The Libyan Desert is the desert that forms the northern and eastern part of the Sahara Desert. It refers to the part of the Sahara that is in present-day Libya; it also historically describes the desert south of Ancient Libya, a region east of the present-day state. The Libyan Desert is one of the driest, harshest and most remote regions of the Sahara, the world's largest hot desert. This vast desert country is barren, arid and rainless.
