Trajan Gates
In 986, one of the most influential battles in world history took place—the Battle of Trajan’s Gates—in a mountain pass 60 km from Sofia on the road to Plovdiv. The battle was between the forces of the Bulgarian Tsar Samuel and the forces of the Byzantine Emperor Basil II. Surprisingly, the Bulgarians won, and as a result gained 30 more years of independence—enough time to shape their religion and beliefs, strengthen the spiritual center in Ohrid, and maintain a cultural and religious golden age that inspired future generations. In the end, Basil II defeated Samuel in 1014 and subjugated his kingdom, but what had happened in the Balkans during those years could no longer be reversed.
The sequence of events that led to this battle was as follows: in 986, ten years after Basil II’s ascension to power in Byzantium (he had replaced John Tzimiskes as emperor and ruled for 50 years), he managed to consolidate his rule militarily, politically, and socially, and decided to act against the Bulgarians who harassed his forces. The locals in the Balkans were a rival to the Byzantine Empire’s hegemony. Basil II set out on a military campaign with 20,000 soldiers from Adrianople, through Plovdiv to Sofia, with the aim of besieging and conquering Sofia, and from there continuing to the strongholds of the Komitopuli brothers in the western Balkans.
But the siege of Sofia, which lasted twenty days, failed miserably. The besieged managed to break out of the city and damage the siege engines, and supplies did not arrive on time. In addition, reports began to arrive that the Bulgarian Tsar Samuel was stationed in the Rila Mountains with large military reserves threatening the Byzantines’ flank. The Byzantine army retreated from Sofia and encamped along the way in the valley of Ihtiman (it is assumed that the Bulgarian army encamped in the Kostenets valley nearby). At night, rumors began to spread in the Byzantine camp about an imminent Bulgarian attack, and this news caused panic. In the morning, an unorganized retreat of the troops through the mountain passes began; the Bulgarians under Samuel’s leadership took advantage of this, attacked the Byzantine camp, and caused even greater panic. The Byzantine army disintegrated, and the scattered units were trapped in the forests and valleys of the mountain pass. The army was almost completely destroyed as battles raged throughout the day. Only the Armenian elite unit managed to rescue itself and the emperor, while suffering heavy losses.
The defeat at the gates of Trajan caused a sharp decline in the emperor’s status and sparked a rebellion against him in Asia Minor, led by the general Bardas Phokas, which lasted for three years. Following this, Basil II appealed to the Russians for help, offering his sister in marriage to Prince Vladimir, along with estates, and granting commercial and religious privileges to the Russian kingdom, as part of a deal that included the conversion of the Russians to Orthodox Christianity. And so it happened: in 988, Prince Vladimir was baptized into Christianity, and the Russians sent 6,000 soldiers to assist Basil II—these were the decisive force in suppressing the rebellion. From that time onward, Russia became Orthodox Christian and aligned with Byzantium.
On the Bulgarian side, following the battle at the Trajan Gates, Samuel moved the capital from Preslav in northeastern Bulgaria to Ohrid in Macedonia, which once again became the spiritual and religious center of the Slavic Balkans. The Bulgarians occupied large territories in northern Greece and the western and eastern Balkans, including areas of Albania, Serbia, Montenegro, Bosnia, and Croatia. Independent Slavic kingdoms began to emerge in these regions, subject to the authority of the patriarchate in Ohrid, which later became an archbishopric but maintained its important role and influence.
It so happens that there were also forces at work behind the scenes. The day of the battle, August 17, was considered sacred by the Bulgarian Bogomils, who used to gather in the days before it at the heights of the Rila Mountains (a tradition later adopted by the Danube White Brotherhood). Hence the time of the battle was considered blessed by Samuel’s soldiers, many of whom were Bogomils, and part of their success likely stemmed from religious enthusiasm.
The connection to the Bogomils explains Samuel’s choice of the Rila Mountains as his power base. The assembling of his fighting force took a few weeks and began even before the siege, upon receiving reports of the Byzantine army’s advance toward Sofia. Gathering points for the soldiers were likely established during that time, which became the villages at the foot of the mountains, especially Raduil and Maritsa.
It is likely there was another reason for gathering in the Rila Mountains and for choosing the specific date of the battle: Saint John of Rila is the patron saint of Bulgaria, and the location of his monastery in the heart of the Rila Mountains was a site of pilgrimage. His feast day is August 18—one day after the battle—so the choice of date may have had symbolic importance for all Bulgarians. The spiritual center of the empire was the Rila Mountains and the Rila Monastery, so it was fitting that the Bulgarian army would gather near there. In other words, the Bulgarian army had a strong base of popular support in the region, and a source of fighters and helpers from among the general population and Bogomil followers. In addition, summer was the season when tens of thousands of people from across Bulgaria traditionally gathered in the Rila Mountains, and they likely served as a source of manpower for the army.
At that time, the Bulgarian army relied on ambush tactics and mountain warfare. The main forces were infantry, skilled as archers, giving them a clear advantage in mountain passes. Emperor Basil II advanced toward Sofia and entrusted a general named Leon Melissenos with the responsibility of supplying the army and securing the rear. However, he failed in his task, and instead of guarding the passes, he retreated to Plovdiv, thereby exposing Basil’s flank and contributing to the decision to end the siege and begin a dangerous retreat.
It is possible that Leon’s retreat and failure to deliver supplies were due to local resistance by Armenian Paulicians around Plovdiv, or attacks by Bulgarian forces operating from their Rila bases. In any case, it is clear that the local population was highly sympathetic to Tsar Samuel. This may be explained by the deep religious divide between them and the Byzantines, and their identification with Samuel, who accepted their faith.
The year of the battle—986—should also be taken into account. It was a time of religious awakening leading up to the new millennium—a thousand years after the birth of Jesus. Tsar Samuel ruled from 976 to 1014 and led a religious and cultural renaissance. The victory at the gates of Trajan allowed him to preserve an island of justice, enlightenment, and tolerance in a chaotic world, through which the new spirit of Christ for the second millennium could reach the world. The greatness and beauty of his era can be seen in the oldest church in Sofia—St. George’s Church—where paintings from his time survive, including a mysterious angel on the ceiling. Other paintings from Samuel’s time are in the Cathedral of St. Sophia in Ohrid, distinguished by their strong emotional expression.
Today, at the site of the battle at the Trajan Gates, there are remains of a fortress from the time of the Second Bulgarian Empire, and next to it a small museum room commemorating the events of the period and the 986 battle. Near the citadel are signs describing the history of Tsar Samuel and the different stages of the struggle between the Komitopuli brothers and the Byzantines, on the path to Bulgaria’s re-liberation. The modern road between Sofia and Plovdiv currently passes through the Trajan Tunnel, leaving the original foot crossings abandoned.
