Just a note on your use of "mid-evil": the correct term is medieval. That word is derived from the Latin words for 'middle' and 'age'. So medieval means 'Middle Ages' - a rather unfortunate term referring to the time period between the Western Roman Empire (~5th century) and the Renaissance (~15th century). There's nothing inherently evil about the medieval period :)

Not really, but advanced is always a tricky word. Ancient Egyptian history essentially begins with the unification of the Upper and Lower Egyptian Kingdoms into a single state by Narmer. Before Narmer there is what is known as pre-Dynastic Egypt, which may be a bit misleading, there were dynasties, but there was no central Egyptian dynasty. Egypt was split into several communities called nomes. Nomes were centered around a single city most of the time, the less powerful nomes were swallowed by those that did. These nomes were formed after the beginnings of the agricultural revolution, and the Nile floods provided excellent soil for farmers. So these farming communities came together, and then organization arose, under the rule of a king-figure called a nomarch. There are bits and pieces of this time still exist, there's no written language we can gather very much from, and so it relies on archeologists and speculators to piece together pre-historic Egypt. In our sense of advancement, no. A central government made Egypt more defensible to invaders, trade and agriculture became more organized and rule of the country would become documented as well. In feats of architecture this organization and coordination between architects, workers, and commissioners allowed them to construct impressive palaces and of course, the more popular pyramids.
