German Nicaraguan is a Nicaraguan having German ancestries or a German naturalized Nicaraguan. This includes Poles due to Partitions of Poland. During the Second World War, after Nicaragua's allies declared war on Germany, German immigrants not naturalized were persecuted and imprisoned. Some were deported to Germany or to concentration camps in other countries. Although Germans have emigrated to Nicaragua since the 19th century, most of the German Nicaraguans still speak both Spanish and German.
