The Problem of Asia (Alfred Thayer Mahan, 1900)
[[File:Mahan Problem of Asia 1900.png|thumb|center|600px|This map depicts the world as divided by geostrategist Alfred Thayer Mahan in his 1900 piece The Problem of Asia. Asia is divided along the 30 north and 40 north parallels, represented here by green lines. In between the 30th and 40th parallel is what Mahan termed the "Debatable and debated ground," subject to competition between the land powers and sea powers.

Alfred Thayer Mahan was an American Navy officer and president of the U.S. Naval War College. He is best known for his Influence of Sea Power upon History series of books, which argued that naval supremacy was the deciding factor in great power warfare. In 1900, Mahan's book The Problem of Asia was published. In this volume he laid out the first geostrategy of the modern era.

The Problem of Asia divides the continent of Asia into 3 zones:
 * A northern zone, located above the 40th parallel north, characterized by its cold climate, and dominated by land power;
 * The "Debatable and Debated" zone, located between the 40th and 30th parallels, characterized by a temperate climate; and,
 * A southern zone, located below the 30th parallel north, characterized by its hot climate, and dominated by sea power.

The Debated and Debatable zone, Mahan observed, contained two peninsulas on either end (Anatolia and the Korean Peninsula), the Suez Canal, Palestine, Syria, Mesopotamia, two countries marked by their mountain ranges (Iran and Afghanistan), the Pamir Mountains, the Himalayas, the Yangtze, and Japan. Within this zone, Mahan asserted that there were no strong states capable of withstanding outside influence or capable even of maintaining stability within their own borders. So whereas the political situations to the north and south were relatively stable and determined, the middle remained "debatable and debated ground."

North of the 40th parallel, the vast expanse of Asia was dominated by the Russian Empire. Russia possessed a central position on the continent, and a wedge-shaped projection into Central Asia, bounded by the Caucasus Mountains and Caspian Sea on one side and the mountains of Afghanistan and Western China on the other side. To prevent Russian expansionism and achievement of predominance on the Asian continent, Mahan believed pressure on Asia's flanks could be the only viable strategy pursued by sea powers.

South of the 30th parallel lay areas dominated by the sea powers – the United Kingdom, the United States, Germany and Japan. To Mahan, the possession of India by the United Kingdom was of key strategic importance, as India was best suited for exerting balancing pressure against Russia in Central Asia. The United Kingdom's predominance in Egypt, China, Malaysia, Australia, Canada and South Africa was also considered important.

The strategy of sea powers, according to Mahan, ought to be to deny Russia the benefits of commerce that come from sea commerce. He noted that both the Turkish Straits and Danish Straits could be closed by a hostile power, thereby denying Russia access to the sea. Further, this disadvantageous position would reinforce Russia's proclivity toward expansionism in order to obtain wealth or warm water ports. Natural geographic targets for Russian expansionism in search of access to the sea would therefore be the Chinese seaboard, the Persian Gulf, and Asia Minor.

In this contest between land power and sea power, Russia would find itself allied with France (a natural sea power, but in this case necessarily acting as a land power), arrayed against Germany, Britain, Japan, and the United States as sea powers. Further, Mahan conceived of a unified, modern state composed of Turkey, Syria, and Mesopotamia, possessing an efficiently organized army and navy to stand as a counterweight to Russian expansion.

Further dividing the map by geographic features, Mahan stated that the two most influential lines of division would be the Suez Canal and Panama Canal. As most developed nations and resources lay above the North–South divide, politics and commerce north of the two canals would be of much greater importance than those occurring south of the canals. As such, the great progress of historical development would not flow from north to south, but from east to west, in this case leading toward Asia as the locus of advance.
