Petrova Niva

Petrova Niva (Bulgarian: Петрова нива, "Peter's field") is a historic area in the Strandzha mountains of southeastern Bulgaria where, between 11 and 13 July 1903, a group of Bulgarian Internal Macedonian-Adrianople Revolutionary Organization (IMARO) delegates announced the outbreak of an anti-Ottoman uprising aimed at liberating southern Thrace from Ottoman rule and proclaimed the Strandzha Republic.

[1] The area lies on the land of the village of Stoilovo in Malko Tarnovo municipality, Burgas Province, within the territory of Strandzha Nature Park.

It is among the 100 Tourist Sites of Bulgaria; a monument to the event was built in the 1950s and a church dedicated to Saint Petka was constructed in 2003 for the congress' centennial anniversary, as well as a museum.

Most of the delegates came from the region of Malko Tarnovo, though the areas of Edirne and Western Thrace were also represented.

Despite the lack of enough armaments and the varying preparedness of the local committees, the delegates agreed to aid the insurgents in Macedonia.
