AoA's answers.
"1) Cambyses II
Persian king, son of Cyrus the Great, completed conquest of Eygpt circa 525 BC"
Correct.
"2) Chandragupta
Created first real Indian empire, defeated forces left by Alexander the Great in India"
Correct. I am surprised ppl actually know about him ....
"3) Li Shimin
Son of first Tang Emperor"
Correct. Actually it was believed he's the one who pushed his father to fight it out with other contenders for the imperial throne (it was after the Sui had fallen apart). He would help his father conquer the empire during the rise of the Tang.
Later, Li Shimin would fall out with his brothers and then got them killed. And forced his father off the throne and assumed power himself as the emperor Tang Taizong. Despite this, IMHO, I believe he was one of the greatest emperors China ever had.
He pushed Tang power all the way to the Hindu Kush (there're princes in India swearing allegiance to him). the archetype warrior-king with a more than a fair share of scholarly flair. Left a great empire for the Tang to inherit.
"4) Wang Mang
Founded a dynasty in western Han, circa 9 AD, but it didn't last long"
Yep. It's the Hsin (Xin) dynasty and cut the Han dynastic period into two. The Communist believed he was the first communist cos of his socialist policies. Basically Wang Mang believed the power of the state would come fr the well-being of the peasants. Unfortunately he and his policies were too advanced for his time (loans to peasants, state granaries etc), so he couldn't make much headway .... Some of his ideas who would be adopted as common practise later on.
"5) Toghrul Khan
Leader of the Keraits, a mongol tribe, and early supporter of Ghengis Khan"
Correct too, he's the adopted 'father' of Genghis Khan. Support GK in his early rise (to help himself as well), later found him too strong and tried to destroy him. Got destroyed instead. You know nomadic politics.
"6) Abu Bakar
Don't know this guy, sounds Indian"
Arab.
"8) Menes
Founder of first dynasty of Eygpt"
Yep.
"9) Imhotep
Architect to 3rd Dynasty Pharoah Djoser, designed step Pyramid"
Yep.
"10) Harsha
Indian King Harsha was the ruler of a northern India empire that
reached from Magadha to Kashmir"
He was the ruler of the last native Indian empire. After his time, it would be the foreign Islamic Delhi Sultanate and the Moghuls and then the British who would rule a major part of India.
I know it's a common Muslim name but why's it a favourite in the first place? Do you know, per chance?
At least not right up to your face.
