Mackinder

National Security Advisor Zbigniew Brezinski updated MacKinder, arguing that "geopolitics has moved from the regional to the global dimension, with preponderance over the entire Eurasian continent serving as the central basis for global primacy."

Around 1900, at the high tide of the British Empire, an English geographer, Sir Halford Mackinder, started the modern study of geopolitics by publishing a highly influential article arguing that the construction of the 5,000-mile-long Trans-Siberian Railway from Moscow to Vladivostok was the beginning of a merger of Europe and Asia.

In recent weeks, Chinese analysts have repeatedly cited the century-old writings of a British geographer, Sir Halford John Mackinder.

For nearly 100 years, the geopolitical theories of an obscure Victorian geographer, Sir Halford Mackinder, have had a profound influence on a succession of leaders who sought to build or break empires in Eurasia — including Adolf Hitler, U.S. national security adviser Zbigniew Brzezinski and, most recently, Vladimir Putin.

In an academic essay published in 1904, when the Trans-Siberian Railway was completing its 5,700-mile crawl from Moscow to Vladivostok, Mackinder argued that future rails would knit Eurasia into a unitary landmass that, along with Africa, he dubbed the tri-continental "world island."
