Bosnian Americans are Americans whose ancestry can be traced to Bosnia and Herzegovina. The vast majority of Bosnian Americans immigrated to the United States during and after the Bosnian War which lasted from 1992–95. Nevertheless, many Bosnians immigrated to the United States as early as the 19th century. The largest Bosnian American population can be found in St. Louis, Missouri, which boasts the largest number of Bosnians in the world outside Europe.
