The term Yamnat was mentioned in Old South Arabian inscriptions on the title of one of the kings of the second Himyarite kingdom known as Shammar Yahrʽish II. The term probably referred to the southwestern coastline of the Arabian peninsula and the southern coastline between Aden and Hadramout. The historical Yemen included much greater territory than the current nation, stretching from northern 'Asir in southwestern Saudi Arabia to Dhofar in southern Oman.
