Mudiad Amddiffyn Cymru (Welsh for 'movement for the defence of Wales', pronounced [ˈmɨːdjad amˈðiːfɨn ˈkəmrɨ]; abbr. MAC) was a paramilitary Welsh nationalist organisation, which was responsible for a number of bombing incidents between 1963 and 1969. The group's activities primarily targeted infrastructure transporting water to the English cities of Birmingham and Liverpool, in addition to the investiture of Charles III as Prince of Wales.
