Hermandades--brotherhoods or associations for the maintenance of public peace and private rights--were no new thing. In the troubles of 1282, caused by the rebellion of Sancho IV against his father, the first idea of his supporters seems to have been the formation of such organizations.[75] In these associations, however, the police functions were subordinated to the political object of supporting the pretensions of Sancho IV and, recognizing their danger, he dissolved them as soon as he felt the throne assured to him. After his death, his widow the regent Doña María de Molina, organized them anew for the protection of her child, Fernando IV, and again in 1315, when she was a second time regent in the minority of her grandson, Alfonso XI.[76] The idea was a fruitful one and speedily came to be recognized as a potent instrumentality in the struggle with local disorder and violence. Perhaps the earliest Hermandad of a purely police character, similar to the later ones, was that entered into in 1302 between Toledo, Talavera and Villareal to repress the robberies and murders committed by the _Golfines_ in the district of Xara. Fernando IV not only confirmed the association but ordered the inhabitants to render it due assistance, and subsequent royal letters of the same purport were issued in 1303, 1309, 1312 and 1315.[77] In 1386 Juan I framed a general law providing for the organization and functions of Hermandades, but if any were formed under it at the time they have left no traces of their activity. In 1418 this law was adopted as the constitution of one which organized itself in Santiago, but this accomplished little and, in 1421, the guilds and confraternities of the city united in another for mutual support and succor.[78] There was, in fact, at this time, at least nominally, a general Hermandad, probably organized under the statute of Juan I and possessing written charters and privileges and customs and revenues, with full jurisdiction to try and condemn offenders. It commanded little respect, however, for it complained, in 1418, to Juan II of interference with its revenues and work, in response to which Juan vigorously prohibited all royal and local judges and officials from impeding the Hermandades in any manner. The continuity, nominal at least, of this with subsequent organizations is shown by the confirmation of this utterance by Juan II in 1423, by Ferdinand and Isabella in 1485, by Juana la Loca in 1512 and 1518, by Philip II in 1561, by Philip III in 1601 and by Philip IV in 1621.[79] In the increasing disorder of the times, however, it was impossible, at that period, to maintain the efficiency of the body. In 1443 an attempt was made to reconstruct it, but as soon as it endeavored to repress the lawless nobles and laid siege to Pedro López de Ayala in Salvatierra its forces were cut to pieces and dispersed by Pedro Fernández de Velasco.[80] Some twenty years later, in 1465, when the disorders under Henry IV were
