Ethnic history The earliest known inhabitants of the St. Paul area, from about 400 AD, were members of the Hopewell tradition, who buried their dead in mounds on the river bluffs (now Indian Mounds Park). The next known inhabitants were the Mdewakanton Dakota in the 17th century, who fled their ancestral home of Mille Lacs Lake in central Minnesota in response to westward expansion of the Ojibwe nation. The Ojibwe later occupied the north (east) bank of the Mississippi River. By 1800, French-Canadian explorers came through the region and attracted fur traders. Fort Snelling and Pig's Eye Tavern also brought the first Yankees from New England and English, Irish, and Scottish immigrants, who had enlisted in the army and settled nearby after discharge. These early settlers and entrepreneurs built houses on the heights north of the river. The first wave of immigration came with the Irish, who settled at Connemara Patch along the Mississippi, named for their home, Connemara, Ireland. The Irish became prolific in politics, city governance, and public safety, much to the chagrin of the Germans and French, who had grown into the majority. In 1850, the first of many groups of Swedish immigrants passed through St. Paul on their way to farming communities in northern and western regions of the territory. A large group settled in Swede Hollow, which later became home to Poles, Italians, and Mexicans.
