Tell me why the English built all those forts in the highlands. They were built to keep the local population in check and that is the only reason.
Three, to be exact - only one of which, Fort William (named after William of Orange) was built before the Union, Fort George and Fort Augustus being built after the 1715 Jacobite uprising. Whilst they were indeed there to keep the local population, i.e. the Highland clans, under control, this move was welcomed by the Lowland Scots because they were fed up with raids and pillaging carried out on them by the Highlanders who managed on several occasions to get as far as Edinburgh. Also a great number of Highlanders were Roman Catholics who wanted to see the exiled Catholic James II back on the throne - something the Lowlanders, who were mainly Presbyterians and Episcopalians, did not want and so favoured the Protestant succession.
I still maintain that the ordinary population were against the union martial law would have been Invoked causing the deaths of many people. .
I did actually say in my post that many of the ordinary population were against the Union, this being largely due to the fact that they didn't really know or understand what was going on between the Scottish and English Parliaments, which was hardly surprising given that the only way news could be spread then was by means of pamphlets - and there was no shortage of these, all of them containing conflicting information about the Union which had been picked up second or even third hand, because in those days there was no such thing as parliamentary reporters either in Scotland or England and so the only reports came from people who had managed somehow to sneak in and hide (up chimneys was a favourite place) and listen to the debates. There were many riots, something which caused the authorities to declare meetings of large numbers of people a punishable offence. This, however, didn't stop serious rioting from taking place in Edinburgh whilst the negotiations were in progress, and on at least one occasion the lives of members of parliament, mainly the nobility, were under threat and Parliament House itself invaded. The local militia were called upon to deal with these, and no doubt deaths did occur, but the amount of bloodshed was surprisingly little in the circumstances.
As Robert Burns said "We're bought and sold for English gold. Such a parcel of Rogues in a nation"
I have great admiration for Burns but he too, like the majority of the population, was pretty ignorant as to what was going on, and like so many others pounced on the Equivalent for his pronouncement.
As for the parcel of Rogues statement, I don't deny that some of the nobility were quite keen to further their own ambitions, but the main reason behind the Union was that Scotland was a seriously impoverished country, something which was aggravated by the ill-advised and ill-fated Darien Scheme, and so a little help from England was necessary, particularly regarding trading. There had been three previous attempts to start union negotiations in the years following the 1603 Regal Union, but all had failed due to lack of interest on both sides. Now it was the Scottish Parliament which was pushing for it for the reason stated. Also not all the nobility were in favour of the Union. In fact Scotland's premier Duke, the Duke of Hamilton, was violently opposed to it, although even he was quick to change his mind after the Treaty was in place.
