The True Whig Party (TWP), also known as the Liberian Whig Party (LWP), is the oldest political party in Liberia and one of the oldest parties in Africa. Founded in 1869 by primarily darker-skinned Americo-Liberians in rural areas, its historic rival was the Republican Party. Following the decline of the latter, it dominated Liberian politics from 1878 until 1980. The nation was virtually governed as a one-party state under the TWP, although opposition parties were never outlawed.
