Whatever initial misgivings Louis Philippe's government may have had about occupying Algeria, the geopolitical realities of the situation created by the 1830 intervention argued strongly for reinforcing French presence there. France had reason for concern that Britain, which was pledged to maintain the territorial integrity of the Ottoman Empire, would move to fill the vacuum left by a French withdrawal. The French devised elaborate plans for settling the hinterland left by Ottoman provincial authorities in 1830, but their efforts at state-building were unsuccessful on account of lengthy armed resistance.
