The correct answer is where the royal power was weak or non-existent
Whenever there was a king that couldn't keep everyone in line, the local lords would band up on him or would become more and more independent and it would be difficult to control them since they would often work even with foreign powers against their own lords. This led to the downfall of numerous dynasties or emperors in Europe.
Suleiman ruled from 1520-1560. In his time was regarded as the most significant ruler in the world, by both Muslims and Europeans. His military empire expanded greatly both to the east and west, and he threatened to overrun the heart of Europe itself. In Constantinople, he embarked on the vast cultural and architectural projects. Istanbul in the middle of the sixteenth century was architecturally the most energetic and innovative city in the world. While he was a brilliant military strategist and canny politician, he was also a cultivator of the arts. Suleiman's poetry is among the best poetry in Islam, and he sponsored an army of artists, religious thinkers, and philosophers that outshone the most educated courts of Europe.
Suleiman is remembered for his complete reconstruction of the Ottoman legal system. Suleiman became a prominent monarchof 16th century Europe, presiding over the apex of the Ottoman Empire's military, political and economic power. Suleiman personally led Ottoman armies to conquer the Christian strongholds of Belgrade, Rhodes, and most of Hungary before his conquests were checked at the Siege of Vienna in 1529. He annexed most of the Middle East in his conflict with the Safavids and large swathes of North Africa as far west as Algeria. Under his rule, the Ottoman fleet dominated the seas from the Mediterranean to the Red Sea and the Persian Gulf.
