The party was established in 1887 by Antonio Taboada to represent the interests of landowners and middle class merchants. The party advocated for mass suffrage. The
Colorado Party was established in the same year and was dominant until the
Liberal Revolution in 1904, and by the end of the 1947 revolution the Colorado Party was the only one left in the country. The Liberal Party continued to exist abroad and in 1963 the Renewal Group faction returned to the country to become the "official" opposition to the
Stroessner regime. In the
Constitutional Assembly elections in 1967 the party won just eight of the 120 seats, finishing third behind the Colorado Party and the Radical Liberal Party. After this defeat the party was reduced to being the third party in the Stroessner regime. They won only three Chamber seats in the
1968 elections. It regained a seat in the
1973 elections, and remained at four seats after the
1978 elections. The
1983 elections saw the party win seven seats, which they retained in the
1988 elections. After the Stroessner regime was overthrown, support for the party rapidly dwindled. In the
1989 elections the party received just 0.5% of the national vote and failed to win a seat. They failed to regain any seats in the
1993 elections, and did not contest any further elections. == Electoral history ==
