World map in the early 15th century – after the collapse of the Mongol Empire-under which empire did your ancestors live?

My ancestors were Portuguese, and at that time they were ruled by the Aviz dynasty.

At its peak, the Mongol Empire ruled over vast territories around the world, but its reign was short-lived.

In 1368, the Ming China rose to power and destroyed the Yuan Dynasty (the largest Mongol Khanate). In 1388, the Chinese invaded the steppes, severely damaging the Northern Yuan, which from then on existed only in name.

In 1391, the Eastern Chagatai Khanate formally submitted to the Chinese and maintained stable tribute payments.

In 1370, Timur rose to power, usurping power from the Western Chagatai Khanate and abolishing the Khanate, thus making the Western Chagatai Khanate also a state in name only.

From 1380 to 1388, Timur conquered the Ilkhanate.

In 1391 and 1395, Timur twice severely damaged the Golden Horde, turning it into a puppet state.

By the late 14th and early 15th centuries, the once invincible Mongol Empire had completely collapsed, and even the nominally existing khanates were merely puppets.

And glory certainly belongs to Ming dynasty and the Timurid Empire!

The two greatest empires of that time.
