This was because of the Nile's yearly floods.
Explanation:
The development of the civilization of Ancient Egypt was only made possible by the flooding of the Nile. This great river was the only source of water that fertilized Egypt's otherwise desert land. A great monsoon brought rain which resulted in Nile's inundations. It was the most important yearly event back then and even represented the reference for the three seasons of Ancient Egypt: <em>inundations, growth </em>and<em> harvest.</em>
The floods occurred each year and the Egyptians still celebrate it as a national holiday starting in mid-august and lasting <em>two</em> <em>weeks</em>.
Rock and roll influenced daily life, fashion, attitudes and language in a way few other social developments have equalled. As the original generations of rock and roll fans matured, the music became an accepted and deeply interwoven thread in popular culture. Beginning in the early 1950s, rock songs and acts began to be used in a few television commercials; within a decade this practice became widespread, and rock music also featured in film and television program soundtracks.
