Countess Sidonija Rubido Erdődy (1819–1884) was Croatia's first opera primadonna and an important member of the Illyrian movement.

Sidonija Rubido Erdődy was born on 2 February 1819 in a small castle on Razvor estate, near a place called St Peter, above the hilltop of Sveta gora (St Mount) with the Chapel of Our Lady of Jerusalem.

At that time there was no maternity hospital in Zagreb, but her name was enlisted in the registry of births within the Parish of St Mark.

[2] Sidonija Rubido responded to the ideals of the Illyrian movement with her youth, the centuries of her heritage, and her remarkable music education.

She was rehearsing a lot to perform the title role in opera Ljubav i zloba (Love and Malice) by Vatroslav Lisinski, which had the premiere on 28 March 1846.
