New freemen have to swear an oath to be ‘buxom’ to the mayor. This is a medieval way of declaring obedience and loyalty to the mayor.

Ed Balls’ ancestors were Norwich Freemen between 1404 and 1913, but the succession has lapsed and he is no longer eligible.

The freemen paid to build the city walls in the early 14th century. The idea was to defend the city from attack, but it was much more useful for collecting tolls.

Anybody who wished to trade freely in medieval Norwich had to become a freeman.
