The basic political unit of ancient Ireland was the tuath. All “freemen” who owned land, all professionals, and all craftsmen, were entitled to become members of a tuath. Each tuath’s members formed an annual assembly which decided all common policies, declared war or peace on other tuatha, and elected or deposed their “kings.” An important point is that, in contrast to primitive tribes, no one was stuck or bound to a given tuath, either because of kingship or of geographical location. Individual members were free to, and often did, secede from a tuath and join a competing tuath.
