On this day in 1679, Archbishop James Sharp, Primate of Scotland, was attacked and killed.

The murder happened while he was travelling through Fife to St Andrews. The attackers were probably waiting for the Sheriff of Fife, but were happy to kill instead the man leading the forces suppressing the Covenant in Scotland. It sparked a wider uprising, leading to what is known as the "Killing Time".

Today in 1860, John Haldane, Scottish physician and physiologist, was born.
