the Darien scheme was an abject failure -
The failure of the Darien colonization project has been cited as one of the motivations for the 1707 Acts of Union.
According to this argument, the Scottish establishment realised that it could never be a major power on its own and that if it wanted to share the benefits of England's international trade and the growth of the English Empire, then its future would have to lie in unity with England. More so, Scotland's nobles were almost bankrupted by the Darien fiasco.
Some Scottish nobility petitioned Westminster to wipe out the Scottish national debt and stabilise the currency. The first request was not met though the second was and a Scottish Pound was given the fixed value of a shilling. Personal Scottish financial interests were also involved. Scottish commissioners had invested heavily in the Darien project and they believed that they would receive compensation for their losses. The 1707 Acts of Union, Article 14, granted £398,085 10s sterling to Scotland to offset future liability towards the English national debt.
