As a unified entity, Clan Buchanan took no part in the Jacobite uprisings of 1715 to 1716 or the 1745 to 1746 uprising. A likely contributing factor was the leadership vacuum resulting from the death of the last Chief in c1681. There is clear evidence of some Buchanans supporting the Jacobite cause (including the reintroduction of the absolute monarchy of the Stuarts) while others were supporting the Government cause (including the continuance of the limited monarchy of the Hanoverians: limited by law and Parliament).
