Ukrainian defensive line was a Russian heavily fortified defensive line on the territory of modern Ukraine built between 1731–1764 on the lands of the Zaporozhian Sich and the Cossack Hetmanate. Built by imperial Russia, it strengthened the defense of the southern borders from Tatar incursions and established military bases in approximation to the Crimea. 285 kilometers in length, it comprised 16 newly-constructed forts and 4 old forts repaired. The first stage was built from 1731–40 and subsequent construction began in the 1740s.
