国民盟約
After the Kirk Party seized power from the unsuccessful and therefore discredited Engagers, the new Scottish Covenanter government persuaded the exiled Charles II to agree to the terms of the "Solemn League and Covenant" in the Treaty of Breda (1650). However, the defeat of the Royalist and Scottish army at the Battle of Worcester in 1651 ended the relevance of the "Solemn League and Covenant" as the power of the Presbyterians was broken on both sides of the border.
