On March 17, people around the world celebrate the Irish holiday of Saint Patrick's Day. It is a major holiday in Ireland, but the rest of the world has influenced its celebration as much as the Irish themselves.

Most Americans think of Saint Patrick's Day as a big party centered around drinking alcohol. But its beginnings in Ireland were religious, says Mike Cronin, a professor of Irish history with Boston College of Massachusetts.

Ireland is a mostly Roman Catholic country. Saint Patrick lived in Ireland more than 2,000 years ago. He is widely considered to have established Christianity in the country. The Church honored him with a holy day in the 17th century. March 17 marks the date of his death. The average Irish person honored March 17 quietly. Attending church services was the main activity. In fact, most businesses that served alcohol would close in honor of the day.

In the early 1900s, Ireland's government made St. Patrick's Day an official holiday. By the 1960s, towns across Ireland started celebrating the holiday with parades and music. In Ireland today, St. Patrick's Day is a four-day public celebration that includes parades, music, food, and games.

For Irish people living outside Ireland, Saint Patrick's Day became a chance to celebrate their Irish identity and culture. Now, countries and cities around the world celebrate March 17 in creative ways. Many countries hold Saint Patrick's Day parades. Famous monuments, including the Great Wall of China, the Niagara Falls, and the Gateway of India in Mumbai will all be colored by green light for the day.

Cronin says that the worldwide popularity of Saint Patrick's Day has helped the Irish government, which uses the holiday as a form of diplomacy(外交). And for a small island of 4.5 to 5 million people it's quite remarkable that they have that kind of soft power.
