JOHANNESBURG (AP) — As 72-year-old Nonki Kunene walks through the corridors of Thabisang Primary School in Soweto, South Africa, she recalls the joy she and many others felt 30 years ago when they voted for the first time.

It was at this school on April 27, 1994, that Kunene joined millions of South Africans to brave long queues and take part in the country’s first democratic elections after decades of white minority rule which denied Black people the right to vote.

The country is gearing up for celebrations Saturday to mark 30 years of freedom and democracy. But much of the enthusiasm and optimism of that period has subsided as Africa’s most developed economy faces a myriad of challenges.

Like many things in South Africa, the school that Kunene remembers has changed, and what used to be a school hall has now been turned into several classrooms.
