In 1819, Bradish was commissioned by United States Secretary of State John Quincy Adams, under U.S. President James Monroe, to pursue a treaty with the Ottoman Empire on commerce and shipping in the Mediterranean. Up till that point, Philadelphian David Offley was interceding, on behalf of American shippers, with the Empire's regencies along the Barbary Coast, i.e., Algiers, Libya, Tunis, etc., His effectiveness was limited because the U.S had no official relations with the Empire, even after the conclusion of the First and the Second Barbary Wars. The treaty terms demanded by Halet Efendi, the Ottoman foreign minister, were unacceptable to the U.S. Because Halet was thought to have contributed to a Greek insurrection in 1821 by poor policy, displeasing the Sultan, he was banished from the Empire's capital of Constantinople (Istanbul) and executed in 1822.
