Boulevard Mortier

The French war department had completed the Thiers wall – including fortifications, a dry moat, a Rue Militaire and a large berm – around 1840. In 1859, the military engineering service gave conditional control to the Paris city council.^[2] The expansion of the land area of Paris in 1860, by annexing bordering communities, created a situation where everything within the Thiers wall was Paris and everything without was not. The Thiers wall, with its accompanying berm and moat, led to a profound disruption and complication of the synergistic relationship between Paris and its suburbs. Paris city council started upgrading and conversion of some sections of the Rue Militaire into boulevards in 1861, with the (yet unnamed) Boulevard de Mortier one of the first stretches to open.

In 1864, the boulevard was named after Édouard Mortier (1768–1835), Duke of Trévise and Marshal of France.^[1]

Each section of the upgraded Rue Militaire was then named for a marshal of the First French Empire (1804–1814) who served under Napoleon I, leading to the entire ring being collectively called the Boulevards of the Marshals.^[1] The Boulevards of the Marshals concept was almost fully realized by 1932, though the final three sections, closing the ring, would not be completed until 2005. Of the 22 boulevards, 19 have been named for Mortier or one of his fellow First Empire marshals.
