Editing Rodrigo Duterte (section)

===Education and early political career===
Duterte studied political science at the Lyceum of the Philippines University, graduating in 1968, before obtaining a law degree from San Beda College of Law in 1972. He then worked as a lawyer and was a prosecutor for Davao City, before becoming vice mayor and, subsequently, mayor of the city in the wake of the Philippine Revolution of 1986. Duterte was among the longest-serving mayors in the Philippines, serving seven terms for a span of more than 22 years in office.

Frequently described as a populist and a nationalist, Duterte's political success has been aided by his vocal support for the extrajudicial killing of drug users and other criminals. Human rights groups have documented over 1,400 killings allegedly by death squads operating in Davao between 1998 and May 2016; the victims were mainly drug users, petty criminals and street children. A 2009 report by the Philippine Commission on Human Rights confirmed the "systematic practice of extrajudicial killings" by the Davao Death Squad.
