An attempt by Charles to impose his authority led to the first First Bishops' War in 1639. The Covenanters defeated Royalist forces in Aberdeenshire, consolidating their control of Scotland, while the chaotic state of the English army meant they were no match for the more experienced Scots. While the two sides agreed the Treaty of Berwick in June, both saw it primarily as an opportunity to strengthen their position. In April 1640, Charles recalled Parliament for the first time in eleven years; when it refused to vote taxes without concessions, he dissolved it after only three weeks.
