Province of Reggio Emilia

The province of Reggio Emilia (Italian: provincia di Reggio nell'Emilia; Emilian: pruvînsa ed Rèz) is a province in the region of Emilia-Romagna in Italy. The capital city is the eponymous Reggio Emilia. It has a population of 532,157 in an area of around 2,292 square kilometres (885 mi) across its 42 municipalities.

The province is home to the historical Canossa Castle, property of the countess Matilde; it is where the Walk to Canossa of Henry IV occurred. Representatives of the free municipalities of Reggio, Modena, Bologna and Ferrara met in Reggio Emilia's Sala del Tricolore in 1797 to proclaim the Repubblica Cispadana, adopting the three colour green-white-red flag to represent their newly formed Republic; it was later adopted in 1848 as the national flag.
