The party contested the 1997 general election, with the NPFL's leader, Charles Taylor, serving as the party's presidential candidate. Taylor won the presidential election with 75% of the vote. The party also won 49 of 64 seats in the House of Representatives and 21 of 26 in the Senate. Due to domestic and international pressure as a result of the Second Liberian Civil War, Taylor stepped down as president in August 2003. In October of that year, Taylor's successor, Moses Blah, and the members of the Legislature resigned and ceded power to the National Transitional Government of Liberia.
The party later contested the 2005 general election. The party's presidential candidate was Roland Massaquoi, who earned 4.1% of the vote. The NPP also won four seats in the House of Representatives and another four in the Senate.
