The origin of millet is diverse with varieties coming from
both Africa and Asia.
Pearl Millet (Pennisetum glaucum) for example comes from Tropical
West Africa and Finger Millet (Eleusine coracana) from Uganda
or neighboring areas. From African highlands, E.coracana was
taken to India about 3000 years ago, and Europe at the beginning
of the Christian era. Later, the crop was widely distributed
both in many African countries as well as in the Indian sub
continent.
From Eastern Asia there are varieties such as Froxtail Millet
(Setaria italica), Common Millet (Panicum miliaceum), Little
Millet (Panicum sumatrense) Barnyard Millet (Echinochloa crus-galli)
and Kodo Millet (Paspalum scrobiculatum).
The oldest historical roots of millet are to be found in China
4500 BCE, where it was considered a sacred crop. One of the
earliest recorded writings dates from 2800 BCE giving directions
for the growing and storing of the grain.
During prehistoric times, people of Northern India were also
cultivating millet. Millet's travel continued throughout the
Middle East and Northern Africa where it became a staple. It
further became typical food of the Sumerian diet about 2500
BCE.
Millet was even mentioned in the Hebrew bible. The idyllic
Hanging Gardens of Babylon were said to have included millet
among their treasured plants. Through trading with Eritrea and
Somalia circa 3000 BCE, the early Egyptians learned from the
Africans how to cultivate millet, which would grow well in the
dry Sahara, where wheat and barley were unable to thrive.
There are about 6,000 varieties of millet throughout the world
with grains varying in color from pale yellow, to gray, white,
and red. 3/4/5/6
