Macha

Macha appears under several guises across Irish tradition, but her most famous story is the Ces Noínden, "the Debility of the Ulstermen." Married to a wealthy farmer named Crunniuc, Macha lives with him on the condition that he never mention her existence at court. Crunniuc breaks the promise, boasting at an assembly before King Conchobar mac Nessa that his wife can outrun the king's own horses. Conchobar has Macha brought to court, heavily pregnant, and forces her to race the chariot team or see her husband killed. She wins the race, but collapses at the finish line and gives birth to twins on the spot — and with her last strength, curses the men of Ulster to suffer labor pains at their moment of greatest need, for five days and four nights, for nine generations to come. That curse becomes the hinge of the Táin Bó Cúailnge: when Medb of Connacht invades Ulster, the curse strikes every grown warrior in the province at once, leaving only the teenage Cú Chulainn — spared because of his divine parentage — able to defend the border alone. Emain Macha, the great royal seat of Ulster near modern Armagh, is traditionally said to take its name from her, either from this same Macha or from an earlier queen of the same name credited with founding the site. Macha is sometimes also numbered among the shifting triad of war-goddesses alongside Badb and the Morrígan (or Nemain), reflecting how fluid these figures' identities are across different manuscripts — the same name can refer to more than one goddess, or one goddess wearing more than one name, depending on the source.
