Although much reduced, trans-Saharan trade continued. But trade routes to the West African coast became increasingly easy, particularly after the French invasion of the Sahel in the 1890s and subsequent construction of railways to the interior. A railway line from Dakar to Algiers via the Niger bend was planned but never constructed. With the independence of nations in the region in the 1960s, the north–south routes were severed by national boundaries. National governments were hostile to Tuareg nationalism and so made few efforts to maintain or support trans-Saharan trade, and the Tuareg Rebellion of the 1990s and Algerian Civil War further disrupted routes, with many roads closed.
