At the time, Germans tended to cluster more than other immigrants, such as the Irish, and in fact those from particular German states preferred to live together. This choice of living in wards with those from the same region was perhaps the most distinct and overlooked feature of "Kleindeutschland". For instance the Prussians, who by 1880 accounted for nearly one-third of the city's German-born population, were most heavily concentrated in the city's Tenth Ward. Germans from Hessen-Nassau tended to live in the Thirteenth Ward in the 1860s and in the ensuing decades moved northward to the borders of the Eleventh and Seventeenth Wards. Germans from Baden by the 1880s tended to favor living in the Thirteenth Ward, and Wurttembergers began by the 1860s to migrate northward into the Seventeenth Ward. The Bavarians (including Palatines from the Palatinate region of western Germany on the Rhine River, which was subject to the King of Bavaria), the largest group of German immigrants in the city by 1860, were distributed evenly in each German ward except the Prussian Tenth. Aside from the small group of Hanoverians, who had a strong sense of self-segregation forming their own "Little Hanover" in the Thirteenth Ward, the Bavarians displayed the strongest regional bias, mainly toward Prussians: at all times the most distinctive characteristic of their settlement pattern remained that they would be found wherever the Prussians were fewest.
