40K Lore: Lord Solar Macharius


Today we celebrate the greatest Astra Militarum commander of all time – Macharius and his legendary crusade.

Lord Commander Solar Macharius (356-400.M41) is widely regarded as the greatest Imperial Guard commander in Imperial history. His conquests, known as the Macharian Crusade, beginning in 392.M41, reached the edge of galactic space, and brought nearly a thousand worlds under Imperial control within only seven years of fighting. He was one of the greatest Living Saints in Imperial history and is considered the greatest Saint of the Imperial Guard.


Macharius rose to prominence in the early Forty-First Millennium during a time when the Imperium’s power was finally recovering from the devastating Age of Apostasy. Born in 356.M41 as the heir of the Planetary Governor of DoniaPella, Macharius was already a renowned Imperial Guard General by his early 20s. His brilliant leadership during the crushing of the Roxane Rebellion, where he rescued Lord Commander Solar Phillips, brought Macharius to the attention of the High Lords of Terra. Phillips recognized the genius of Macharius and took him under his wing, naming him his successor as Lord Commander Solar. It was also during this time that Macharius met the men who would go on to lead his armies: SejanusBorgen CrassusTarkaArrianLysander of Choripoli, and Cyrus of Larrentine. In 386.M41 Lord Solar Phillips was killed in the Lemort Landings and Macharius inherited his prestigious command, the youngest in the history of the position. He traveled to Terra for the first and last time during his inauguration. Using his new position, he oversaw a string of early conquests on the worlds of Lands EndMorbellum, and Jalfrezi III with his Donian Army. It was at this point that Macharius expressed his desire to launch the greatest Crusade since the Great Crusade at the dawn of the Imperium itself.

By most accounts, Macharius indeed fulfilled his wish and nearly one thousand worlds were claimed over the course of the Macharian Crusade. At the edge of the galaxy Macharius prepared to move onwards but his armies, never beaten by the enemy, wavered and crumbled at the prospect of exploring the psychic darkness at the galaxy’s edge. The conquests of Macharius came to an end, and according to Imperial records on the return trip he died of a jungle fever contracted on Jucha, while others say he willingly died so he could rest with the old heroes of the Imperium who would not balk at danger, unlike his men.

The truth however is far darker, and was seemingly covered up by Imperial authorities after his death. While battling his traitorous ex-protege Richter, who is said to have turned to worshiping Nurgle, Macharius contracted several deadly diseases besieging the traitor world of Loki and may have only had weeks to live. Macharius was eventually able to kill Richter, but was in turn killed by a member of the Officio Assassinorum disguised as an Inquisitorial Stormtrooper with the cooperation of Inquisitor Drake, who may have been sabotaging Macharius’ war effort on Loki. However to suppress the truth of the incident, the Assassin then killed Drake as well and the reasons and figures behind this conspiracy are left ambiguous.

After his death, Macharius was canonized as a Saint of the Imperium. No man has ever conquered more worlds nor won so many battles, not since the legendary days of the Great Crusade itself. So great were his accomplishments that the Ecclesiarchy declared Macharius a Saint and renamed his homeworld Macharia in his honor.



Macharius was a ruthless leader, always pushing his men to greater feats of daring and courage. He would often bombard planets from orbit and destroy the native population, but he spared some worlds if they impressed him with their courage and resolve. He was a very spiritual man, campaigning in the name of the Emperor and not just for his own selfish gain. He had consuming desires, such that they were his guiding force throughout his conquest. He was also followed by a trail of miracles, one such being that a bolter shell embedded itself in his chest but failed to detonate.

He commanded many forces and he had an equally notable general, Sejanus, who was always at his side. Sejanus was the one who told Macharius that his men would follow him no further, that Ultima Macharia was the end; they would not venture into the Halo Zone, outside the reach of the Astronomican. Macharius wept, tears of rage and sorrow, as he heard of his soldiers’ refusal to go on. He remained bitter to his men for refusing to go on, drinking himself into a drunken stupor and decrying that he did not have braver heroes at his command.


Macharius had two vessels as his flagships in the campaign. First, he used the Mars Class Battle Cruiser Pax Imperium, but when that was heavily damaged at the battle of Charaxdis, Macharius was convinced to move his flagship to the Emperor Class Battleship Lord of Light. Macharius always preferred speed and agility, but his generals would not let him move off the heavy ship. On Macharius’s death, the Lord of Light was decommissioned and placed in orbit above the shrine world of Macharia as a tribute in his honour.

Macharius was the second to hold the title of Lord Commander Solar. His brilliance as a general is further acknowledged as the Macharian Cross, awarded for innovative thinking in battle, is named after him.

    The greatest saint of the Imperial Guard is Ollianus Pius.

    • DarkSeren1ty

      Indeed. That was the impetus the Emperor needed to end Horus’ life.

  • Davor Mackovic

    2555 days to conquer more than 1000 worlds? That is what 2 days a world? How long does it take to travel from world to world? This just doesn’t add up.

    What am I missing here?

    • polyquaternium7

      most likely there are multiple worlds in a single star sytem, Macharius also had multiple battle groups, attacking several star systems at once in a single subsector would speed up the process of conquest

    • LordKrungharr

      Maybe his navigators could exit the warp before they entered the warp but in a different point in space? That would save some time.

    • 6Cobra

      Macharius’ fleets were equipped with a secret device, called a “suspension of disbelief.”

      *Quite a few* things in the 40K background don’t add up when you apply pretty much any kind of realistic metrics.

        He win all those victories the same way Eisenhower technically won all his battles. He was a strategist, and did not need to be present at every battle.

  • Mr_Pickles

    “The meaning of victory is not to merely defeat your enemy but to destroy him, to completely eradicate him from living memory, to leave no remnant of his endeavors, to crush utterly his achievement and remove from all record of his every trace of existence. From that defeat no enemy can ever recover. That is the meaning of victory.” – Lord Solar Macharius

    Space Alexander!

  • Darth Bumbles

    If the bloke was infected with a host of diseases by a worshipper of Nurgle, killing him was probably for the best – the gifts of Nurgle have a habit of turning the infected into either a zombie or a rabid devotee of Nurgle.

  • DJ860

    Some of the names of these planets are brilliant. He conquered “Jalfrezi III”

      Shall we just split the bill?

  • euansmith

    He doesn’t sound to bright. He cuts a swath through the Galaxy until he nears its edge. He then gives up in a huff and dies on the way home. Why didn’t he just turn left or right, and continue his rampage around the spiral of the Galaxy?

    After all, the Imperium only controls around one million worlds from around 300 Billion star systems in the Galaxy. There are plenty more worlds left to conquer.

    I know he is supposed to be an Alexander analogue, but it is a pretty poor showing for a supposed strategic genius; rather more Stannis Baratheon.

    • Morgrim

      Strategic brilliance doesn’t always translate to good people skills, common sense or wisdom. I suspect he’d decided to go to the edge of the galaxy some time before and was desperately fixated on finishing the job.

      • euansmith

        Typical “Psycho Boss” behaviour 😀 Blames the “little people” for not sharing his vision.
