Irish people
The population of Ireland is about 6.3 million, but it is estimated that 50 to 80 million people around the world have Irish forebears, making the Irish diaspora one of the largest of any nation. Historically, emigration from Ireland has been the result of conflict, famine and economic issues. People of Irish descent are found mainly in English-speaking countries, especially Great Britain, the United States, Canada and Australia. There are also significant numbers in Argentina, Mexico and New Zealand. The United States has the most people of Irish descent, while in Australia those of Irish descent are a higher percentage of the population than in any other country outside Ireland. Many Icelanders have Irish and Scottish Gaelic forebears.

Many Irish people were also transported to the island of Montserrat, to work as indentured servants, exiled prisoners or slaves. Unlike African chattel slaves, the majority of Irish labourers who were sent to Montserrat did so by personal choice although they were tricked into doing so by the promise of payment and land of which they did not receive. Some were exiled by the English Oliver Cromwell due to the large Irish population and their attempted rebellion on 17 March 1768. To this day, the Island celebrates St. Patrick's Day as a public holiday to commemorate the event. People of Irish descent also feature strongly in Latin America, especially in Argentina and important minorities in Brazil, Chile, and Mexico. In 1995, President Mary Robinson reached out to the "70 million people worldwide who can claim Irish descent". Today the diaspora is believed to contain an estimated 80 million people.
There are also large Irish communities in some mainland European countries, notably in Spain, France and Germany. Between 1585 and 1818, over half a million Irish departed Ireland to serve in the wars on the Continent, in a constant emigration romantically styled the ""Flight of the Wild Geese"" and, before that, in the 'Flight of the Earls', just before the Plantation of Ulster. In the early years of the English Civil War, a French traveller remarked that the Irish "are better soldiers abroad than at home". Later, Irish brigades in France and Spain fought in the Wars of the Spanish and Austrian Succession and the Napoleonic Wars. In the words of Field Marshal The 1st Duke of Wellington, the Irish-born 'Iron Duke', a notable representative of the Irish military diaspora, "Ireland was an inexhaustible nursery for the finest soldiers".
