being increasingly dependent on trade with England. A power struggle developed between Scotland and England in 1680s, as Scotland recovered from the political turmoil and set on its own economic ambitions, which London considered a threat to its dominant and well-established position. English wars with continental powers undermined Scottish trade with France and the Netherlands, countries that used to be the Scotland's main trade partners before the union, and the English Navigation Acts severely limited Scottish ability to trade by sea, and made the Scottish ambitions to expand the trade beyond Europe unachievable. Opinion in Scotland at the time was that England was sabotaging Scottish economic expansion. The frustration caused by economic and political rivalry with England led to the Darien scheme - an unsuccessful to establish a Scottish colony in the Gulf of Darién. Christopher Smout argues that the scheme was successfully sabotaged by England in various ways - it was seen as a threat to the privileged position of the East India Company, and as such England did everything to ensure the plan's failure via political and diplomatic overtures to prevent the Netherlands and Hamburg from investing into the scheme while also refusing to assist the settlers in any way. Following the disastrous failure of the scheme, Scottish economy seemed to be on the brink of collapse, but ultimately Scotland was able to recover from it fairly quickly. By 1703, Scottish government was highly disillusioned and unsatisfied with the union, and many believed that the only way to let Scottish economy flourish was to separate from England. Fletcher of Saltoun called Scotland 'totally neglected, like a farm managed by servants not under the eye of the master', and the failure of the Darien Scheme was commonly attributed to English sabotage. Scottish parliament would try to establish its autonomy from England with 1704 Act of Security, which provoked a retaliation from England - Scottish ministers were bribed, and Alien Act 1705 was passed. According to the Alien Act, unless Scotland appointed commissioners to negotiate for union by Christmas, every Scot in England would be treated as an alien, leading to the confiscation of their English estates. Additionally, Scottish wares were to be banned from England. Christopher Smout notes that England desired to expand its influence by annexing Scotland: The act sparked vehement anti-English sentiment in Scotland, and made the already hostile Scottish public even more opposed to England: The
