It remains a conventionally “tercerista” Party, calling for a “third way” between capitalism and socialism – a way that would be more humane and truly democratic than either competing social-political system.

Founded by Remo Di Natale, Benjamín Miguel Harb, Javier Caballero, and Emanuel Andrade.

[4] In 1967, the party took part in the Government of the president of René Barrientos Ortuño, being given responsibility for the Ministry of Labour and Social Security and this was a major misjudgment by the PDC leadership.

The party's youth organization had been discontented with the third-road philosophy for some time, and the mine camp invasions helped to crystallize their rebellion; they favored revolutionary socialism as a solution to Bolivia's dilemmas.

Several discontented members of the party, including Jose Luis Roca Garcia, also left to join General Alfredo Ovando Candía's short-lived nationalist revolutionary government in 1969–1970.
