Erin go bragh! St Patrick's Day is here, with events in honour of the patron saint of Ireland taking place across the globe this weekend. Recognised annually since the 1700s, the people of Ireland celebrate their heritage and culture on St Patrick's Day, with the day growing as a commercial occasion rather than a religious event in recent years. While Ireland embraces its patron saint day by holding vibrant, green parades, wearing shamrocks and flying Irish flags more than usual, celebrations also take place in other countries around the world, including the UK, United States, Egypt and Australia. Here is everything you need to know about St Patrick's Day, from the patron saint himself to Irish recipes and worldwide celebrations. When is St Patrick's Day 2019? St Patrick's Day, the patron saint day of Ireland, falls each year on March 17. The first parade in name of the saint took place in Boston in 1737, followed by the first "official" parade in New York in 1766. The celebration of St Patrick later spread to Dublin and other American cities and in recent years has grown in popularity elsewhere in Europe and Asia. Who was St Patrick? St Patrick's exact birthplace is unknown and debated. Born as Maewyn Succat around the year of 385 AD in either England, Scotland or Wales, the patron saint was captured by Irish pirates at the age of 16 and brought to Ireland as a slave. Working as a shepherd, Patrick was held captive for six years and grew closer to spirituality and prayer during this period of isolation. After a voice in his dream told him it was time to leave Ireland, Patrick successfully fled his master and sailed back to Britain to continue studying Christianity. Shortly after his return home, an angel in Patrick's dream told him to go back to Ireland as a missionary, and following this, he decided to travel to Gaul, to study religious instruction under Germanus, bishop of Auxerre. Later ordained a bishop and eventually returning to Ireland, Patrick began his mission to spread the Christian message. During this time, Patrick converted thousands of people to Christianity and built churches, schools and monasteries across the country. Legend suggests that Patrick used the three-leaf shamrock on his mission to explain the Holy Trinity, teaching his followers that the Father, the Son and the Holy Spirit exist as individual elements of the combined entity. While some experts claim this story was invented centuries later, the tale has led to the common practice of people wearing the symbol on the feast day. Patrick is also thought to have banished snakes from Ireland to help remove the evil and introduce a new age. But experts claim this is a myth due to evidence snakes never existed in the country in the first place. Some say this was due to the icy waters of the Irish Sea while others believe the cold weather stopped the snakes travelling to Ireland from Britain or afar. Around 431 AD, Patrick was appointed as successor to St Palladius, the first bishop of Ireland, and during his later years, he wrote about his spirituality and life in his 'Confession'. Believed to have died on March 17, in the year 461, Patrick's spiritual path led him to become a legendary figure, as he left behind an established church and an island of Christians. Today, his work is commemorated annually on March 17. Symbols and images associated with Ireland and St Patrick's Day The colours of the Irish flag represent Catholicism (green) and Protestantism (orange), unified by peace (white). Since the 18th century, green has also represented sympathy for Irish independence. Despite St Patrick popularising shamrocks, with many choosing to wear them on the patron saint day, he is historically associated with the red Saltire of St Patrick, featured in the flag of the United Kingdom. The patron saint of Ireland is also associated with the colour blue, after the creation of the Order of St Patrick in the 1780s made it the official colour. “St Patrick’s Blue” can be found on Ireland's Presidential Standard, and in the plume of bearskins worn by the Irish Guards. The legend of the Leprechaun has also become a modern day symbol of Ireland. Known for their mischievous behaviour and leaving pots of gold at the end of rainbows, today, the mythical creatures feature heavily as a tourist symbol and some people choose to wear Leprechaun costumes and hats to St Patrick's Day parades. Dublin even has its very own Leprechaun Museum.
