[4] In total, 23,889 people of German birth or descent lived in the city, comprising 17.1% of the foreign-stock white population.
[5] As of 2000, 18.7%, or 478,646, of the Baltimore metropolitan area's population were of German descent, making it the largest European ancestral group.
[8] German immigrants began to settle along the Chesapeake Bay by 1723, living in the area that became Baltimore when the city was established in 1729.
[12] This wave of immigrants created numerous German institutions, including banks, insurance companies, and newspapers.
By the time of the American Civil War, there were 32,613 German-born residents of Baltimore, not counting their American-born descendants of first generation along with the earlier wave of colonial and pre-revolutionary era settlers.
The population continued to surge after the Civil War, due in large part to the agreement signed on January 21, 1867 between the Baltimore and Ohio Railroad and the Norddeutscher Lloyd, a German steamship line which brought tobacco along with further German immigrants to the port of Baltimore from Bremen, Germany.
[15] By 1868, one-fourth of Baltimore's 160,000 white inhabitants were German-born and half of the remainder were of full or partial German descent.
[19] Holy Cross Church on West Street off Light Street in old South Baltimore near Federal Hill was founded in 1860 to serve the growing numbers of Germans moving onto the peninsula south of "The Basin" of the Patapsco River's Northwest Branch and the Baltimore Harbor, which had been annexed into the city in 1816.
St. Elizabeth of Hungary Roman Catholic was later founded in 1895 in Highlandtown in east Baltimore to serve the German immigrant community in that part of the city.
By the 1920s, one third of Baltimore's public schools still offered German-language curricula and a quarter of Baltimoreans could still speak German fluently.
The church had historically played an important institutional role for South Baltimore's large German community.
