The conclusion rejects a single-cause account of English intervention in Wales. Conquest and colonial expansion remain part of the explanation, while Welsh rulers repeatedly used civil conflict in England as an opening. Scottish alliances with France and England's proximity to Ireland place that pattern inside the security concerns of medieval kings. Coastal exposure and two land frontiers made neighboring political alignments directly relevant to English defense. Territorial ambition, political fragmentation, and hostile alliances all shaped the repeated English drive for control.
