For the 1800s decade, it’s impossible to ignore the war with France as a constant drumbeat, even in the brief Amiens peace, the sudden return of soldiers and looming restart of war coloured everything.

By 1805, everyone would know of Trafalgar and Nelson’s death. Trade restrictions, shortages, and smuggling were daily realities. And from 1807 on, the end of the slave trade was a landmark moment felt in sermons, newspapers, and conversations across all levels of society.
