Five years after the Greeks gathered for their first Olympic Game in 776 BCE, the host of centuries-old city-sized feudal states in China received a new company, Qin, the future empire builder. Eighteen years after the investiture of Qin, tradition had it that Rome was founded on the hills beside the River Tiber. The legend’s veracity is much questioned, but it was around this time that the Greek and Phoenician colonizers brought the model of city-state to the western Mediterranean and founded Carthage, Rome’s future arch enemy.

Their priority is to raise, protect, and take care of their children meanwhile the father works to provide what is needed. Sometimes, corporations favored or pay more to women that are not mothers. Some studies have shown that women that are not mothers earn 5% to 6% more than mothers.
