This is one of a series of charters
which regulates trade at the Tiverton Market. The original charter, which permits the holding of a weekly market and annual fair, is dated 1257-58.

The market was originally held on a Monday, but this charter, dated
16 November 1655 and issued by Oliver Cromwell, changed the day to Tuesday. This followed a series of floods and fires, when it was believed that God was delivering a judgement on the inhabitants for setting up the market on the Sunday night - the sabbath day.
