late," and the American Revolutionary War began at Lexington on April 19, 1775.
