A chain of extinct volcanoes that mostly lie under water stretches across the Pacific from Hawaii to Kamchatka. This chain, known as the Hawaiian-Emperor Chain, is the trail left by a volcanic hotspot. But why does it change direction in the middle? An international team of researchers, including members of GEOMAR Helmholtz Centre for Ocean Research Kiel, the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, and FAU have found an explanation in large-scale tectonic changes that took place around 50 million years ago. Their study has recently been published in the international journal Nature Geoscience.*

The model is very simple in principle. In certain places in the earth’s core, especially hot material rises towards the earth’s crust in what is known as a plume. It melts through the tectonic plates like a blowtorch, depositing magma on the surface. A volcano is formed. However, over time the plates move away from the volcanic hotspot, taking the volcano with them. As the plume continues to expel hot material, a second volcano forms next to the first which is now extinct. In this way, over millions of years a chain of volcanoes is formed. One of the most famous examples of this is in Hawaii, where the chain starts with today’s islands and extends in an almost perfectly straight line towards the north-west. The Hawaiian Islands mark the location of the active hotspot, while the islands and under-water mountains become older and older the further you go to the north-west.

Yet as is so often the case in nature, the reality is more complex than the model. Around 3500 kilometres north-west of Hawaii the chain of volcanoes suddenly changes direction and goes north. From here onwards the submerged mountains are known as the Emperor Chain. ‘Until now there have been several theories as to the cause of the Hawaiian-Emperor bend, but no really reliable explanations. We have found evidence that the Pacific Plate underwent large-scale deformation between 47 and 53 million years ago and that the bend in the Hawaiian-Emperor Chain occurred at the same time. We have come to the conclusion that large-scale changes in plate tectonics and convection currents in the mantle that happened around 50 million years ago could be the cause,’ explains Prof. Dr. Kaj Hoernle from GEOMAR Helmholtz Centre for Ocean Research Kiel. He and nine other researchers from Germany, the Netherlands, Australia, the United Kingdom and the USA have now published their findings in the international journal Nature Geoscience.

The researchers were helped by volcanoes with some interesting names. North of the Hawaiian Chain is a range of underwater mountains called the Musicians Seamounts which are named after composers such as Beethoven, Bach or Donizetti. For a long time it was thought that these seamounts were also created by a hotspot. In their study the researchers dated and examined many samples from the Musicians Seamounts using geochemical methods for the first time. They discovered that these underwater mountains do not show a progression from young to old as would be expected for volcanoes formed by a hotspot. ‘The samples that we analysed were mostly between 47 and 53 million years old,’ explains lead author Dr. John O’Connor, a researcher at GeoZentrum Nordbayern at FAU who collaborates with colleagues from Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research and the University of Amsterdam in his research on the dynamics of the earth’s crust.

‘The geochemical analyses also had a surprise in store for us. The composition of the samples from the Musicians Seamounts is more similar to volcanoes that form in mid-ocean ridges that those that grow over a hotspot,’ explains Dr. Folkmar Hauff from GEOMAR, co-author of the study. It is possible that around 50 million years ago large cracks appeared in the Pacific Plate, leading to the formation of these volcanoes. We know from previous studies that this was also the time when the plates in the north and west of the Pacific Ocean began to overlap. The Izu-Bonin-Mariana Arc and the Aleutian Arc are impressive testaments to these processes. ‘Our analyses of the Musicians Seamounts show that all of these events could be related, and that these large-scale changes probably also caused the bend in the Hawaiian-Emperor Chain,’ says Professor Hoernle.

The annals of ancient history are replete with tales of conquest, empire, and the clash of civilizations, but few figures loom as large or cast as long a shadow as Alexander the Great and Darius III, whose epochal confrontations would reshape the political, cultural, and demographic landscape of the ancient world. Born in 356 BCE in Pella, the ancient capital of Macedon, Alexander was the scion of a formidable military dynasty, his father Philip II having transformed the once-peripheral kingdom into a dominant power through a series of shrewd military and diplomatic maneuvers. Tutored by the legendary philosopher Aristotle and forged in the crucible of his father's campaigns, the young Alexander would quickly prove himself a prodigy of martial prowess and strategic acumen, ascending to the throne in 336 BCE after his father's assassination and promptly consolidating his grip on the Hellenic world through a mixture of deft diplomacy and decisive military action.

To the east, however, loomed the vast and formidable Achaemenid Persian Empire, a behemoth that stretched from the shores of the Aegean to the foothills of the Hindu Kush, encompassing an estimated population of 50 million people and a land area of approximately 8 million square kilometers. At its helm sat Darius III, a ruler of no small pedigree himself, tracing his lineage back to the legendary Achaemenid kings Cyrus the Great and Darius I. Commanding an army that may have numbered up to 200,000 men, drawn from the far-flung satrapies of his empire and bolstered by a formidable array of chariots, cavalry, and war elephants, Darius presented a daunting obstacle to Alexander's dreams of eastern conquest, the Persian emperor's vast resources and numerical superiority seeming to render any attempt at invasion a fool's errand.

Undeterred by the odds arrayed against him, Alexander would launch his audacious campaign against the Persian Empire in 334 BCE, leading an army of some 50,000 battle-hardened Macedonian and Greek troops across the Hellespont and into the heart of Persian territory. In a series of stunning victories, most notably at the battles of Granicus, Issus, and Gaugamela, Alexander would repeatedly demonstrate his tactical genius and the superiority of his troops, the Macedonian phalanx, with its longer spears and tighter formation, proving more than a match for the Persian infantry, while Alexander's elite Companion Cavalry would time and again break through the enemy lines and wreak havoc on the Persian flanks and rear.

As word of Alexander's victories spread, the Persian Empire began to unravel, with many of its far-flung provinces and satrapies defecting to the Macedonian conqueror or rising in open revolt against Darius's rule. The Persian emperor, his armies shattered and his authority crumbling, was forced to flee into the eastern reaches of his empire, his fate ultimately sealed by the treachery of his own subordinates, who assassinated him in the summer of 330 BCE. With Darius's death, Alexander found himself the master of the largest empire the world had yet seen, his dominion stretching from the Adriatic Sea to the Indus Valley and encompassing an estimated 5.2 million square kilometers and a population of over 30 million people.

Yet even as he stood at the pinnacle of his power, Alexander's insatiable ambition and restless spirit would not let him rest on his laurels. Pushing ever eastward, he would lead his army on a grueling campaign of conquest and exploration, subduing the fierce tribes of Bactria and Sogdiana and crossing the Hindu Kush into the valleys of the Indus, where he would clash with the formidable armies of King Porus at the Battle of the Hydaspes. Though victorious, Alexander would ultimately be forced to turn back at the Beas River, his troops, exhausted by years of campaigning and demoralized by the prospect of further battles against the vast armies of the Nanda Empire, refusing to go any further.

Returning to Babylon, the great city he had chosen as his capital, Alexander would devote his final years to consolidating his rule and laying the foundations for a new, syncretic empire that would blend the best of Persian and Hellenic culture. However, his grand designs would be cut tragically short by his untimely death in June of 323 BCE, likely from a combination of fever, exhaustion, and excessive drinking. The shockwaves of Alexander's sudden demise would reverberate across his vast empire, as his generals and satraps, the so-called Diadochi, or "successors," jockeyed for power and position in the vacuum left by their fallen leader.

In the bloody wars of succession that followed, Alexander's empire would be carved up into a series of competing Hellenistic kingdoms, each ruled by a dynasty of Macedonian or Greek descent. In the east, Seleucus, one of Alexander's most capable generals, would establish the Seleucid Empire, a vast domain that stretched from Anatolia to the borders of India, while in Egypt, Ptolemy, another of Alexander's inner circle, would found the Ptolemaic dynasty, which would rule the land of the Nile for nearly three centuries. Other Diadochi, such as Antigonus Monophthalmus and his son Demetrius Poliorcetes, would stake their claims to various parts of Alexander's empire, their internecine struggles and shifting alliances defining the political landscape of the Hellenistic world for generations to come.

Yet even as Alexander's political legacy fractured and dissolved, his cultural and intellectual impact would endure, the Hellenistic kingdoms he had spawned acting as conduits for the spread of Greek language, art, and philosophy across the Near East and beyond. The great libraries and museums of Alexandria, the flourishing of Hellenistic science and mathematics, and the syncretism of Greek and local religious traditions all attest to the profound and lasting influence of Alexander's conquests, which opened up new horizons of cultural exchange and helped lay the foundations for the cosmopolitan, globalized world of late antiquity.

In the end, the story of Alexander the Great and Darius III is one of epochal confrontation and transformation, a tale of two titans whose clash would echo through the ages and reshape the very fabric of the ancient world. It is a story of ambition and conquest, of the rise and fall of empires, and of the enduring power of ideas to transcend the boundaries of nation and culture. And while the empires they forged would eventually crumble and fall, the legacy of these two towering figures would endure, etched indelibly into the annals of history and the collective memory of civilization.
