Solomon succeeded his father David in 1015 BC at 20 years of age, to reign for 40 years.
Israel at that time extended from the Euphrates and the Red Sea to the Mediterranean, with Jerusalem its capital.
In Solomon's era none of the wars between Egypt and the River Kingdoms involved Palestine. Art and science flourished, commerce was extensive and profitable.
Trade extended to Spain and India, with Hiram's navy to protect the trade.
Israel was indeed prosperous.
