The Llosas family has traditionally been active in the Catalan textile industry as cotton weavers; in the 19th century they established themselves in middle-low range of the local bourgeoisie.

[3] Paternal grandfather of Pedro, Juan Llosas Pujol, originated from Olot (Girona province), located in the comarca of Alta Garrotxa at the Pyrenean foothills.

[5] When the shop was inherited by his cousin, Albert Escubós Llosas, he returned to Olot and married Rosa Badía Trull (died 1896),[6] a native of El Sallent.

[16] Having returned to Olot in 1893 Llosas Badía married Anna Serat-Calvó y Plana (died 1942);[17] they settled at calle de San Jerónimo 47.

Painting activity of Escuela de Olot and literary works of Marian Vayreda y Vila made it cultural centre of regional Traditionalism and conservative Catalanism.

[55] In the provincial self-government he represented a Traditionalist version of regionalism, declaring himself a Catalanist and anti-centralist;[56] his opening address in the chamber was in Catalan, an extravaganza which earned him admonition by the president.

His parliamentarian activity – vibrant especially during earlier terms[70] - was marked mostly by defense of Catholic Church[71] and by his modest Catalanism,[72] culminating in confronting the government sponsored Ley del Candado.

[78] Llosas, unlike other key Carlist from the province Dalmacio Iglesias, tended to demonstrate more attraction for Catalanism than the official party executive would allow.

[79] Called in the wake of growing social tension, the congregation declared the Restoration political system defunct and assumed a potentially revolutionary shape, pursuing also a highly regionalist model of state.

The Carlists themselves were divided into 3 factions led by Junyent, Iglesias and Llosas, the latter turned against La Lliga running as an ultra-Right anti-regionalist hopeful.

Instead, he neared the right wing of disintegrating Conservatives, the Mauristas;[93] in the 1919 electoral campaign he unsuccessfully ran for the Senate as a governmental candidate,[94] defeated for the upper chamber also in 1921 with only 16% of the votes gathered;[95] some kept referring to him as "jaimista".

Little is known about his tenure; according to present-day scholar, he demonstrated rather heavy hand and acted along "lógica dins un sistema caciquista basat en la venjanca",[97] having been firm element of the caciquismo structure.

[118] Despite differences with the military, Llosas by no means could have been considered in opposition to Primo;[119] his stance during tenure in Diputación Provincial and Mancomunitat should rather be viewed as efforts to find a compromise within framework of the regime.

Press of the era provided only official information about cultural activities,[128] diplomatic routine,[129] construction of public utility establishments,[130] propaganda,[131] building new railway lines[132] etc., though there were single complaints about his uncompromising stand recorded.

[142] He basked in prestige of key Girona politician,[143] a charismatic figure[144] and local patricio, his house continuously visited by applicants seeking support.

[145] Llosas’ position changed dramatically upon advent of the Republic: as a former dictatorship tycoon, a monarchist and a Traditionalist reactionary he found himself politically sidetracked.

[147] Llosas focused on religious activity: in the early 1930s he took part in Catholic initiatives like Pro Ecclesia et Patria weeks, contributed to confessional periodicals[148] and in 1933 led a large group of Catalans visiting Vatican.

[150] During run-up to the 1933 electoral campaign he was initially reported as standing in candidatura de derecha agraría, neighboring with frontline Carlist activists like Urraca Pastor and defined as "tradicionalista";[151] eventually he declared the news not authorized.

[153] In early 1936 Llosas together with other Catalan Carlists[154] took part in broad monarchist gatherings led by Calvo Sotelo,[155] though his relations with Carlism remained loose.

[157] Following the outbreak of hostilities Olot was overtaken by Republican militias, who raided estates belonging to individuals deemed sympathetic towards the Right; according to one version the Llosas’ Mas Quintana mansion in Santa Pau was ransacked, with all movable items robbed and the immovable ones[158] destroyed;[159] according to another, it was expropriated in an orderly manner.

Immediately following Nationalist seizure of Catalonia, in February 1939 Llosas rushed to offer his services to the new Presidente de la Diputación,[162] March 1939 entrusted with gathering trade and industry managers of Girona province to proceed with the post-war reconstruction.
