It remembers St Patrick, a missionary who converted many of Ireland’s inhabitants to Christianity in the 5th century. His feast day also celebrates Irish culture.
People who have an Irish background or enjoy Irish culture may hold Irish themed parties and serve traditional dishes, such as Colcannon or Irish stew. Colcannon is a dish of mashed potatoes mixed with kale or cabbage and Irish stew is traditionally made with lamb and root vegetables. Traditional Irish drinks include stout, a dark beer, and whiskey. Other parties may be themed around the color green. Guests may be expected to wear green clothes and only green food and drink is served.
