By the way how come Pyramids don't exist to the scale that they made before? Our president/King of England/King Solomon/Before Plato Athens couldn't pull that off. Yet some guy(King or leader) is chopping heads off(sacrificing or something) in the Central America/Egypt or where ever is accomplishing it without this outside help? The word Rebel seems to fit somewhere.
The largest pyramids were built in Dynasty 4, early in the Old Kingdom. After Dynasty 4, the state was weakening and the power of central authority was slipping. The kings in the later Old Kingdom could not marshall the resources and manpower that the earlier kings did, and when the Old Kingdom collapsed around 2200 BCE, Egypt descended into civil war.
The last lengthy spurt of pyramid building was in the Middle Kingdom, beginning c. 2066 BCE. By that point the religion of the state was changing and it appears huge pyramids were no longer the emphasis. The emphasis became some degree of standardization in royal tombs. The pyramids of this time were roughly the same size and followed a similar layout as to temples and other ancillary structures. At this point it's not that the kings were weaker, because most of the kings of Dynasty 12 (e.g., Senusret III) were much more powerful than those of Dynasty 4. It's just that the emphasis in royal funerary monuments was different.
It's also important to understand that an ancient Egyptian king was nothing like a modern king, president, or other head of state. The ancient king was imbued with absolute, unquestionable power. His word was law. Huge monuments in ancient times were not only dramatic religious statements but also a direct reflection of the ideology and power of the state—meaning the king. And that's what pyramids were in socio-political terms.
The difference is, the king could call you up to build monuments, and you had no say in the matter. It's a system we call corvée labor and was similar to a military draft. In fact, at any time, an Egyptian king in the Old Kingdom could call up citizens to serve in military campaigns or to build monuments. The governors who controlled the various nomes or provinces of ancient Egypt were then responsible for drawing up the necessary manpower from their territories. Some of these ancient officials left autobiographies in their tombs extolling their successes in rounding up sufficient manpower whenever the king asked for it.
The important thing is, you had no say in the matter. Again, akin to a military draft, if you were called up but fled to avoid the labor, you'd be considered basically the same as a military deserter. In ancient Egyptian terms, the state could then arrest your family and sell them into slavery, and if you were caught, you most likely faced death. So for most people it wouldn't have been worth the risk to do this. Most people would've done their duty and participated in corvée labor. The work would've been very hard and dangerous, but the laborers were well paid and received all of the support, medical care, and equipment they needed (at the expense of the state). And they would've worked for the state for only several months, after which they would've been sent home to return to their farms. In the Old Kingdom the population of the Nile Valley was at least 800,000 people and possibly as high as a million, so the state had all of the manpower it needed to keep the work going year round.
