In 1903, Saint Patrick’s Day became an official public holiday in Ireland. This was thanks to the Bank Holiday (Ireland) Act 1903, an act of the United Kingdom Parliament introduced by Irish MP James O’Mara. O’Mara later introduced the law that required that pubs and bars be closed on 17 March after drinking got out of hand, a provision that was repealed in the 1970s. The first Saint Patrick’s Day parade held in the Irish Free State was held in Dublin in 1931 and was reviewed by the then Minister of Defence Desmond Fitzgerald. Although secular celebrations now exist, the holiday remains a religious observance in Ireland, for both the Roman Catholic Church and the Church of Ireland.

In the mid-1990s the Irish government began a campaign to use Saint Patrick’s Day to showcase Ireland and its culture. The government set up a group called St. Patrick’s Festival, with the aim to:

— Offer a national festival that ranks amongst all of the greatest celebrations in the world and promote excitement throughout Ireland via innovation, creativity, grassroots involvement, and marketing activity.

— Provide the opportunity and motivation for people of Irish descent, (and those who sometimes wish they were Irish) to attend and join in the imaginative and expressive celebrations.

— Project, internationally, an accurate image of Ireland as a creative, professional and sophisticated country with wide appeal, as we approach the new millennium.

The first Saint Patrick’s Festival was held on 17 March 1996. In 1997, it became a three-day event, and by 2000 it was a four-day event. By 2006, the festival was five days long; more than 675,000 people attended the 2009 parade. Overall 2009′s five day festival saw close to 1 million visitors, who took part in festivities that included concerts, outdoor theatre performances, and fireworks.

The topic of the 2004 St. Patrick’s Symposium was “Talking Irish,” during which the nature of Irish identity, economic success, and the future were discussed. Since 1996, there has been a greater emphasis on celebrating and projecting a fluid and inclusive notion of “Irishness” rather than an identity based around traditional religious or ethnic allegiance. The week around Saint Patrick’s Day usually involves Irish language speakers using more Irish during seachtain na Gaeilge (“Irish Week”).

As well as Dublin, many other cities, towns, and villages in Ireland hold their own parades and festivals, including Cork, Belfast, Derry, Galway, Kilkenny, Limerick, and Waterford.

The biggest celebrations outside Dublin are in Downpatrick, County Down, where Saint Patrick is rumoured to be buried. In 2004, according to Down District Council, the week-long St. Patrick’s Festival had more than 2,000 participants and 82 floats, bands, and performers and was watched by more than 30,000 people.

The shortest St Patrick’s Day parade in the world takes place in Dripsey, Cork. The parade lasts just 100 yards and travels between the village’s two pubs.

Christian leaders in Ireland have expressed concern about the secularisation of St Patrick’s Day. In The Word magazine’s March 2007 issue, Fr. Vincent Twomey wrote, “It is time to reclaim St Patrick’s Day as a church festival.” He questioned the need for “mindless alcohol-fuelled revelry” and concluded that “it is time to bring the piety and the fun together.”

He is said to have used the shamrock, a three-leaved plant, to explain the Holy Trinity to the pagan Irish, and the wearing and display of shamrocks and shamrock-inspired designs have become a ubiquitous feature of the day. In the 1798 rebellion, in hopes of making a political statement, Irish soldiers wore full green uniforms on 17 March in hopes of catching public attention. The phrase “the wearing of the green”, meaning to wear a shamrock on one’s clothing, derives from a song of the same name.

Two authentic letters from him survive, from which come the only universally accepted details of his life. When he was about 16 he was captured from Britain by Irish raiders and taken as a slave to Ireland, where he lived for six years before escaping and returning to his family. After entering the Church, he returned to Ireland as an ordained bishop in the north and west of the island, but little is known about the places where he worked.

By the seventh century he had come to be revered as the patron saint of Ireland. The Irish monastery system evolved after the time of Patrick and the Irish church did not develop the diocesan model that Patrick and the other early missionaries had tried to establish.

Most available details of his life are from later hagiographies from the 7th century onwards, and these are now not accepted without detailed criticism. Uncritical acceptance of the Annals of Ulster would imply that he lived from 340 to 440, and ministered in what is modern day Northern Ireland from 428 onwards. The dates of Patrick’s life cannot be fixed with certainty, but on a widespread interpretation he was active as a missionary in Ireland during the second half of the 5th century. Saint Patrick’s Day (17 March), supposedly the day of his death, is celebrated both in and outside of Ireland, as both a liturgical and non-liturgical holiday. In the dioceses of Ireland it is both a solemnity and a holy day of obligation and outside of Ireland, it can be a celebration of Ireland itself.

It is a public holiday in the Republic of Ireland, Northern Ireland, Newfoundland and Labrador and in Montserrat. It is also widely celebrated by the Irish diaspora, especially in places such as Great Britain, Canada, the United States, Argentina, Australia, New Zealand, and Montserrat, among others.
