How did Ottoman Turkey decline from the perspective of historical emperors?

1, the disintegration of the military fief system.

This land was originally acquired by people with military achievements. Later, it evolved into unconditional hereditary lifelong land acquisition. The direct consequence is that the troops are exhausted and the combat effectiveness drops sharply.

2. Predatory income.

Economic income is still feudal oppression of farmers, plundering industrial and commercial achievements, making industry and commerce difficult to start, and farmers are bound to the land.

The ruling class is corrupt.

The power struggle in the imperial court was fierce, and the frugal style of ancestors was abandoned and became extravagant, wasteful and corrupt.

4. Resist foreign cultures.

The Ottoman Empire believed in Islam, and its sense of self-superiority resisted all cultures from Christianity. Therefore, modern science was never introduced into the Ottoman Empire.

5. external forces incite.

Russia and Austria instilled a sense of independence in all ethnic groups in the Balkans and incited their internal independence.
