The Battle of Brașov (German: Schlacht bei Kronstadt; Hungarian: Brassói csata) was fought on July 17, 1603, between the troops of Wallachia led by Radu Șerban and the Habsburg monarchy on one side and the Transylvanian troops led by Mózes Székely on the other side. Mózes Székely was killed on the battlefield, and the Wallachian lord Radu Șerban became ruler of Transylvania until September 1603, when Giorgio Basta and the imperial commissioners took control of the country in the name of the emperor.
