Question

What was a Cornish stannary court?

Short answer

It was a powerful specialist court applying mining law to Cornwall and Devon's tin industry, alongside a broader stannary political structure.

Notes

Stannary courts were specialist legal institutions for tin miners in Cornwall and Devon. They applied stannary law to disputes and standards in an industry whose value sometimes made Cornwall one of the richest parts of the kingdom. Their authority could extend to imprisoning members of Parliament, and a related stannary legislature represented mining interests. The panel links their durability to both the economic importance of tin and medieval struggles with King John, where support from William Marshal strengthened the local position.
