Duchy of Milan throughout the early modern period. In the mid-18th century, census records listed 715 inhabitants. During the turbulent
Napoleonic era and the subsequent Austrian restoration, Rebbio underwent several administrative changes while maintaining its status as a commune. Under the
Cisalpine Republic, it was initially assigned to the of Olgiate in 1797, then moved to District I of Como in 1798. This arrangement continued under the subsequent
Italian Republic (1802) and the
Napoleonic Kingdom of Italy (1805), where it belonged to Canton IV within District I of Como, part of the Department of Lario. The population around this time was approximately 700. A Napoleonic decree in 1809 temporarily aggregated the neighbouring commune of into Rebbio, but this union was reversed with the establishment of the Austrian
Kingdom of Lombardy–Venetia in 1815–1816. Under Austrian administration, Rebbio was confirmed as an autonomous commune within District I (later District VIII) of the
Province of Como, with a population recorded as 1,081 in 1853. Following the
Second Italian War of Independence and the annexation of Lombardy to the
Kingdom of Sardinia in 1859 (which became the
Kingdom of Italy in 1861), Rebbio was included in I of Como, within I of Como, in the province of Como. The population continued to grow, reaching 1,440 at the 1861 census, 1,881 in 1901, and 2,538 in 1921. Rebbio's long history as an independent municipality ended in 1927. By Royal Decree No. 1497 of 4 August 1927, the communes of Rebbio, Breccia, and Camerlata were officially suppressed and aggregated into the municipality of Como, effective from 17 September 1927. Since then, Rebbio has functioned as an urban district or within the city administration. ==Geography==
