Greek and Roman
The first Olympics occurred in 776 BCE and included only four sports: footrace, wrestling, long jumping, and javelin. Nowadays, there are summer and winter Olympics and fifty-six sports in all. Some of these include archery, diving, table tennis, synchronized swimming, and weight lifting.
In Ancient Rome, aqueducts were elevated water systems, their structure canal-like. The water, from springs, wells, and distant lakes, was used to supply for their bathhouses, fountains, and private household. They are used this day in the form of a toilet, something incredibly important for daily life.
In Rome, women were given the rights to own property and businesses. Extremely rare for its time, it paved the way for women around the world. In present times, women can go to school, get degrees, be the head of households, be a part of office, and an infinite number of other things.
