If the pro-independence vote surges in this week's elections for the Scottish Parliament, momentum for an another referendum on independence may become unstoppable.
It has weathered the conquest and loss of an empire, survived two world wars and witnessed more than one deadly pandemic. But now Scotland's ancient alliance withEngland is itself in poor health and this week it could take a serious turn for the worse.
When Scottish voters go to the polls to elect 129 members of Scotland's Parliament, strictly speaking the question of independence will not be on the ballot.
Yet, Scotland is grappling with an uncertain future. Pressure is growing for a second referendum on whether to leave the United Kingdom, breaking up a 314-year-old union. If Scots vote in sufficient numbers for pro-independence parties in Thursday's election, the momentum for another plebiscite could become unstoppable.
The end of the union with England is no foregone conclusion, as Scotland is divided both over its future and the prospect of another polarising vote on independence.
Some are simply weary of the upheaval wrought by years of constitutional wrangling over an issue that divides families and friends as much as it does politicians.
Political parties that favor the union argue that, given the economic damage inflicted by the Covid-19 pandemic, it would be pure self-indulgence to embark now on another toxic independence debate, widely known as "indyref2."
After all, the question was supposed to have been settled for a generation in 2014 when 55 per cent of Scots who voted in a referendum opted to preserve their union with England, Wales and Northern Ireland.
But Brexit changed the calculus. In the 2016 referendum, 62 per cent of Scottish voters who took part opposed leaving the European Union, only to be outnumbered by their compatriots in England and Wales and wrenched, unwillingly, out of the trading bloc. That reinvigorated Scotland's independence movement, and called the country's constitutional future once again into question.
But Scotland's politics had been diverging from those of the rest of Britain for much longer. The majority of Scots have voted against the Conservatives in every general election for decades, yet they were powerless to prevent the party from taking power in eight of the 11 contests since 1979.
Brexit has reminded Scots that, no matter how they cast their ballots, they are just 8 per cent of Britain's population and are easily outvoted by their neighbours to the south. The embrace of Brexit by Prime Minister Boris Johnson's Conservatives reinforced that message.
Johnson not only proceeded with Brexit but brushed aside Scottish calls to keep close ties to the European Union and opted instead for a bare-bones free trade deal with the bloc that has caused significant disruption.
Among the sectors worst hit by Britain's departure from the EU's giant single market is the Scottish seafood industry. Many people in fishing communities like Peterhead bucked the trend in Scotland and voted for Brexit, lured by the promise of a "sea of opportunities" for their industry outside the EU's fisheries rules.
The reality has been a mountain of red tape hampering exports to the continent, leaving shellfish catches spoiled and boats tied up in harbours.
Both sides of the debate see lessons in that. The pro-independence Scottish National Party, led by the first minister, Nicola Sturgeon, points to the economic damage and says she would aim to rejoin the European Union after breaking away from England. In so doing Scotland could make a success of independence like other small nations like Ireland, which took that step a century ago.
Her critics say that this would pile more economic misery on top of Brexit by destroying the common economic market with England, easily Scotland's biggest trading partner. It would probably also mean a physical trade border between England and Scotland, a frontier that is in some places hard even to spot.
Nonetheless, the 2016 Brexit referendum showed that appeals to emotion can trump those to the wallet. In Scotland, identity issues have grown within a proud nation that always maintained a separate, some would say superior, legal and educational system.
Sturgeon's SNP is aiming for a rare overall majority in the Scottish Parliament to justify her calls for a second independence referendum. Failing that, she hopes that votes for other pro-independence parties, especially the Greens, will be enough to bolster her case.
Support for independence in opinion polls peaked last year at above 50% while Sturgeon's handling of the pandemic looked sure-footed at a time when Johnson's seemed chaotic.
But the successful rollout of the Covid-19 vaccine — for which Johnson can take credit — has coincided with a slight dip in Sturgeon's fortunes. Also campaigning in Thursday's election is Alex Salmond, a veteran of the pro-independence cause but now a sworn enemy of Sturgeon who was once his protégé. The two politicians fell out over Sturgeon's role in a bungled investigation into allegations against Salmond of sexual misconduct.
After months of feuding with her former mentor, Sturgeon survived a damaging crisis but Salmond has formed a new pro-independence party, Alba.
There are domestic issues at stake too and, after 14 years in power in Edinburgh, the SNP has many critics in Scotland. In TV debates, Sturgeon has been forced to defend her record on everything ranging from educational achievement to Scotland's poor record on drug deaths.
In the Shetland Islands, some voters feel as remote from Sturgeon's government in Edinburgh as from Johnson's in London, and there is even talk of the islands opting for independence from Scotland.
On the mainland, the mood is uncertainty. For Sturgeon tough questions lie ahead about whether an independent Scotland could afford the sort of social policies she favors without the support of taxpayers in England or their central bank.
Noticeably absent is Johnson, who has stayed away from Scotland, knowing that his presence would probably undercut the Conservative Party's pitch to preserve the union. Educated at Britain's most famous high school, Eton College, and then Oxford University, Johnson's cultivated English upper-class persona tends to grate on Scottish voters.
Despite his absence, the stakes are for high for Johnson. The loss of Scotland would deprive the United Kingdom of about a third of its landmass and significant international prestige.
It would also likely mean the closure of the Faslane nuclear submarine base that the SNP opposes, believing its location makes the nearby city of Glasgow a military target.
Were Johnson to lose a Scottish independence referendum, he would probably have to resign, and his strategy has simply been to reject calls for one. For a plebiscite to be legally binding, an agreement almost certainly would have to first be struck with London, and the prime minister can continue to stonewall for some time.
But whatever the law, it's hard to say no indefinitely. And a centuries-old union could face its greatest test if a majority in Scotland, which joined voluntarily with England in 1707, thinks now is the time to think again.
