When did governmental authority begin in Jericho?
Early Jericho.
"Jericho started as a popular camping ground for the hunter-gathers of the Natufian culture dating to 10000 BCE.
"It wasn’t until the cold and drought caused by the last
Ice Age, or Younger Dryas, came to an end around 9600 BCE that year-round habitation and permanent settlements began in the area.
"Tell es-Sultan (Sultan’s Hill), 2 kilometers (1.2 miles) north of modern-day Jericho, became the earliest permanent settlement.
"It was a Pre-
Pottery Neolithic (New
Stone Age) settlement. It is situated on the Ein as-Sultan spring (later called Elisha’s Spring) supplying it with water.
"By about 9400 BCE the settlement grew to include more than 70 homes. These circular dwellings measured 5 meters (16 feet) in diameter and were built with clay and straw."
