[3] The Humanist Party was registered before the Supreme Electoral Tribunal on January 17, 2017.

Its general secretary is Rudio Lecsan Mérida, former director of the National Civil Police during the government of Alfonso Portillo, and a former leader of the Humanist Party was the Guatemalan diplomat and politician Edmond Mulet.

The party supports the withdrawal of Guatemala from the Central American Parliament.

In January 2020, the Humanist Party declared itself "in opposition" to the government of Alejandro Giammattei, but within a few months the party became part of the ruling coalition.

Mulet denounced the act and resigned his membership of the party.
