This thesis concludes that (1) Immediately following the July Revolution, the Paris government refused to concede the right of search to British commanders. (2) Due to France's isolation in 1831-1833, she sought British support by negotiating the conventions of 1831 and 1833. (3) In response to Palmerston's insistence and to preserve France's influence Sdbastiani signed the protocol of a five-power accord to suppress the slave trade. Guizot accepted the Quintuple Treaty to facilitate an Anglo-French rapprochement. (4) Opposition encouraged by the Webster-Ashburton Treaty, however, forced Guizot to repudiate this new agreement. (5) As a concession to Guizot,Aberdeen dropped the demand for a mutual right of search and negotiated the Convention of 1845, establishing a system of joint-cruising.
