Ireland is divided between the Republic of Ireland and Northern Ireland, with a total population of 6.4 million people. Some key symbols of Ireland include the shamrock and harp, while sports such as rugby and soccer are popular, though Ireland has never won a world cup in either. The weather is typically cold and rainy, keeping temperatures below 22 degrees even in summer, which contributes to Ireland's lush green landscape and nickname as the Emerald Isle. Saint Patrick is also an important figure who brought Catholicism to Ireland after initially escaping.
