The eventual Reformation of the Scottish Church followed a brief civil war in 1559–60, in which English intervention at the siege of Leith on the Protestant side was decisive. A Reformed confession of faith was adopted by Parliament in 1560, while the young Mary, Queen of Scots, was still in France. The most influential figure was John Knox, who had been a disciple of both John Calvin and George Wishart. Roman Catholicism was not totally eliminated, and remained strong particularly in parts of the highlands.
