How Teodoro Obiang Became Africa's Longest-Ruling Leader

Teodoro Obiang Nguema Mbasogo took power in Equatorial Guinea on August 3, 1979, when he led a military coup against his own uncle, President Francisco Macías Nguema. Obiang had risen through the ranks of his uncle’s government, at one point overseeing the notorious Black Beach prison where political opponents were held and tortured. By the late 1970s, according to accounts from people close to the regime, Macías’s erratic, murderous behavior, including killings within his own inner circle, had convinced Obiang and other officers that removing him was necessary for their own survival. After roughly two weeks of fighting between loyalist and rebel forces, Macías was captured fleeing toward Cameroon, tried by a military tribunal, and executed by firing squad on September 29, 1979. Obiang, who had commanded the coup, assumed leadership first as head of a Supreme Military Council and later as president.

In his early years in office, Obiang presented himself as a reformer. He released political prisoners held under his uncle, promised a new constitution, and allowed some exiles to return. That opening proved limited. Equatorial Guinea remained a one-party dominated state in practice, and the elections held under Obiang from the late 1980s onward, in 1989, 1996, 2002, and beyond, were widely documented by international observers as fraudulent, with official results at times exceeding 97 to 99 percent of the vote in his favor.

The discovery of substantial offshore oil reserves in the mid-1990s transformed Equatorial Guinea’s economy and Obiang’s grip on power. Petroleum revenue turned the small country into one of the highest per-capita GDP nations in Africa on paper, while the majority of its population continued to live in poverty with limited access to basic services. A 2004 investigation by the US Senate’s Permanent Subcommittee on Investigations found that Washington-based Riggs Bank had handled hundreds of millions of dollars connected to Equatorial Guinea’s oil revenue, including tens of millions of dollars that investigators concluded had been diverted directly into accounts controlled by Obiang and his associates. Subsequent investigations in the United States, France, and Spain targeted assets held by Obiang’s son and designated successor, Teodoro Nguema Obiang Mangue, including a Malibu mansion, a private jet, and a fleet of luxury cars, all linked to allegations of embezzlement and money laundering.

Obiang has remained in office ever since, making him one of the longest continuously serving heads of state in the world, behind only a small handful of other rulers. His government has consistently ranked among the most repressive and least transparent in international human rights and corruption indexes, even as it has maintained diplomatic and commercial relationships with major Western governments and oil companies that depend on Equatorial Guinea’s petroleum exports.
