Saint David () is said to have been born to
Saint Non at
Caerfai, southwest Wales. He was reportedly a
scion of the royal
house of Ceredigion, and founded a number of monastic communities in his early life before establishing his most notable community in
Meneva, at the "Glyn Rhosyn" (English: Vale of Roses), the location where
St Davids Cathedral stands today. David became well known for his wisdom as a teacher and for his life as an
ascetic and gained great renown throughout
Celtic Christianity, with the founding of some 1,200 Christian communities that are attributed to him or his followers. with his foundation at Meneva (now called St Davids in English) quickly becoming an important
shrine and site of pilgrimage after his death. The feast day of Saint David on 1st March has been celebrated since at least the 10th century according to the
Medieval Welsh literature such as the
Annales Cambriae, with Saint David being widely recognised as the patron saint of Wales since at least the 12th century David was canonised in the Catholic church by
Pope Callixtus II in 1120, thanks to the accession of
Bishop Bernard, the first Norman bishop of Saint Davids and thus March 1st becoming an official celebration in the Catholic calendar. During the
War of the Roses in the 15th-century the celebration of Saint David, his flag and his feast day took on a new meaning following the landing of an invasion force at Mill Bay near
Dale, Pembrokeshire. The invasion's leader was
Henry Tudor, who linked his
Welsh ancestry and used
Welsh symbols such as Saint David's Feast Day during his march through Wales to encourage Welsh patriotism and gather support to his banner (a
Welsh Dragon). In doing so, Henry amassed an army of about 5,000–6,000 soldiers which, though still outnumbered, decisively defeated
Richard III of England at the
Battle of Bosworth Field on 22 August 1485. The 17th-century diarist
Samuel Pepys noted how Saint David's Day celebrations by the Welsh in London would spark anti-Welsh counter-celebrations, including the burning and symbolic
lynching of life-sized effigies of Welshmen. By the 18th century, these customs continued and developed into English traditions such as the making of "taffies", an English confection where
gingerbread figures are baked in the shape of a Welshman riding a goat. ==Celebration and traditions==
