At the end of the fourteenth century, the Mongol empire was known as the Timurid Empire. This empire was named after its founder, Timur, who was a Turkic-Mongol conqueror. Timur, also known as Tamerlane, rose to power in the late 14th century and established a vast empire that stretched from Central Asia to the Middle East.

The Rise of Timur
Timur was born in 1336 in what is now Uzbekistan. He belonged to a prominent Turkic-Mongol noble family and grew up during a time of political instability in the region. Timur started his military career as a mercenary, but he soon began to build his own power base and expanded his influence through a series of successful campaigns.

Timur's Conquests
Timur's military campaigns were characterized by their brutality and ruthlessness. He was known for his strategic brilliance and his ability to rally his troops. Timur conquered much of Central Asia, including modern-day Uzbekistan, Tajikistan, Turkmenistan, and parts of Kazakhstan. He also invaded Persia, Iraq, Syria, and Anatolia, defeating the Ottoman Empire and capturing the city of Damascus.

The Timurid Empire
By the end of the fourteenth century, Timur had established a vast empire that spanned from the steppes of Central Asia to the Mediterranean Sea. The Timurid Empire was a cosmopolitan and culturally rich state. Timur was a patron of the arts and sciences, and his court attracted scholars, poets, and artists from all over the Islamic world.

Timur's Death and Succession
Timur died in 1405 during an expedition to China. After his death, his empire was divided among his sons and grandsons, leading to a period of fragmentation and instability. However, the Timurid dynasty continued to rule parts of Central Asia and Persia for several generations, and their descendants played a significant role in the region's history.

In conclusion, the Mongol empire at the end of the fourteenth century was known as the Timurid Empire, named after its founder Timur. This empire was characterized by its vast territorial holdings and cultural richness, but it eventually fragmented after Timur's death.
