Final answer:
The political succession pattern in Wallachia around 1420-76 was chaotic mainly due to a lack of a clear hereditary system, frequent invasions by neighboring states, and parallels with broader European political fragmentation and instability during that time.
Step-by-step explanation:
The political succession pattern in Wallachia around 1420-76 was chaotic due to a lack of a clear hereditary system. During that time, Wallachia, much like the surrounding regions, saw complex patterns of succession where power was often contested and authority was not firmly established based on lineage alone. This historical period witnessed frequent invasions by neighboring states, which further complicated the political landscape, making the succession even more turbulent.
Reflecting on the broader European context helps to understand Wallachia's struggles during that era. The feudal system prevailing in Europe often involved violent power struggles where military strength was paramount, and the rise of different groups or lords could quickly change the political order. Similarly, the Mamluk Sultanate faced unstable successions because the army chose the new sultan rather than following a hereditary system, creating a parallel with Wallachia's succession issues. In the Holy Roman Empire, political fragmentation was commonplace, despite being under the nominal control of an elected emperor.
Therefore, Wallachia's chaotic succession patterns were part of the broader European experience of political fragmentation, warfare, and the lack of clear systems for orderly succession.
