Blah was born in Toweh Town, Liberia, a Gio-speaking hamlet in north-eastern Nimba County, close to the border with the Ivory Coast. He joined with Taylor because of a shared hatred of President Samuel Doe, who had killed Blah's wife along with hundreds of others in an ethnic-related massacre. He trained with Taylor in a Libyanguerrilla camp and served with him as a general during Liberia's civil war in the 1990s. He held the post of ambassador to Libya and Tunisia after Taylor was elected in 1997. In July 2000 Blah was appointed as Vice President after the death of Enoch Dogolea who was rumoured to have been poisoned.
Blah was known as a quiet and unassuming man, driving his own jeep around town rather than using a motorcade and driver, and wearing flowing African robes instead of the normal olive green military uniform. He was constantly annoyed by the presence of bodyguards following him around.
In June 2003, Taylor had left the country for peace talks in Ghana, and while there he was indicted by the war crimes tribunal in Sierra Leone. Blah was urged by the United States to take power from Taylor during his absence, but Blah made no such attempt. After Taylor's return, Blah was held under house arrest for ten days, but was subsequently absolved and reinstated as vice president.
When Taylor resigned in August of that year, Blah briefly succeeded him as president. He was condemned by Liberian rebel groups for his close ties to Taylor; they charged that he would simply continue Taylor's practices. Blah responded by calling the rebels "brothers" and saying "Let bygones be bygones. If there is power, we can share it." He invited the rebels to negotiate in his own house.
On 7 April 2008, Blah said that he had been sent a subpoena to testify at Taylor's trial before the Special Court for Sierra Leone in The Hague. He said that he would testify and "speak the truth",[1] and he testified on 14 May 2008, describing child soldiers and the relationship between Taylor and Foday Sankoh.[2] On 1 February 2009, Blah was accused of taking part in the murder of RUF commander Sam Bockarie, by a witness narrative to the commissioners of Liberia’s Truth and Reconciliation Commission (TRC).
The witness, a senior commander of the defunct Anti-Terrorist Unit (ATU) of exiled president Charles Taylor, claimed Vice President Blah was part of the conspiracy and participated in the killing of Bockarie in the town of Tiaplay in Nimba County.[citation needed]
