The Acts of Union 1707 brought together England and Scotland, ‘United into One Kingdom by the Name of Great Britain’. But the historian Karin Bowie tells Andrew Marr that in the years preceding a growing number of pamphlets and demonstrations showed that many people were divided on the issue. In ‘Public Opinion in Early Modern Scotland c.1560–1707’ Bowie charts the growing debate across society. The failure of Scotland’s trading ambitions in the Darien Scheme also hit the country hard, both financially and emotionally.

However the idea of an independent Scotland emerged surprisingly recently into public debate, according to academic Ben Jackson. In his book The Case for Scottish Independence he argues that an influential Scottish nationalism only began to take shape from the 1970s onwards. It was at heart a political project, born out of opposition to the Thatcher government.

Ruth Wishart is a pro-independence journalist who has written about Scottish affairs for many decades. As s columnist for The National she is following every twist and turn as Scottish nationalists agitate for a second independence referendum to follow the Scottish Parliament election in May.

The political scientist Ailsa Henderson will be watching the coming elections closely too as she’s an expert on voting behaviour and attitudes to both Scottish and English nationalism. A number of Scots felt a deep sense of grievance against their neighbours at the formation of the Union. Now more than three hundred years later Henderson shows, in her forthcoming book Englishness – co-written with Richard Wyn Jones – that English nationalism contains a strain of grievance about England’s place within the United Kingdom.
