Gilead or Gilad (Hebrew: גִּלְעָד Gīləʿāḏ, Arabic: جلعاد, Ǧalʻād, Jalaad) is the ancient, historic, biblical name of the mountainous northern part of the region of Transjordan. The region is bounded in the west by the Jordan River, in the north by the deep ravine of the river Yarmouk and the region of Bashan, and in the southwest by what were known during antiquity as the “plains of Moab”, with no definite boundary to the east. In some cases, “Gilead” is used in the Bible to refer to all the region east of the Jordan River. Gilead is situated in modern-day Jordan, corresponding roughly to the Irbid, Ajloun, Jerash and Balqa Governorates.

The Western United States (also called the American West, the Far West, and the West) is the region comprising the westernmost states of the United States. As American settlement in the U.S. expanded westward, the meaning of the term the West changed. Before about 1800, the crest of the Appalachian Mountains was seen as the western frontier. The frontier moved westward and eventually the lands west of the Mississippi River were considered the West.

The Chad Basin is the largest endorheic basin in Africa, centered on Lake Chad. It has no outlet to the sea and contains large areas of desert or semi-arid savanna. The drainage basin is roughly coterminous with the sedimentary basin of the same name, but extends further to the northeast and east. The basin spans eight countries, including most of Chad and a large part of Niger. The region has an ethnically diverse population of about 30 million people as of 2011, growing rapidly.
