and extended the corresponding English law across Great Britain. Evaluations Scotland benefited, says historian G.N. Clark, gaining "freedom of trade with England and the colonies" as well as "a great expansion of markets". The agreement guaranteed the permanent status of the Presbyterian church in Scotland, and the separate system of laws and courts in Scotland. Clark argued that in exchange for the financial benefits and bribes that England bestowed, what it gained was of inestimable value. Scotland accepted the Hanoverian succession and gave up her power of threatening England's military security and complicating her commercial relations ... The sweeping successes of the eighteenth-century wars owed much to the new unity of the two nations. By the time Samuel Johnson and James Boswell made their tour in 1773, recorded in A Journey to the Western Islands of Scotland, Johnson noted that Scotland was "a nation of which the commerce is hourly extending, and the wealth increasing" and in particular that Glasgow had become one of the greatest cities of Britain. Economic perspective Scottish historian Christopher Smout notes that prior to the Union of the Crowns, the Scottish economy had been flourishing completely independently of the English one, with little to no interaction between each other. Developing a closer economic partnership with England was unsustainable, and Scotland's main trade partner was continental Europe, especially the Netherlands, where Scotland could trade its wool and fish for luxurious imports such as iron, spices or wine. Scotland and England were generally hostile to each other and were often at war, and the alliance with France gave Scotland privileges that further encouraged developing cultural and economic ties with the continent rather than England. The union of 1603 only served the political and dynastic ambitions of King James and was detrimental to Scotland economically – exports that Scotland offered were largely irrelevant to English economy, and while the Privy Council of Scotland did keep its ability to manage internal economic policy, the foreign policy of Scotland was not in hands of England. This limited Scotland's hitherto expansive trade with continental Europe, and forced it into English wars. While the Scottish economy already suffered because of English wars with France and Spain in 1620s, the civil wars in England had a particularly disastrous effect on Scotland and left it relatively impoverished as a result. The economy would slowly recover after that, but it came at the cost of
