Throughout the 20th century, Peru endured armed territorial disputes, coups, social unrest, and internal conflicts, as well as periods of stability and economic upswing. Alberto Fujimori was elected to the presidency in 1990; his government was credited with economically stabilizing Peru and successfully ending the Shining Path insurgency, though he was widely accused of human rights violations and suppression of political dissent. Fujimori left the presidency in 2000 and was charged with human rights violations and imprisoned. Even after the president's regime, Fujimori's followers, called "Fujimoristas", have caused political turmoil for any opposing faction in power. The last elected president Pedro Pablo Kuczynski resigned in March 2018 after a corruption scandal went public and to avoid impeachment by a congress dominated by Fujimoristas.
