Are there any civilizations in Europe trying unification as the Chinese civilization did?

The idea of a unified ancient Europe comparable to the unification achieved by Qin Shi Huang in China is complex due to the region’s diverse geography, cultures, and political structures. Unlike China’s relatively homogeneous geography, Europe is marked by a diverse landscape of mountains, rivers, and various climate zones. Additionally, Europe was home to a multitude of distinct cultures, languages, and political entities, making the prospect of a single, centralized empire challenging. (More discussion needed)

However, there were instances in European history where attempts were made to create larger political entities:

Roman Empire:

The Roman Empire, spanning from the 1st century BCE to the 5th century CE, came closest to achieving a form of European unification during antiquity. It incorporated diverse regions and cultures under a centralized governance system.

Charlemagne’s Empire:

In the early medieval period, Charlemagne, also known as Charles the Great, established an empire in the 8th and 9th centuries that encompassed a substantial part of Western Europe. Though it didn’t endure long after his death, it was a notable attempt at unification.

Holy Roman Empire:

The Holy Roman Empire, which existed from the Middle Ages to the early 19th century, sought to bring together different regions under the authority of the Holy Roman Emperor. However, its decentralized nature and the autonomy of various states within it limited true unification.

Despite these attempts, achieving the level of centralization and standardization seen in Qin Shi Huang’s China proved elusive in ancient Europe due to factors like cultural diversity, linguistic differences, and regional autonomy. Europe’s history was marked by a mosaic of kingdoms, city-states, and feudal structures, creating a patchwork of political entities rather than a unified empire comparable to ancient China.
