Born in Glasgow in 1904, Dr John MacCormick studied law at Glasgow University and was one of the chief founding members of the National Party of Scotland in 1928 and, with the merger of the NPS and the Scottish Party, of the Scottish National Party in 1934. In 1942, he left the SNP and was instrumental in the forming the Scottish Convention which went on to produce the Scottish Covenant in 1949, upon which nearly two million signatures of support for a Scottish parliament were obtained.

After a high-profile trip to the US and Canada to present Scotland's case for Home Rule he was voted Lord Rector at Glasgow University. During his stint in this position he became involved in the plot to steal the Stone of Destiny from Westminster Abbey before going on to publish The Flag in the Wind in 1955.

With a new introduction by the author's son, this updated edition of John MacCormick's seminal work examines the early years of the twentieth-century Nationalist movement in Scotland, providing an invaluable insight into people and events that help create and then shape the SNP and its campaign to secure a devolved Scottish Assembly.
