Upon the death of his father in 1616, he became the 10th Lord Lindsay of the Byres. In 1633, he was created
Earl of Lindsay. He also received the earldom of Crawford following the forfeiture of his cousin,
Ludovic Lindsay, 16th Earl of Crawford, in November 1652 (under the terms of the 1641/2 regrant of the Earldom of Crawford). He became
Treasurer of Scotland in 1644, and in 1645
President of Parliament. During the
Wars of the Three Kingdoms he played a complex role, but his position was basically a moderate Presbyterian "Engager" one. He fought for the army of the Scots Parliament at the
Battle of Marston Moor, and against the royalist general Montrose at the
Battle of Kilsyth, and was eventually captured by the English at
Alyth. He then changed sides, and in 1647 he signed the "engagement" for the release of
Charles I, losing all his offices when his enemy, the
Marquess of Argyll, obtained the upper hand. After the defeat of the Scots at the
Battle of Dunbar in 1650, however, Crawford regained his influence in Scottish politics, but from 1651 to 1660 he was a prisoner in England following his capture at
Alyth in an incident known as 'the Onfall of Alyth'. In 1661 he was restored to his former dignities, but his refusal to abjure the covenant compelled him to resign them two years later. ==Personal life==
