During World War II, thousands of indigenous Liberians migrated from the nation's rural interior to the coastal regions in search of jobs. The Liberian Government had long opposed this kind of migration, but was no longer able to restrain it. In the decades after 1945, the Liberian government received hundreds of millions of dollars of unrestricted foreign investment, which destabilized the Liberian economy. Government revenue rose enormously, but was being grossly embezzled by government officials. Growing economic disparities caused increased hostility between indigenous groups and Americo-Liberians.
