In May of that year he was appointed Minister Plenipotentiary to France, and was received in Paris with enthusiastic demonstrations of respect. His marked exhibition of sympathy with the French Republic displeased the administration. John Jay had been sent to negotiate a treaty with England, and the course pursued by Monroe was considered injudicious, as tending to throw serious obstacles in the way of the proposed negotiations. On the conclusion of the treaty his alleged failure to present it in its true character to the French government excited anew the displeasure of the cabinet; and in August, 1796, he was recalled under an informal censure.

On his return to America he published a 'View of the conduct of the Executive in the Foreign Affairs of the United States,' which widened the breach between him and the administration, but socially Monroe remained upon good terms with both Washington and Jay.

He was Governor of Virginia from 1799 to 1802 and at the close of his term was appointed Envoy Extraordinary to the French government to negotiate, in conjunction with the resident minister, Mr. Livingston, for the purchase of Louisiana, or a right of depot for the United States on the Mississippi. Within a fortnight after his arrival in Paris the ministers secured, for $15,000,000, the entire territory of Orleans and district of Louisiana.

In the same year he was commissioned Minister Plenipotentiary to England, and endeavored to conclude a convention for the protection of neutral rights, and against the impressment of seamen. In the midst of these negotiations he was directed to proceed to Madrid as Minister Extraordinary and Plenipotentiary to adjust the difficulties between the United States and Spain, in relation to the boundaries of the new purchase of Louisiana. In this he failed, and in 1806 he was recalled to England to act with Mr. Pickney in further negotiation for the protection of neutral rights. On the last day of that year a treaty was concluded, but because of the omission of any provision against the impressment of seamen, and its doubtfulness in relation to other leading points the president sent it back for revisal. All efforts to attain this failed and Monroe returned to America.

The time was approaching for the election of a president, and a considerable body of the Republican party had brought Monroe forward as their candidate, but the preference of Jefferson for Madison was well known and of course had its influence. Monroe believed that the rejection of the treaty and the predilection expressed for his rival indicated hostility on the part of the retiring President, and a correspondence on the subject ensued.

Jefferson candidly explained his course and assured him that his preference was based solely upon solicitude for the success of the party, the great majority of which had declared in the favor of Madison. The misunderstanding ceased and Monroe withdrew from the canvass. In 1810 he was again elected to the general assembly of Virginia, and in 1811 once more Governor of the State.

In the same year he was appointed Secretary of State by President Madison, and after the capture of the capitol in 1814, he was appointed to take charge of the war department, being both Secretary of State and Secretary of War at once. He found the treasury exhausted and the national credit at the lowest ebb, but he set about the task of infusing order and efficiency into the departments under his charge, and proposed an increase of 40,000 men in the army by levying recruits throughout the whole country.

His attention was also directed to the defence of New Orleans, and finding the public credit completely prostrated, he pledged his private means as subsidary to the credit of the Government, and enabled the city to successfully oppose the forces of the enemy. He was the confidential adviser of President Madison in the measures for the re-establishment of the public credit of the country and the regulation of the foreign relations of the United States, and continued to serve as Secretary of State until the close of Madison's term in 1817.

In that year he succeeded to the Presidency himself, by an electoral vote of 183 out of 217, as the candidate of the party now generally known as Democratic.

His Cabinet was composed of some of the ablest men in the country in either party. Soon after his inauguration President Monroe made a tour through the Eastern and Middle States, during which he thoroughly inspected arsenals, naval depots, fortifications and garrisons; reviewed military companies, corrected public abuses, and studied the capabilities of the country with reference to future hostilities.
