Upon his assumption to office, Melgarejo charged all ministerial portfolios to Mariano Donato Muñoz as secretary general pending the formation of a proper ministerial cabinet.[6] A full council of ministers was appointed on 19 June 1867, two and a half years later, composed of four ministers. In addition to the four ministries, Muñoz was appointed to the position of head of the cabinet, a position tantamount to a prime minister, with the power to preside over the cabinet in the event of the absence of the president.[4] On 16 February 1869, a new office, dubbed as the Ministry of Industry and Worship, was established.[15]
