Alexios I Komnenos vs Timur

Alexios I Komnenos was defeated by the Norman army under Robert Guiscard at Dyrrhachium. The Byzantine forces were routed, and Alexios barely escaped. This loss allowed the Normans to occupy much of the western Balkans, though Alexios later recovered some territory.

Alexios I implemented a series of reforms to restore Byzantine power. He reorganized the army by relying more on foreign mercenaries, reformed the currency (the hyperpyron), and granted tax exemptions to the Church. These measures stabilized the empire after decades of decline.

Alexios I sent envoys to Pope Urban II at the Council of Piacenza, requesting military aid against the Seljuk Turks. This appeal contributed to Urban's call for the First Crusade at the Council of Clermont later that year, initiating the Crusader movement.

Alexios I cooperated with the Crusader army to besiege and capture Nicaea from the Seljuk Turks. The city was surrendered to Byzantine control, and Alexios used the Crusaders to recover key territories in Anatolia, though tensions later arose over land claims.

Timur defeated the Mongol ruler of the Chagatai Khanate, establishing his control over Transoxiana. This victory marked the beginning of his rise to power, as he captured Samarkand and declared himself emir.

Timur launched a campaign into Persia, capturing Isfahan and Shiraz. He suppressed a revolt in Isfahan by massacring tens of thousands of inhabitants, establishing his reputation for extreme brutality and consolidating control over the region.

Timur defeated the Golden Horde under Tokhtamysh at the Battle of the Terek River. He sacked Sarai, the Horde's capital, and destroyed its trade networks, permanently weakening the Mongol state and securing his northern frontier.

Timur invaded the Delhi Sultanate, defeating Sultan Nasir-ud-Din Mahmud Shah Tughluq. His army sacked Delhi, massacring tens of thousands of civilians and destroying the city's infrastructure, then withdrew with immense plunder.

Timur defeated the Ottoman Sultan Bayezid I at Ankara, capturing him. The victory shattered Ottoman power, leading to a civil war among Bayezid's sons and delaying Ottoman expansion into Europe for a decade.

Timur invested heavily in transforming Samarkand into a cultural and architectural center. He brought artisans from conquered lands to build mosques, madrasas, and the Bibi-Khanym Mosque, making the city a showcase of Timurid art and learning.

Timur died of illness while leading a massive army toward the Ming dynasty's borders. His death ended the planned invasion of China and led to the fragmentation of his empire among his sons and grandsons.
