It was among Irish American communities that the day became the celebration it is, from its roots as a more solemn day with a religious observance in Ireland.

The spread of St. Patrick’s Day celebrations in the U.S. was a way for Irish immigrant communities, who in the 19th century faced discrimination and opposition, to stake that ground, he says: “It’s a kind of immigrant Irish way of combating nativist antagonism against them.”

St. Patrick's Day is celebrated annually on March 17 in honor of the patron saint of Ireland. While not a federal or state holiday in Michigan, many cities hold parades and events to celebrate Irish heritage.

The day kicks off Sunday with local musicians, dancers, artists and storytellers. The celebration is a longstanding tradition that has taken place each St. Patrick’s Day at the Landmark Center for more than 40 years and draws thousands of people into downtown St.

Hundreds of people participated in the St. Patrick's Day Parade Sunday, ahead of a holiday meant to celebrate Irish culture.
