People immigrated to Scotland in the 1800s-early 1900s for several reasons: 1) To escape poverty caused by events like the Irish Potato Famine and lack of opportunities in their home countries of Ireland, Italy, and Lithuania. 2) To find employment, as Scotland had jobs available in industries like farming, factories, and migrants also started their own businesses. 3) To avoid religious and political persecution, like Jews fleeing pogroms in Russia and Eastern Europe, and Lithuanians escaping Russian rule. 4) As a temporary stop on the way to their ultimate destination of the United States, since Scotland provided opportunities to earn money for transatlantic travel.
