The gathering at Amritsar (1919), the rallies in Soweto (1976) and the demonstrations in Tianamen Square (1989) directly resulted in (4) violence against the protesters. The Amritsar Massacre was when groups of nonviolent protesters gathered in the Jallianwala Bagh Garden and were fired upon by troops from the British Indian Army. The Soweto Uprising was a series of protests led by high school students who did not want to have the Afrikaans medium of instruction instilled in their schools, but this was met with huge violence and an extremely high number of casualties. The Tiananmen Square protests was when Chinese students protested because of China's corrupt political system and many protesters and civilians were killed.
It was a imperial examination in Song Dynasty (later on), but in Han Confucianism was hella on, so u need dat knowledge to be in gov. A lot of goverment after Qin Dynasty (previous dynasty) was adopted. So the Emperor had all the power, and all the "jobs" cam down on familly line. So pretty much be wealthy, know confucianism, and have a father who was in the gov, or if the emporer chose u, and u must have a d!(k. Okey, just googled in wiki to be sure and it's says "the states made by the emperor were assigned to official dedication..." So I guess emperor chose the gov, but all of them had to be educated. Sooo if that helps, hard question though.
