I also just asked this in /r/askhistory but this sub seems a lot more populated.

I'm writing a historical fiction novel that takes place in the years before and at the start of the reign of Shulgi, son of Ur-Nammu. I am trying to go by Middle Chronology, and using good old Wikipedia I can place the beginning of the dynasty at 2112 BCE (2047 short). 17 years later, in 2094 BCE (2030 short) Ur-Nammu dies suddenly in battle with the ousted Gutians and his son Shulgi takes over. I'm having difficulty doing the math here, as it seems like either Shulgi was an infant when his 48-year reign began, or he was possibly 17, or something else entirely. My question is, how old was Shulgi when his father died?

Bonus questions: Is there information on how long it took for Shulgi to come to power, whether it was immediate or took perhaps up to a year (poems indicate social chaos followed Ur-Nammu's death)? Perhaps if there was any sort of contemporary political intrigue that could be drawn upon for dramatic effect?

Do they not see that their children are genetically (I think) inferior? They can't have that much pride can they?

I have been trying to find good books about arab slave trade, and by good books I mean from professors in universities. Could anyone recommend me one?

I've seen a lot of different numbers for fuel costs per pound but most are recent costs. Rumor was that Alan Shepard had a six iron head attached to some kind of rock mining shaft, but for simplicities sake and to not have to deduct unknown shaft weights, what would be the fuel cost to smuggle an average 1971 six iron and 2 golf balls into space?

Or with the discovery of the new world came supremacy based on race?

The only thing i can think of is between local tribes.

After reading a bit on Marco Polo, I began to wonder if the opposite was true; if there was any account by an Asian trader or scholar of their travels through the West.

My interest is mostly on China, but my curiosity extends to all of Asia, and even the Middle East (if anyone is willing to answer).

How was this information received by the respective country?

I learned recently about Indira Gandhi's efforts to stem the tide of overpopulation through forced sterilization. I've been wondering how she could've gone about to forced sterilization of so many men.

For example, take an English speaking peasant living in the Kingdom of England and a Norman speaking peasant living in the King of England's French holdings. To what extent would they see each other as different if they do at all?

Specifically, how did a captain make sure that his crew knew what he wanted them to do?

I read in a book that casualty rates amongst armored knights were often quite low. In part, this was due to their being better protected, but they were also more likely to be spared because they could be ransomed back to their family for gold, or used in negotiation (IE prisoner exchange).

What I have trouble imagining, however, is how someone would go about restraining a foe during battle. It is my understanding that Kings often traveled with a personal retinue which accompanied them in battle. Did knights have a similar retinue to restrain their prisoners, or was there some kind of etiquette to surrender?

I assume that the concept of a year is fairly innate to watching the skies for millennia (and similarly so with months). I also know that other countries have understandably unique, non-Abrahamic dates for year we are in (such as Thailand and China), while the Western year is concurrently noted for many reasons. But how did the whole Sunday-Saturday thing come about? Is this a relatively modern construction, and do any prominent cultures that exist today follow a different sequence of days? While the cycle of the moon may vary, dividing anything by seven seems to be an odd choice to my ignorant brain.

I know that the representative for China before was the ROC/ Taiwan but what made the UN favor PRC over ROC/ Taiwan?
