How was indonesia’s democracy affected when suharto gained power?

It's debatable. He was the president for over 30 years and was famous for his anti-communist purges. His rule was militaristic and the country went through periods of major turbulence having some financial crises, but also periods of great growth and economic and political stability. That's why many people still love him while many despise him, even claiming that he embezzled billions of dollars.
