Tomás Monje assumed office as the interim 41st President of Bolivia on 17 August 1946, and his mandate ended on 10 March 1947.

Having been ill at the time, Monje only assumed the position 27 days later, chairing the junta until new elections could be held.

They were dismissed when Monje formed his own cabinet on 26 August, with the exception of Secretary-General Roberto Bilbao la Vieja, Foreign Minister Aniceto Solares, and Minister of Work and Social Security Aurelio Alcoba who remained in their positions for the duration of Monje's mandate.

[1] The newly appointed members were Julio César Canelas (Defense), Eduardo Saenz García (Economy), Carlos Muñoz Roldán (Public Works), Manuel Elías P. (Education), and José Saavedra Suárez (Agriculture).

The civil junta and Monje's mandate ended on 10 March 1947 upon the inauguration of Enrique Hertzog, the winner of the 1947 general elections.
