Angered by this step, Ras Alula took prisoners the members of an Italian exploring party commanded by Count Salimbeni, and held them as hostages for the evacuation of Wa.
Designed by Bernardo Rossellino, and now the Banca d'Italia; the enormous block of the Monte de' Paschi, a bank of considerable wealth and antiquity, enlarged and partly rebuilt in the original style between 1877 and 1881, the old Dogana and Salimbeni palaces; the Palazzo Spannochi, a fine early Renaissance building by Giuliano da Maiano (now the post office); the Loggia di Mercanzia (15th century), now a club, imitating the Loggia dei Lanzi at Florence, with sculptures of the 15th century; the Loggia del Papa, erected by Pius II.; and other fine buildings.
Exasperated by the tyranny of the Salimbeni and other patrician families allied to the Ghibellines, it decreed in 127 7 the exclusion of all nobles from the supreme magistracy (consisting since 1270 of thirty-six instead of twenty-four members), and insisted that this council should be formed solely of Guelf traders and men of the middle class.
The twelve who replaced the council of nine (as these had previously replaced the council of the nobles) consisted - both as individuals and as a party - of ignorant, incapable, turbulent men, who could neither rule the state with firmness nor confer prosperity on the republic. They speedily broke with the nobles, for whose manoeuvres they had at first been useful tools, and then split into two factions, one siding with the Tolomei, the other, the more restless and violent, with the Salimbeni and the noveschi (partisans of the nine), who, having still some influence in the city, probably fomented these dissensions, and, as we shall see later on, skilfully availed themselves of every chance likely to restore them to power.
This government lasted only twenty-two days, from the 2nd to the 24th September, and was easily overturned by the dominant faction of the dodicini (partisans of the twelve), aided by the Salimbeni and the populace, and favoured by the emperor Charles IV.
The turbulent action of the twelve and the Salimbeni, being dissatisfied with these changes, speedily rose against the new government.
But the Sienese people, being called to arms by the council of fifteen, made a most determined resistance, routed the imperial troops, captured the standard, and confined the emperor in the Salimbeni palace.
In that year the first plot against the Viscontian rule, hatched by the twelve and the Salimbeni and fomented by the Florentines, was violently repressed, and caused the twelve to be again driven from office; but in the following year a special balia, created in consequence of that riot, annulled the ducal suzerainty and restored the liberties of Siena.
Another family quarrel, that of the Salimbeni at Rocca D'Orcia, was ended by her intervention in 1377.
