Colonial troops could be used to garrison or subdue other territories than those in which they were recruited to avoid problems of conflicting loyalties. For example, Italy used Eritrean askaris in Libya and during both wars with Ethiopia (1895 and 1936). Indian regiments garrisoned Aden, Singapore and Hong Kong at various times in the 19th and the early 20th centuries. In the 1950s, the Portuguese used African troops from Mozambique to garrison Goa, and the Dutch had West Africans (Zwarte Hollanders) for service in the East Indies during much of the 19th century.
