Query: Between what years did Alatians begin to sail towards the United States?
Context: Thus, it is not surprising that people left Alsace, not only for Paris – where the Alsatian community grew in numbers, with famous members such as Baron Haussmann – but also for more distant places like Russia and the Austrian Empire, to take advantage of the new opportunities offered there: Austria had conquered lands in Eastern Europe from the Ottoman Empire and offered generous terms to colonists as a way of consolidating its hold on the new territories. Many Alsatians also began to sail to the United States, settling in many areas from 1820 to 1850. In 1843 and 1844, sailing ships bringing immigrant families from Alsace arrived at the port of New York.
