 The Presbyterian Scots were joined in the mid-19th century by displaced Irish potato famine refugees who were forced to take poorer land in surrounding areas.Political, social and economic tensions between the Roman Catholic Irish and Presbyterian Scots boiled over during a general election in March 1847, resulting in what has become known as the Belfast Riot.Today, Belfast is known for its golf course Belfast Highland Greens, Mini Woolen Mills, and many art studios and pottery shops.
