Festus Mogae, former president of Botswana who led the diamond-rich nation through its HIV/AIDS crisis, has died at 86. During his decade in office, he confronted an epidemic that had infected nearly 40 percent of the country's adult population, declaring citizens were "threatened with extinction" by the disease. His economic background helped shape Botswana's response to both health and financial challenges.

Mogae embraced the U.S. PEPFAR program, making Botswana the first African nation to provide free antiretroviral treatment to its citizens. This partnership transformed the country's approach to HIV, with nearly all positive individuals receiving lifesaving treatment by 2021. The program, started under President George W. Bush, has faced funding cuts under current U.S. administration.

Beyond healthcare, Mogae oversaw substantial economic growth through Botswana's diamond industry. He left office in 2008 after a constitutional amendment limited presidential terms to 10 years. In 2008, he received the Ibrahim Prize for African leadership, recognizing his governance and respect for democratic norms. Mogae's legacy includes both successful economic management and pioneering public health initiatives.
