president -allendae and ruled.He gave a referendum to the people of Chile,
to say yes or no to his rule.
#Pinochet thought that he would definitely win,but the people of chile said NO to his rule so he was not able to rule the country forever.
#So,after that the people of Chile got freedom from his rule and became
democratic.then in 2006 election Michelle Bachlet won and became president.
