He is well remembered for having signed with the minister plenipotentiary of Colombia, Fabio Lozano Torrijos, the controversial Salomón-Lozano Treaty, which resolved the Colombian–Peruvian territorial dispute (March 24, 1922).

[citation needed] While he was pursuing his university studies, he began publishing poetry in the magazine Letras de Tacna (1896) and in the biweekly La Neblina, directed by José Santos Chocano (1896-1897).

When the coup d'état of February 4, 1914 against Guillermo Billinghurst took place, he ardently defended the right to presidential succession of the first vice president Roberto Leguía (Augusto's brother).

In one of them, on March 21 of that same year, there were clashes and street shootings, resulting in Alberto Salomón himself being injured, who had himself carried on a stretcher to the parliamentary premises, struggling to enter.

[citation needed] His best known position was that of Minister of Foreign Affairs (from October 1, 1920, to February 27, 1924), a role he assumed after the resignation of Chancellor Melitón Porras Osores [es].

[citation needed] In his first period as chancellor, he signed with the English representative in Lima, Mr. A. C. Grant Duff, the arbitration protocol for the question of La Brea and Pariñas (May 27, 1921), complying with law No.

[11][12] By the time the treaty was formally approved by Peru and Colombia, Salomón had already been definitively separated from the command of the chancellery and shortly before, from 1925 to 1927, he had served as legal advisor to the Peruvian delegation that took care of the preparations in Arica for the regional plebiscite, which did not take place.
