The Turkic Khaganate is a vast empire from Manchuria and the Chinese wall to the Black Sea.

It is impossible to govern the whole khaganate from a single capital, so while the eastern part is directly ruled by the khagan, the western part is governed by a yabgu (vassal) in behalf of the khagan.

The capital of the west is Ordukent (Suyab) in present day Kyrgyzistan.

Istemi, who was the fist khagan's brother, is the first yagbu and Tardu (İstemi's son) is the second.

The western Turk empire continues to thrive under Tardu, who succeeds his father in 575.

The events of the reign of Al-Mundhir IV are mostly obscure, except for the sack and razing of Hirah by the Ghassanids under al-Mundhir III ibn al-Harith in 575.

A Yemenite appeal to Persia for aid leads in 575 to a relatively brief Persian occupation of Yemen and the end of Christian power in South Arabia.

The ravages of the Lombards have rendered it very difficult to communicate with the emperor at Constantinople, who claims the privilege of confirming the election of the popes.

Hence there has been a vacancy of nearly eleven months between the death of John III and the arrival of the imperial confirmation of the election, on June 2, 575, of Pope Benedict, the son of a man named Boniface, called Bonosus by the Greeks.

The Assassination of Sigebert I and the Survival of Childebert II (575 CE)

By 575 CE, Sigebert I has nearly defeated Chilperic I, seizing most of Neustria and being proclaimed king by Chilperic's subjects at Vitry, a key Neustrian stronghold. However, at the moment of his greatest triumph, he is assassinated by agents of Fredegund, abruptly altering the course of Frankish history.

1. The Acclamation of Sigebert at Vitry (575 CE)

• With Chilperic in hiding at Tournai, Sigebert is declared king of Neustria by its nobles and subjects.
• Vitry, a significant Neustrian seat of power, is chosen over Arras, where Chilperic had ruled.
• Sigebert is raised on the shield, following Frankish royal tradition, symbolizing his official acceptance as king.

2. The Assassination by Fredegund’s Agents

• At the moment of his triumph, two assassins, reportedly acting on orders from Fredegund, strike him down.
• The assassination is swift and unexpected, preventing him from fully consolidating his rule over Neustria.
• With Sigebert’s death, Chilperic is saved from certain defeat, allowing him to reclaim Neustria.

3. The Struggle for Childebert II’s Inheritance

• Sigebert’s young son, Childebert II, is now the rightful king of Austrasia.
• Chilperic attempts to seize his lands, taking advantage of Sigebert’s sudden death.
• However, Guntram, King of Burgundy, intervenes to protect Childebert, preventing Chilperic from claiming Austrasia.
• Guntram acts as a mediator, ensuring that the Merovingian civil war does not escalate further.

4. The Aftermath and the Continued Blood Feud

• Brunhild, Sigebert’s widow, becomes the regent for Childebert II, taking control of Austrasia.
• She vows vengeance against Fredegund and Chilperic, ensuring that their rivalry continues.
• The conflict between Neustria and Austrasia persists, dominating Frankish politics for decades.

Conclusion: A Turning Point in the Merovingian Civil War

The assassination of Sigebert I in 575 CE is a pivotal moment in Frankish history, dramatically shifting the balance of power:

• Fredegund’s cunning saves Chilperic from certain defeat, allowing him to regain control of Neustria.
• Childebert II, under the protection of Guntram, survives to rule Austrasia, keeping the Merovingian civil war alive.
• Brunhild and Fredegund’s rivalry intensifies, ensuring decades of dynastic bloodshed, political intrigue, and assassinations.

Sigebert’s premature death prevents the unification of Austrasia and Neustria, prolonging the fragmentation and internecine conflicts that define the Merovingian dynasty.

King Jinheung, one of the greatest kings of Silla, has been responsible for expanding Silla territory immensely.

In 576 BCE, the Hwarang Organization is established; it will later play a huge role in the unification of Korea’s three kingdoms.

Jinheung, who dies in this year at forty-three after ruling for thirty-seven years, is succeeded by his second son, Prince Sa-Ryun, who becomes King Jinji.

The alliance between the Persians and the Western Turks has, inevitably, become a source of possible friction, and the Western Turks have sometimes acted as an ally of Constantinople in the war that had begun in 572.

The Turks, angered by the Romans’ treaty with the Avars, not only break off their alliance with Constantinople in 576 but also seize a Roman stronghold in the Crimea.

The Roman-Persian war that had begun five years earlier ends in 576 with Persia’s defeat at Melitene.

Chilperic I’s War Against Guntram and His Gains in Austrasia (575–584 CE)

Following the assassination of Sigebert I in 575 CE, Chilperic I of Neustria takes advantage of the ensuing instability in Austrasia, where Sigebert’s young son, Childebert II, is now king under the protection of Guntram, King of Burgundy. Chilperic sees an opportunity to expand Neustrian power at the expense of Austrasia and Burgundy.

1. War with Guntram and the Seizure of Austrasian Territory

• Guntram, King of Burgundy, positions himself as protector of his nephew, Childebert II, seeking to prevent Neustrian expansion.
• Chilperic, however, launches an aggressive campaign, forcing Guntram to defend Childebert’s eastern Frankish kingdom.
• Chilperic successfully takes Tours and ...

...

• Poitiers from Austrasia, extending Neustrian influence into central Gaul.
• He also captures several locations in Aquitaine, consolidating his position in the region.

2. Fostering Discord in Austrasia

• Chilperic does not merely rely on military conquest—he also engages in political manipulation to destabilize Austrasia.
• He fosters discord among the Austrasian nobility, seeking to weaken Childebert’s rule during his minority.
• This tactic allows him to maintain pressure on his eastern rivals, further undermining the unity of the Frankish realms.

3. The Growing Power Struggle in the Frankish Kingdoms

• With Guntram defending Childebert II and Chilperic expanding Neustrian influence, the Frankish kingdoms remain locked in a prolonged struggle for dominance.
• Meanwhile, Brunhilda, the widow of Sigebert, works to protect her son’s claim while dealing with internal opposition in Austrasia.
• Chilperic’s growing power threatens the balance of power in Frankish Gaul, but his reign is cut short by his assassination in 584 CE, allegedly orchestrated by his own political enemies.

Conclusion: A Temporary Neustrian Expansion

Chilperic’s recovery of Tours, Poitiers, and parts of Aquitaine in the late 570s and early 580s marks a significant Neustrian territorial gain. However, his sudden assassination in 584 CE will leave his wife, Fredegund, and their young son, Chlothar II, vulnerable to retaliation from their rivals in Austrasia and Burgundy.

Despite his temporary success, Chilperic’s wars further fragment the Merovingian realm, ensuring that dynastic feuds and territorial struggles will persist for decades to come.
