At the height of demographic expansion around 1325, the urban population may have been as great as 120,000, and the rural population around the city was probably close to 300,000. The Black Death of 1348 reduced it by over half, about 25,000 are said to have been supported by the city's wool industry: in 1345 Florence was the scene of an attempted strike by wool combers ("ciompi"), who in 1378 rose up in a brief revolt against oligarchic rule in the Revolt of the Ciompi. After their suppression, Florence came under the sway (1382–1434) of the Albizzi family, who became bitter rivals of the Medici.
