John O'Sullivan was born in November, 1813. He became a journalist and was the founder and editor of the United States Magazine and Democratic Review (1837-1846). He was also the editor of the New York Morning News (1844-46).
In an editorial the in United States Magazine and Democratic Review in July 1845, O'Sullivan became the first person to use the term "manifest destiny" to encourage the spirit of expansionism. Over the following years the Manifest Destiny doctrine claimed that it should be the objective of the United States to absorb all of North America. This expansionism eventually ended in the acquisition of Texas, Oregon and California.
In 1854 O'Sullivan became minister to Portugal. A post he held until 1858. John O'Sullivan died on 24th February, 1895.
California will, probably, next fall away from the loose adhesion which, in such a country as Mexico, holds a remote province in a slight equivocal kind of dependence on the metropolis. Imbecile and distracted, Mexico never can exert any real government authority over such a country. The impotence of the one and the distance of the other, must make the relation one of virtual independence; unless, by stunting the province of all natural growth, and forbidding that immigration which can alone develop its capabilities and fulfill the purposes of its creation, tyranny may retain a military dominion, which is no government in the legitimate sense of the term.
In the case of California this is now impossible. The Anglo-Saxon foot is already on its borders. Already the advance guard of the irresistible army of Anglo-Saxon emigration has begun to pour down upon it, armed with the plough and the rifle, and marking its trail with schools and colleges, courts and representative halls, mills and meetinghouses. A population will soon be in actual occupation of California, over which it will be idle for Mexico to dream of dominion. They will necessarily become independent. All this without agency of our government, without responsibility of our people - in the natural flow of events, the spontaneous working of principles, and the adaptation of the tendencies and wants of the human race to the elemental circumstances in the midst of which they find themselves placed.
And they will have a right to independence - to self-government - to the possession of the homes conquered from the wilderness by their own labors and dangers, sufferings and sacrifices - a better and a truer right than the artificial title of sovereignty in Mexico, a thousand miles distant, inheriting from Spain a title good only against those who have none better. Their right to independence will be the natural right of self-government belonging to any community strong enough to maintain it - distinct in position, origin and character, and free from any mutual obligations of membership of a common political body, binding it to others by the duty of loyalty and compact of public faith. This will be their title to independence; and by this title, there can be no doubt that the population now fast streaming down upon California
will both assert and maintain that independence.
Whether they will then attach themselves to our Union or not, is not to be predicted with any certainty. Unless the projected railroad across the continent to the Pacific be carried into effect, perhaps they may not; though even in that case, the day is not distant when the empires of the Atlantic and Pacific would again flow together into one, as soon as their inland border should approach each other. But that great work, colossal as appears the plan on its first suggestion, cannot remain long unbuilt.
Its necessity for this very purpose of binding and holding together in its iron clasp our fast-settling Pacific region with
that of the Mississippi Valley - the natural facility of the route - the ease with which any amount of labor for the construction can be drawn in from the overcrowded populations of Europe, to be paid in the lands made valuable by the progress of the work itself - and its immense utility to the commerce of the world with the whole eastern coast of Asia, alone almost sufficient for the support of such a road - these considerations give assurance that the day cannot be distant which shall witness the conveyance of the representatives from Oregon and California to Washington within less time than a few years ago was devoted to a similar journey by those from Ohio; while the magnetic telegraph will enable the editors of the San Francisco Union, the Astoria Evening Post, or the Nootka Morning News, to set up in type the first half of the President's inaugural before the echoes of the latter half shall have died away beneath the lofty porch of the Capitol, as spoken from his lips.
Away, then, with all idle French talk of balances of power on the American Continent. There is no growth in Spanish America! Whatever progress of population there may be in the British Canadas, is only for their own early severance of their present colonial relation to the little island 3,000 miles across the Atlantic; soon to be followed by annexation, and destined to swell the still accumulating momentum of our progress.
And whosoever may hold the balance, though they should cast into the opposite scale all the bayonets and cannon, not only of France and England, but of Europe entire, how would it kick the beam against the simple, solid weight of the 250, or 300 million - and American millions - destined to gather beneath the flutter of the stripes and stars, in the fast hastening year of the Lord 1945!
