The Cornish Stannary Parliament (officially The Convocation of the Tinners of Cornwall)[1] was the representative body of the Cornish stannaries, which were chartered in 1201 by King John.[2] In spite of the name, the Parliament was not a Cornish national assembly, instead representing the interests of the tin industry; however, due to the significant proportion of Cornwall's population involved in the tin trade, it wielded considerable power.[1][3]
